Abstract

A new reinforcing strategy for thermoplastics via hydrogen bonding bridged inorganics in the matrix was proposed. The hydrogen bonds could be formed in thermoplastics matrices with the incorporation of a little organics containing hydrogen bonding functionalities. Isotactic polypropylene (PP), polyamide 6 (PA 6), and high density polyethylene (HDPE), together with specific inorganics and organics were utilized to verify the effectiveness of the strategy. The investigations suggest that the hydrogen bonding bridged inorganics led to substantially increased flexural properties. The results of attenuated total refraction Fourier transform infrared spectroscopy (ATR-FTIR) and X-ray photoelectron spectra (XPS) indicate the formation of hydrogen bonding among the inorganics and organics in the composites.
