摘要
Abstract
NH2-CeO2/MAPP/PP/POE composites were synthesized through amino-functionalized CeO2 modification,in-corporating maleic anhydride-grafted polypropylene(MAPP)as a compatibilizer to improve dispersion within the poly-propylene(PP)matrix,and blending with polyolefin elastomer(POE).The dielectric,thermal,and mechanical proper-ties of the composites were systematically investigated.The results demonstrated that increasing the POE content elevat-ed both the dielectric constant and dielectric loss of the composites.At a test frequency of 1 kHz and a POE mass fraction of 11%,the NH2-CeO2/MAPP/PP/POE composite achieved optimal performance with a maximum dielectric constant of 4.23,accompanied by a dielectric loss of 0.0183 and elongation at break of 66.7%.关键词
