【 摘 要 】

In this paper, we present an IR and XRD study of the polypropylene fibrous nanoparticles carrier when its surface modified with rare and rare-earth elements nanoparticles using microwave irradiation, by the example of SnO2/TiO2hetero-nanoparticles. The paper shows that the smectic mesomorph structure of the non-modified polypropylene fibrous carrier transforms into the monoclinic α-crystalline due to microwave irradiation. At the same time, the carrier material remains stereoregular and keeps its helical structure.
