Abstract
- The paper investigates the process of phase separation and morphology of organic-inorganic interpenetrating polymer networks (OI IPNs) based on the cross-linked polyurethane (PU), poly(hydroxyethyl methacrylate) (PHEMA) and poly(titanium oxide) (–TiO<subscript>2</subscript>–)<subscript>n</subscript> obtained by solgel method in the presence of poly(oxypropylene glycol) (POPG) at various molar ratio of titanium (IV) isopropoxide (Ti(OPr<superscript>i</superscript>)<subscript>4</subscript>) and water. It has been established that the phase separation in OI IPNs depends on the kinetics of PHEMA-component formation and it occurs through the mechanism of the spinodal decomposition. It has been shown that by varying the ratio of IPNs components, content of inorganic component and Ti(OPr<superscript>i</superscript>)<subscript>4</subscript>/H<subscript>2</subscript>O molar ratio it is possible to control the phase separation process and obtain OI IPNs with a different phase structure.
