将经不同含量马来酸酐（MAH）改性的纳米碳酸钙以5％的比例填充聚丙烯（PP），制得PP／nano-CaCO3复合材料，并对复合材料的表面性能和机械性能进行了测试．接触角和表面性能的测试结果表明，加入适当的MAH可有效提高复合材料与水的接触角，降低复合材料的表面能和极性、色散数值．机械性能的测试结果表明，复合材料的机械性能随碳酸钙中MAH加入量的增加而提高．SEM的测试结果表明，各样品中纳米碳酸钙在树脂中的分散情况良好．
將經不同含量馬來痠酐（MAH）改性的納米碳痠鈣以5％的比例填充聚丙烯（PP），製得PP／nano-CaCO3複閤材料，併對複閤材料的錶麵性能和機械性能進行瞭測試．接觸角和錶麵性能的測試結果錶明，加入適噹的MAH可有效提高複閤材料與水的接觸角，降低複閤材料的錶麵能和極性、色散數值．機械性能的測試結果錶明，複閤材料的機械性能隨碳痠鈣中MAH加入量的增加而提高．SEM的測試結果錶明，各樣品中納米碳痠鈣在樹脂中的分散情況良好．

PP was filled with 5wt% Nanometer calcium carbonate( CaCO3 )that was modified on various content maleic anhydride(MAH). Mechanical properties and surface characteristics of pure PP and a series of CaCO3-modified-MAH/ PP composites were researched. The results of optical video contact angle and surface energy testing showed that the com- posites had lower surface energy, polar and dispersion value when it was modified on MAH. The results of impact and stretch experiments showed that the mechanical properties of composites increased with content of MAH in composites increased. The photos of SEM showed that the nano-CaCO3 in various samples was dispersed well in resin.
