本研究將導電性填充料(鎳粉，Ni)摻混至熱塑性塑膠(聚丙烯,PP)，以製備具抗靜電特性的熱塑性塑膠。摻混的方法採熔融混煉法。然後用表面電阻儀來探測樣品的導電度是否有達到抗靜電的標準。用平行板式流變儀來量測儲存模數和損失模數。用拉伸測試機來量測其斷裂拉伸率和極限強度。由研究結果中發現，PP加入鎳粉255/525之後，材料的導電度提高，在鎳粉255/525摻混10wt％時表面電阻值為10/sup 11/～10/sup 12/ Ω/sq (Surface resistivity)，已經達到抗靜電的標準了(10/sup 5/～10/sup 12/ Ω/sq)，但是鎳粉255/525加的越多斷裂拉伸率和極限強度會下降。黏彈性也隨著鎳粉255/525的增加而下降。 In this study, the electrically conductive filler (nickel powder) was blended with polypropylene by use of the Brabenda Plasti-Corder to achieve the anti-electrostatic property. The mechanical and rheological properties of the PP composite obtained were investigated with a tensile tester and the rheometer (Paar Physica, MC100) respectively. It was found that these properties deteriorate because of the poor adhesion in the interface between the polymer matrix and the filler. But, the surface electric resistivity can be decreased from above 10/sup 13/.OMEGA./sq down to 10/sup 11/.OMEGA./sq in case of the pp composite with 10wt% nickel powder.
