полиакрилонитрил

The main roads of development in industrially useful solid polymer electrolytes (SPEs) are briefly reviewed. New SPEs based on acrylonitrile copolymers PBAN and PAN and lithium salts LiAsF₆, LiCF₃SO₃, LiCIO₄ have been obtained. The limits of salts solubility in polymer matrix PBAN were established. Ion solvation and ion association processes have been studied by IR spectroscopy. Conducting properties of SPEs were measured at 20-100°C.

In the current paper electrospun nanofiber mats were derived from polyacrylonitrile (PAN). The temperature influence on the volumetric and surface composition of the resulting pyropolymers was studied by means of elemental analysis and X-ray photoelectron spectroscopy.
