We have investigated the temperature dependence of electrical conductivity and thermoelectric power (TEP) at 1.7K<T<300K in an organo metallic complex, the iodine doped poly(vinyl alcohol)–Cu 2+ chelate. We observed intrinsic metallic temperature dependence of resistivity from room temperature to 68K with a broad minimum [ρ(68K)/ρ(300K) ∼0.75], which has not been observed previously...
We have evaluated the mechanical strength of a series of composites consisting of carbon particles bound together by poly(vinylidene fluoride) (PVDF), which is closely related to the carbonaceous anode in a lithium ion battery. We used a balanced beam scrape adhesion tester and evaluated the influence of carbon particle structure, the chemical properties of PVDF, and the processing parameters of annealing...
