Описание: Ionic polymer metal composites (IPMCs) can generate a voltage when physically deformed. Conversely, an applied small voltage or electrical field can induce an array of spectacular large deformation or actuation behaviours in IPMCs, such as bending, twisting, rolling, twirling, steering and undulating. An important smart material, IPMCs have applications in energy harvesting and as self-powered strain or deformation sensors, especially suitable for monitoring the shape of dynamic structures. Other uses include soft actuation applications and as a material for biomimetic robotic soft artificial muscles in industrial and medical contexts. This comprehensive set on ionic polymer metal composites provides a broad coverage of the state of the art and recent advances in the field written by some of the world’s leading experts on various characterizations and modeling of IPMCs. The first two chapters cover the fundamentals of IPMCs and methodologies for their manufacture, followed by specific chapters looking at different aspects of actuation and sensing of IPMCs. These include uses in electrochemically active electrodes, electric energy storage devices, soft biomimetic robotics artificial muscles, multiphysics modeling of IPMCs, biomedical applications, IPMCs as dexterous manipulators and tactile sensors for minimally invasive robotic surgery, self-sensing, miniature pumps for drug delivery, IPMC snake-like robots, IPMC microgrippers for microorganisms manipulations, Graphene-based IPMCs and cellulose-based IPMCs or electroactive paper actuators (EAPap). Edited by the leading authority on IMPCs, the broad coverage of this book will appeal to researchers from chemistry, materials, engineering, physics and medical communities interested in both the material and its applications.

Описание: This books opens with an evaluation of the effects of the acid environment on sulfur-polymer matrix composite, with Portland cement-based composite chosen as a comparative material. Unlike conventional Portland cement-based composites, sulfur-polymer matrix composites are produced without water and achieve final strength in few days. Following this, the effects of electron beam irradiation on copper oxide added polymer matrix composite was investigated. Copper oxide added polymer matrix composite has been known for engineering applications that involving plastics moving parts to reduce friction. In a separate study, inorganic Montmorillonite nanofibers and organic cellulose nanofibers obtained through acid hydrolysis were simultaneously added to plasticized starch with defined CNF-to-MMT ratio and processed into nanocomposites by melt extrusion. The continuously isothermal aerobic ageing on samples was carried out by oven-heating at 60°C so as to investigate the organic nanofillers as an alternative to inorganic nanofillers. The authors also investigate the physico-mechanical characteristic of low density polyethylene (LDPE) and starch blends when undergone acid and alkaline attacks. In the following chapter, simulation of the temperature distribution in textile composite structures is achieved by utilizing an analytical-symbolic approach. Analytical heating solutions along each yarn provide accurate solutions with far fewer nodes than numerical solutions, and require the minimum number of symbolic network nodes. The final investigation was conducted to investigate the effects of copper (II) oxide (CuO) composition on the degradability of high density polyethylene/ethylene vinyl acetate (HDPE/EVA) blends. It was observed that both degree of crystallinity and crystallites sizes of the composited increased after the ageing operation.

Описание: In nature, green polymers (natural polymers) in plants and animals always coexist with water. The characteristic features of polymers organized in nature are difficult to understand without water. Specific features of green polymers are characterised via interaction with water molecules which strongly interact with the hydrophilic group of polymers. Molecular motion of the main chain of polysaccharides, whether extracted from wood, fungi, seaweed, or bacteria, is considerably enhanced in the presence of water. Not only in crystalline polysaccharides but also amorphous lignin, the effect of water on molecular motion is clearly observed by various experimental techniques. When the molecular motion of green polymers is investigated in the presence of water, molecular rearrangement occurs by the introduction of water into the system, and the higher-order structure is rearranged during molecular movement by heating conditions. Phase transition behaviour of water molecules is also affected in the presence of hydrophilic polymers, such as polysaccharides. Molecular enhancement of water molecules and hydrophilic polymers cooperate with each other and phase transition behaviour of the above system also corresponds to the above motion. Even the first-order phase transition of water is affected in the presence of polysaccharides. When glass transition behaviour of the natural polymer-water system is investigated, it is important to take into consideration the fact that the structural change of both components has necessarily taken place. In this book, the molecular relaxation of green polymers, especially the thermodynamic concept of green polymers and the bound water, will be described in Chapter 2. Various techniques to measure the glass transition of green polymers in dry and wet conditions are explained in Chapter 3. Special attention is paid to sample handling for controlling water content. Glass transition behaviour of various polysaccharides and model compounds is described in Chapter 4. An explanation of lignin and its synthetic model polymers is also given in Chapter 5.
