Abstract
A series of three silsesquioxanes (containing either the original organic function (SH) (silsesquioxane 2, SH_SS), a derivatized one (NH3Cl) (silsesquioxane 1, A_SS) or completely chloro derivative (silsesquioxane 3, Cl_SS)) were obtained by acid hydrolysis of the three organo-trialkoxysilane (3-aminopropyltriethoxysilane, 3-mercaptopropyltrimethoxysilane and 3-cyanopropyltriethoxysilane). The biological compatibility was tested for the three composite films. The values of water vapors sorption capacities increase in the following order: P_Cl_SS < P_SH_SS<P_A_SS. Depending on the silsesquioxane type, an increasing of the dielectric constant value up to 4.5 as compared with the value for the silicone matrix was obtained. The bactericidal performance in environmental applications of the newly blends with specific microarchitecture, controlled porosity and higher hydrophobicity, is measured by its ability to maintain the balance between the biological selectivity and membranes functionalization as disinfection materials.
