A novel method to prepare high-resistivity polymer composites

A novel method was developed for the preparation of high-resistivity conductive polymer composites reproducibly. The conventional method which involves the simple mixing of a conductive filler and a polymer usually produces a conductive polymer composite having a loading curve with a region in which the resistivity changes rapidly as the filler concentration changes. Hence, it is very difficult to obtain reproducible materials in that region. This newly developed method involves the preparation of a conventional conductive polymer composite, which is prepared by the simple mixing of carbon black and a polymer as the first step. The resulting compound, which is crosslinked by either electron-beam radiation or a chemical-crosslinking agent, is ground into a fine powder (composite filler) with the particle size less than 250 microns. The composite filler is mixed with another polymer to form a conductive particulate composite which has a loading curve showing a more gradual change of resistivity as a function of filler concentration. The modification of the loading curve is controlled by the resistivity, the shape, and the size of the composite filler.

Anion conductive polymer nanofiber composite membrane: effects of nanofibers on polymer electrolyte characteristics

Polymer composite membranes composed of anion conductive polymer nanofiber mats and the corresponding polymer matrix were prepared and characterized for future alkaline fuel cells. In this paper, electrospinning was attempted to fabricate anion conductive nanofiber mats. The anion conductivity of the composite membrane was higher than the corresponding membrane without nanofibers under all conditions due to outstanding anion conductive characteristics of the nanofibers. In addition, because of the rigid and anisotropic structure of the nanofibers, membrane stabilities such as reductive degradation resistance and mechanical strength were very much improved. The gas permeability and excessive hydration swelling that will degrade fuel cells after long‐term operation were suppressed in the nanofiber composite membrane. These results indicated that excellent properties of the anion conductive nanofibers were demonstrated even in the composite membrane, leading to the potential application of anion conductive nanofibers in future fuel cells. © 2016 Society of Chemical Industry
