Abstract

Organophosphorus coupling molecules are much less widespread than organosilicon compounds, but they are finding increasing applications. In this paper we present the use of polyvinylphosphonic acid as precursor in synthesis of new organic-inorganic hybrids with interpenetrated network, using sol-gel method, under ultrasound conditions. The interpenetrated network is a results of two networks coupled through covalent bonds. The covalent bonds are produced by polycondensation between M-OH and P-OH groups from alkoxide and polyvinylphosphonic acid respectively. The obtained hybrids were investigated using FTIR, SEM, and AFM.
