| Abstract: | In order to obtain an optimized method for compounding, the influence of different nano SiO2particle doping methods on polyurethane materials was investigated in this work. Nano SiO2 particles were prepared by sol-gel process, and polyurethane/SiO2 nano-composite materials were prepared by different nano-SiO2 particle doping methods. The chemical structure of nano-composites were characterized by infrared spectroscopy (IR) ,and the mechanical properties, thermal stability and color contrast properties of the polyurethane/SiO2 nano-composite materials were studied by universal electron tester, dynamic mechanical analyser (DMA),differential scanning calorimeter (DSC) and UV/VIS/VIR spectrophotometer. |

| Keywords: | nano SiO2 particle sol-gel polyurethane resin nano composite mechanical property heat-resistant color contrast properties anti adhesive properties |
