Abstract

Polyamidhydroxyurethane becomes in the presence of water, a non-biodegradable hydrogel with a high capability of water sorption, exhibiting rubbery behaviour and good biocompatibility. When prepared with less content of water and suitable mixing hydrogel components, this becomes a promising biomaterial for artificial hard/soft tissue in biomedical applications. In this paper, the less-water films of polyamidhydroxyurethane are discussed, and are analysed the nature of inter- and intra- molecular interactions. Using X-ray diffraction, optical microscopy with polarized light, steady-state linear dichroism, infrared and UV-ellipsometry, the network structure of water in film of polyamidhydroxyurethane was determined. Water exhibits a high degree of homogeneity and consists of three phases: a water phase of low polyamidhydroxyurethane concentration, an amorphous phase, and a crystalline phase that restricts the motion of the amorphous domains..
