Properties of coatings of high styrene thermoplastic elastomers and their modifications

Abstract

Flexible fiber-optic cables, used to prevent stomach diseases, protected by disposable and transparent coatings reduce the duration of disassembly and sterilization. The aim of this work was to develop technologies for producing films, protective coatings of high-styrene block copolymers StyroTEP-65 and estimation of their technical parameters. It was determined the impact of the multiplicity of dippings in polymer solution and polymer solution concentration, layer thickness and nature of the sub-strate on the elastic strength properties of the films. The manifestation of the anisotropy of the properties in the longitudinal and transverse cross sectio n of the membranes is fixed. The increase in the thickness of the membranes resulted in a slight decrease in light transmission in the visible and infrared wavelength range. Results of physico-mechan ical properties of the films StyroTEP-65 in the presence of polyvinylcarbazole additives are presented. Method for casting membranes is developed, their optimal thickness is determined, the effect of the anisotropy properties of the membranes in the longitudinal and transverse cross-section is observed.
