Book Description
To develop devices for improving the quality of life such as handheld electronics, artificial muscles, lab-on-chip devices, etc., the quest for future smart materials has led to increasing interest in Conducting Polymers (CPs). Recent technological advancements have already exploited the many advantages of CPs, but to further their usability, we require a reliable and robust means of fabricating CPs at micrometric scales. This research work focusses on demonstrating these fabricated CP micro-structures’ applicability in biomedical applications and, more specifically, as a means of sensing and measuring air flow levels observed during neonatal resuscitation. In this thesis, I present a reliable means of fabricating three-dimensional CP microstructures, in particular focusing on fabricating hair-like microstructures from Poly(3,4-ethylenedioxythiophene) Poly(styrene sulfonate), referred to as PEDOT:PSS. A 3D printer was developed with capabilities of producing microscopic patterns and structures using miniaturized pipettes for dispensing the CP material. A Graphical user interface was also developed to allow human interface with the microstructure printer. A novel flow sensor prototype was developed using PEDOT:PSS micro-hairs, where these micro-hairs act as microscopic switches which open and close in response to air flow. By using an array of micro-hairs that respond to specific flow velocities, a discrete digital output flow sensor was demonstrated. A means of improving the sensitivity of the flow sensor to lower flow velocities was also demonstrated by printing the micro-hairs within a narrow convergent-divergent flow channel. To improve the understanding of the flow sensor’s response to air flow by simulating the Fluid-structure interactions (FSI), a robust mathematical model was developed. Based on Lattice Boltzmann equations for simulating the fluid flow in a 3D domain and beam theory for simulating large deflections, the model was exclusively coded in MATLAB. Using dimensional transformations to minimize the computational costs, a mixed 2D and 3D simulation for the developed FSI model is presented. Using the FSI model, a final sensor prototype was developed specifically to be compatible with the target neonatal resuscitator device. Apart from being capable of measuring the ultra-low velocity flows experienced during neo-natal resuscitation to meet the demands of the target application, this prototype sensor was designed to be portable with the capability of reading out flow levels directly integrated with the sensor. Furthermore, the portable sensor was also developed with a disposable architecture to improve medical compatibility. By successfully demonstrating the capabilities of fabricating CPs in micrometric scales and using these microstructures as a suitable means of sensing air flow through the development of an ultra-low velocity flow sensor, the suitability of using CP microstructures in real world applications has been demonstrated.

Book Description
This book provides a comprehensive overview on the recent significant advancements of conductive polymers and their composites in terms of conductive mechanism, fabrication strategies, important properties, and various promising applications. The corresponding knowledge was systematically compiled in the logical order and demonstrated as seven chapters. The special structure, influencing factors of the conductivity, the charge carrier transport model, the wettability and classical categories of the conductive polymers are narrated. Both conventional and novel strategies undertaken to fabricate the conductive polymers are introduced, as provided the overall master of the progress. In comparison with the bulk counterpart, nanostructured conductive polymers with different dimensions such as nanospheres, nano-networks, nanotubes and nanowire arrays are produced through distinct methods, thus presenting unique and distinct performance endowed by the nanometer scale. The combination of conductive polymers with other functional materials results in a number of the composites with improved properties by synergistic effect. The superior performance of conductive polymers and their composites greatly facilitates their development toward various important applications in the advanced and sophisticated fields such as biological utilization, energy storage and sensors. Due to their excellent biocompatibility, conductive polymers and their composites stand out to be useful in the biological field including tissue engineering, drug delivery and artificial muscle. To meet the urgent demand of the energy storage, conductive polymers and their composites play an important role in the devices including supercapacitors, solar cells and fuel cells. Finally, development of conductive polymers and their composites in the modern industry is greatly enhanced by their applications in smart sensors such as conductometric sensors, gravimetric sensors, optical sensors, chemical sensors and biosensors. This book has significant value for researchers, graduate students, and engineers carrying out the fundamental research or industrial production of conductive polymers and their composites.

Book Description
Chemically-modified carbon nanotubes (CNTs) exhibit a wide range of physical and chemical properties which makes them an attractive starting material for the preparation of super-strong and highly-conductive fibres and films. Much information is available across the primary literature, making it difficult to obtain an overall picture of the state-of-the-art. This volume brings together some of the leading researchers in the field from across the globe to present the potential these materials have, not only in developing and characterising novel materials but also the devices which can be fabricated from them. Topics featured in the book include Raman characterisation, industrial polymer materials, actuators and sensors and polymer reinforcement, with chapters prepared by highly-cited authors from across the globe. A valuable handbook for any academic or industrial laboratory, this book will appeal to newcomers to the field and established researchers alike.

Book Description
Polymers with redox properties are electroactive macromolecules containing localized sites or groups that can be oxidized and reduced. Depending on the oxidation state, redox polymers can present different electronic, optical, mechanical or chemical properties. These polymers are finding new applications in materials science, as well as being included in the design of a number of electrochemical devices. Redox Polymers for Energy and Nanomedicine highlights trends in the chemistry, characterization and application of polymers with redox properties. The book starts with an introduction to redox polymers and covers several important topics including redox polymer types, state-of-the-art characterization techniques, synthetic strategies and theory and computational studies. The second part is devoted to the redox polymers applied in energy and nanomedicine. First, the most important redox polymer families in energy storage are reviewed, i.e, radical, phenothiazine, carbonyl and catechol containing polymers. The book also contains recent developments in redox polymers for biofuel cells and all-organic batteries. Second, the emerging applications of redox polymers in nanomedicine technologies such as, tissue engineering, drug-delivery, actuators or biosensors are explained in detail. With contributions from global experts, the book will be of interest to graduate students and researchers working in polymer science, electrochemistry, energy research and nanomedicine.
