Conducting polymers are rapidly gaining attraction in new applications with increasingly processable materials with better electrical and physical properties and lower costs. The new nano-structured forms of conducting polymers particularly, augment this field with their higher surface area and better dispersability.
Electroactive polymer. (a) Drawing of an EAP gripping device. (b) A voltage is applied and the EAP fingers deform in order to release the ball. (c) When the voltage is removed, the EAP fingers return to their original shape and grip the ball. An electroactive polymer (EAP) is a polymer that exhibits a change in size or shape when stimulated by ...
Polymers such as PMMA and HEMA:MMA are used as matrices in the gain medium of solid-state dye lasers, also known as solid-state dye-doped polymer lasers. These polymers have a high surface quality and are also highly transparent so that the laser properties are dominated by the laser dye used to dope the polymer matrix
Polymer electrolytes. A polymer electrolyte is a polymer matrix capable of ion conduction. [1] Much like other types of electrolyte —liquid and solid-state —polymer electrolytes aid in movement of charge between the anode and cathode of a cell. [1][2][3] The use of polymers as an electrolyte was first demonstrated using dye-sensitized solar ...
Polyaniline (PANI) is a conducting polymer and organic semiconductor of the semi-flexible rod polymer family. The compound has been of interest since the 1980s because of its electrical conductivity and mechanical properties. Polyaniline is one of the most studied conducting polymers. [2][3]
Polypyrrole. Polypyrrole. Pyrrole can be polymerised electrochemically. [1] Polypyrrole (PPy) is an organic polymer obtained by oxidative polymerization of pyrrole. It is a solid with the formula H (C 4 H 2 NH) n H. It is an intrinsically conducting polymer, used in electronics, optical, biological and medical fields. [2][3]
Polymer engineering is generally an engineering field that designs, analyses, and modifies polymer materials. Polymer engineering covers aspects of the petrochemical industry, polymerization, structure and characterization of polymers, properties of polymers, compounding and processing of polymers and description of major polymers, structure property relations and applications.
A thermoplastic, or thermosoftening plastic, is any plastic polymer material that becomes pliable or moldable at a certain elevated temperature and solidifies upon cooling. [1][2] Most thermoplastics have a high molecular weight. The polymer chains associate by intermolecular forces, which weaken rapidly with increased temperature, yielding a ...
