纳米CeO2/水性聚氨酯复合材料的制备及性能
Preparation and properties of nano CeO2/waterborne polyurethane composites
摘要
Abstract
The nano CeO2 sol was synthesized by sol-gel method,and then a series of nano CeO2/waterborne polyurethane composites(CMWPU)were prepared by blending the nano CeO2 sol with waterborne polyurethane(MWPU). The structure and properties of CMWPU composites were characterized by DLS,UV-Vis,SEM,XRD,TGA and so on. The effects of the content of nano CeO2 sol on the properties of CMWPU composite emulsion and its film were also discussed. The results showed that CMWPU composites were successfully prepared by adding nano CeO2 sol,and the nano CeO2 sol was dispersed evenly in the CMWPU composite. When the content of nano CeO2 sol was 7.0%,the UV absorption effect of composite emulsions was the best and the absorbance value reached 0.63. Compared with MWPU,the thermal stability of CMWPU film has been improved. The temperature corresponding to maximum thermal decomposition rate increased by about 63.4℃,and the tensile strength of the composite film was up to 52.63MPa.关键词
