Abstract:In this study, a TiO2/polyurethane composite (PU-TiO2) for photodegradation of formaldehyde was prepared based on TiO2 amino-functionalized with 3-aminopropyltriethoxysilane (APTS). FTIR, XPS, TG and TEM measurements demonstrated the successful amino-functionalization of TiO2 by APTS. Then the NH2-TiO2 were incorporated into polyurethane (PU) through urea linkages, and the thermal stability, mechanical properties as well as degradation efficiency of PU-TiO2 were investigated. PU-TiO2 possessed good thermal sta… Show more
