The nanocomposites based on polyurethane (PU), poly(2-hydroxyethyl methacrylate) (PHEMA), and nanofiller densil are created. Dynamic mechanical properties, morphology by SEM and hydrophilicity of the materials are investigated. The dependence of the characteristics on the polymer matrix components content and amount of nanofiller is evaluated. It has been shown that the introduction of nanofiller into multicomponent polymer matrix with a small amount of second component, which is characterized by a low degree of polymer components segregation, leads to an increase in the modulus of elasticity of the materials. In such nanocomposites, there is a more free segmental motion in PHEMA, indicating the concentration of the nanofiller mainly in the PU’s nanodomains. When the nanofiller is introduced into the matrix with a significant degree of microphase separation, an increase in the elastic modulus is observed only at high amounts of nanofiller (10–15%), which plays the role of a compatibilizer. In the morphology investigation it has been shown that the matrix has a phase-separated structure. When 3–5 % of densyl is added to the matrix, a smoother, integrated structure appears. With the further increase of nanofiller amount up to 10–15 %, formation of nanofiller aggregates is observed, while aggregates become more densely packed with fraction of the nanofiller. The hydrophilicity of the created materials increases due tu introduction of both PHEMA and nanofiller densil, but nonmonotonic changes with amount of nanofiller occurs. Concentration dependence of water sorption is determined by the distribution of filler nanoparticles in the matrices, its aggregation at 10–15 % content, and by the formation of surface layers of polymer components of matrices, which can consist of polyurethane or of both polymer components of multicomponent polymer matrices. The introduction of nanofiller densyl leads to the increasing of the hydrophilisity of created materials and so to the increasing of their biocompatibility. Created nanocomposites could be effective as materials for bio-medical applications.
