导电聚合物(塑料)业已接近技术突破的边缘。现已制成两种导电聚合物聚乙炔(PAC)和聚吡咯(PPY)的复合物。这种复合物克服了单种聚合物固有的缺点。 PAC具有塑料的全部机械性能的优点,加之有高的多孔性、大的表面积(作为电极材料这是极好的)。但它在空气和水中经常不稳定,并易于失去其导电性。这就严重地限制了它在轻型电池中的应用。另一方面,PPY则十分稳定,并能保持其导电性,但它的机械性能差而且很脆。美国IBM实验室制成的PPY和PAC的复合物克服了PPY的缺点。其方法是在铂电极上涂复PAC膜,将它作为电解液中含有吡咯的电化学电池的部件。吡咯溶液的电聚合导致在PAC涂层内生长PPY Conductive polymers (plastics) are close to the brink of technological breakthroughs. A composite of two types of conductive polymer polyacetylene (PAC) and polypyrrole (PPY) has been made. This complex overcomes the inherent disadvantages of a single polymer. PAC has all the mechanical properties of plastic advantages, combined with high porosity, large surface area (as the electrode material which is excellent). But it is often unstable in air and water and tends to lose its conductivity. This severely limits its use in light batteries. PPY, on the other hand, is very stable and retains its conductivity, but its mechanical properties are poor and brittle. The PPY and PAC composites made by the IBM lab in the United States overcome the shortcomings of PPY. The method is to coat the platinum electrode with PAC film as a component of the electrochemical cell containing pyrrole in the electrolyte. Electropolymerization of the pyrrole solution resulted in the growth of PPY within the PAC coating
