Abstract

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.

摘要： 采用溶胶-凝胶法合成了纳米CeO₂溶胶，然后将合成的纳米CeO₂溶胶与水性聚氨酯（MWPU）共混，制备了一系列纳米CeO₂/水性聚氨酯（CMWPU）复合材料。采用DLS、UV-Vis、SEM、XRD、TGA等表征了CMWPU复合材料的结构和性能，探讨了纳米CeO₂溶胶质量分数对CMWPU复合乳液及其膜性能的影响。结果表明：加入纳米CeO₂溶胶后成功制备了CMWPU复合材料，纳米CeO₂溶胶在CMWPU复合体系中分散均匀。当纳米CeO₂溶胶质量分数为7.0%时，复合乳液紫外吸收效果较好，其吸光度值达到0.63。与MWPU相比，CMWPU复合膜耐热性得到提高，最大热分解速率对应的温度提高了63.4℃，拉伸强度达到52.63MPa。
