Paper Abstract

The microstructure of the polymer composite based on the LC- cellulose derivative and poly(acrylonitrile) was investigated. The polymer composite was obtained by photopolymerization of the mechanically oriented (shearing) lyotropic LC-solution of the (2-hydroxypropyl)cellulose (HPC) in the acrylonitrile (AN). The use of multiple techniques: dielectric, thermogravimetric, mass spectroscopies, and thermooptical analysis enabled to overcome resolution problem related to behavior of the non- mesogenic polymer network of poly(acrylonitrile) in the mesogenic environment of the HPC. The results of the investigation of the composite microstructure show that the polymer composite is composed of two subsystems: mesogenic system of cellulose derivative and oriented fibril-like polymer network which is formed by non-mesogenic poly(AN). The polymer network of poly(AN) influences the optical anisotropy relaxation of the mesogenic HPC in the composite.
