Kazan: KSTU Publishing House, 2011. 364 s. — ISBN 978-5-7882-1059-9 . The structures of natural collagen and keratin-containing materials, as well as structural changes of materials in the processes of processing and HF plasma modification are considered. The results of experimental studies of modification of materials of leather and fur industry in plasma of high-frequency discharge of low pressure are given. Mathematical models of structural HF plasma modification of collagen- and keratin-containing materials are described. Designed for a wide range of researchers and specialists dealing with skin and fur technology, low-temperature plasma physics, teachers, graduate students and university students . Prepared at the Department of Plasmochemical and Nanotechnology of High-molecular Materials .
