ABSTRACT

By introducing organic modified nano silica, recycled PET comes to life again. Organic layer improves the compatibility between SiO2 and polyester, making fillers fine disperse in matrix. Nano silica acts multiple roles which greatly enhances the viscosity, crystallinity and mechanical properties of nanocomposites. The strategy proposed is beneficial to efficiently reuse recycled PET with small amount of nano fillers.
