The SEM Application for Diagnostics of Polyethylene Films Suitability for Information Recording by Thermal Printing

The diagnostics of polymer films suitability for information recording by thermal printing was carried out. The specific fibrillar structure of commercially available polyethylene films, which have high sensitivity to a fast recrystallization of some parts of surface fibrils during short-term heating at a lower temperature than the melting temperature of polyethylene crystalline grains, was found. Views and dimensions surface layers nanostructured elements as probable reasons of thermal printing contrast were estimated. The temperature effect on optical parameters of films was defined.
