Study of tribological evaluation of nanofibers/webs

点击翻译按钮获取中文摘要

A versatile tester has been developed for evaluation of mechanical strength, stress relaxation, three point tensile strength and etc. of a nano/micron size fiber. Effects of diameter, environment and etc. on the mechanical properties of various fibers are clarified as well as optimization of sample holding method and the configuration. The optimum synthesis of polyurethane, nylon-6, polypropylene etc. and their post treatment method such as metallization were established. Their tribological and tribo-electrical properties were also investigated.
