  • 本研究主要針對銅錫(CuSn)合金/高密度聚乙烯(PE)及改性銅錫(CuSn)合金/高密度聚乙烯(PE)的導電性能做了一系列探討。研究發現,相較於(CuSna/b)xPEy樣品,經異丙基三(二辛基焦磷醯氧基)鈦酸異丙酯(LICA38)改性之 (CuSna/bLc)xPEy樣品樣品的體積電阻率均明顯降低。而且,相較於混煉法,球磨法製備之 (CuSna/b)xPEy樣品的體積電阻率亦顯著降低。同時,球磨法製備之不同厚度(CuSna/b)xPEy樣品的體積電阻率隨著厚度的減小而明顯降低。為瞭解上述有趣的現象,本研究對純CuSn合金,經LICA38改性CuSn合金樣品的紅外光譜及表面形態,(CuSna/b)xPEy 和(CuSna/bLc)xPEy樣品的熱學性質和導電性能進行了探討。


    In this experiment, the conductivity properties of high density polyethylene (HDPE) composites filled with (Cu-Sn ) Alloy and modified Cu-Sn Alloy (MCu-Sn ) which was modified with LICA38 . Investigates indicated that the Volume Resistivity of (CuSna/bLc)xPEy is lower than (CuSna/b)xPEy. In addition, Volume Resistivity of (CuSna/b)xPEy prepared by ball milling method decreased with thickness increa. The Fourier Infrared(FTIR),differential scanning calorimetry (DSC)and multiple function micro-electrical resistance meter (KEITHLEY2700) were used to study the surface morphology, thermal and electrical properties of (CuSna/b)xPEy and (CuSna/bLc)xPEy.
