This review article explores typical recent applications of conductive polymers (2016–2020) as active electrode materials for energy storage applications, electrochemical sensing, and conversion fields such as electrochemical supercapacitors, lithium-ion batteries, fuel cells, and solar cells.
What are the current industrial applications of conductive polymers?
Electrically conductive polymers show great potential and are currently employed in various applications such as supercapacitors, light emitting diodes (LED), artificial muscles and biosensors [1].
What is conductive polymer composites?
Conductive polymer composites are mainly composed of conductive fillers with high conductivity and insulating polymer matrices, in which conductive fillers provide carriers. The carriers transfer into polymer composites by interaction between conductive fillers.
Which polymer is electrically conductive?
2.1 Polypyrrole (PPy) Doped PPy has been the most thoroughly investigated conductive polymer for biomedical applications because of its high electrical conductivity, ease of preparation, and ease of surface modification.
What are conducting polymers explain their classification and applications?
Conductive polymers or, more precisely, intrinsically conducting polymers (ICPs) are organic polymers that conduct electricity. Such compounds may have metallic conductivity or can be semiconductors. The biggest advantage of conductive polymers is their processability, mainly by dispersion.
What are conducting polymers with examples?
Typical conducting polymers include polyacetylene (PA), polyaniline (PANI), polypyrrole (PPy), polythiophene (PTH), poly(para-phenylene) (PPP), poly(phenylenevinylene) (PPV), and polyfuran (PF) (Chart 1).
What are the applications of polymers as plastics in electronics?
POLYMERS ARE INCREASINGLY BEING USED in a wide variety of applications in electronics and photonics, most of which use polymers in their traditional role as engineering materials (e.g., circuit boards, molded products, wire and cable insulation, encapsulants, and adhesives).
What are the commonly used polymers and what are their uses in electrical engineering?
Among the main elastomers, polymers commonly used in electrical applications are silicone, ethylene propylene rubber (EPR) and ethylene propylene diene monomer (EPDM). The elastomers such as silicone, EPR and EPDM are major elemental materials for polymer insulators [37–40].
Why do we need conducting polymers?
Applications of Conducting Polymers They are used in the manufacturing of chemical sensors, electro-magnetic shielding, antistatic coatings, corrosion inhibitors, etc. They are also used in compact electronic devices such as polymer-based transitions, light-emitted diode (LEDs), and lasers.
What are conducting polymers explain its classification and applications?
How do conducting polymers conduct electricity?
Polymers have long been known as insulating materials and are often used to insulate cables and electrical devices. However, there are also a number of polymers that are electrically conductive. The electrical conductivity of these polymers is based on the presence of conjugated double bonds along the polymer backbone.
What are the applications of composites in electronic industry?
Applications in the Electrical Industry Phenolic-matrix and melamine composites are used in many electronics including printed circuit boards, gears, and insulators. Insulation, circuit boards, and components requiring a high resistance to heat will often be made from a silicone-based composite.
How can polymers be made to conduct electricity?
By doping, the conductivity of the polymer increases from 10-3 S m-1 to 3000 S m-1. An oxidation doping (removal of electrons) can be done using iodine. The iodine attracts an electron from the polymer from one of the pi bonds. Thus the remaining electron can move along the chain.
Which of the following is not an electrically conducting polymer?
question. Polyethylene is not a conducting polymer.
Which of the following are advantages of conductive polymers?
4.4 Conducting polymers Compared to transition metal oxides or hydroxides, CPs exhibit a large number of advantages such as low costs, flexibility, large theoretical specific capacitance, environmental stability, good electrical conductivity, and ease of large-scale production [89].
Can polymers be used to conduct electricity?
To become an electrical conductor, a polymer must be conjugated. In other words, the chain of carbon atoms must be strung together around single and multiple bonds making the structure of the material fairly comparable to that of silicon.
What are the applications of nonlinear composite materials in HV engineering?
Current Applications of Nonlinear Polymer Composites in HV Engineering The composite materials with nonlinear properties have an important role in HV systems as they can reduce the electric field stress, which is the origin of electrical aging and insulation failure.
Which is the best filler material for nonlinear conduction?
Polymer Composites with a Single Particle Type 4.1. ZnO-Based Composites ZnO is one of the most used filler materials for nonlinear conduction applications. At low electric fields, it exhibits a linear current–voltage relationship.
What are the different types of conductive materials?
The second type consists of technologies based on conductive layers that are applied in the area with the highest electrical stress, and stress control is based on the positions and dimensions of the insulating and conductive layers. Typical conductive materials include graphite, conductive polymeric and carbon black tapes, and metallic foils [22].
What are nonlinear conductive materials?
Nonlinear conductive materials enable the grading of electric-field distributions in polymeric outdoor insulators, particularly near the high-voltage and ground terminals [125]. It is also possible to find nonlinear materials in cable accessories [22,36,61], such as cable joints and HVDC cable terminations (Figure 50) [37,126].
