Excitation of the soliton-type wave of change of reflection and conduction in the rubber: new experimental data important for its mechanism development

摘要

It was shown experimentally, that in elastic soft polymer samples such as rubber the IR-laser pulse excites components of the soliton-like Wave of change of reflection and conduction (WCRC). It is most probable, that the arrival of a wave results in local decreasing of the temperature of different rubber samples. At room temperature the WCRC velocity measurement for two vacuum rubber samples with different thickness given agreeable data correspond to the nineteenth WCRC component. In crude, not polymerized rubber and at cooling of vacuum rubber up to ～230 K the WCRC also was excited. As well as in researches with plexiglas, in the present work the effect of "saturation" of a new sample by components of soliton-like WCRC was observed. The obtained data confirm availability of "soliton" properties for studied WCRC and inapplicability of the dislocations recombination mechanism as the causes resulting in formation WCRC. These results are important for the WCRC mechanism development. It presents a phenomenon, which in process of its research appears to be more and more universal. The work was made at financial support by RFBR, project 00-02-17249-(a), and by KIE.
