Beta-silicon carbide whisker-polymer composites

Modified silicon carbide whisker reinforced polybenzimidazole used for high temperature proton exchange membrane

“…SiC whisker grown by single crystal can also improve various properties of the polymer matrix due to the special fiber-shaped structure. Liepins et al [28] first introduced β-SiC whisker into PBI to prepare PBI/ β-SiC composite by solution-casting method, which, however, was not used for PEM. To our knowledge, there has been no study on SiC whisker for HT-PEMs.…”

AC Electrical Properties of Epoxy/Silicon Carbide Whiskers Composites Coated with TiO 2 and Poly(divinylbenzene)

“…Coatings are described as nano-layer or nano-structured when the thicknesses of layers in the coatings or their grain size are below 200 nm. Formation of phases, and their distribution in multi-phase and multi-layer coatings, occurring during the process of coating deposition, leads to exceptional properties of such coatings higher than, exceeding the hardness of layers or phases present in the coating; this usually occurs in nano-scale coatings [3][4][5][6][7][8]. In this article we describe the AC electrical properties of epoxy/SiC w coated with titanium dioxide (named as WTiO 2 ) and epoxy/SiC w coated with poly(divinylbenzene) (named as WPOL), whiskers composites measured through the powerful impedance technique.…”
