本研究將竹炭與銀兩種不同的材料結合,研發出金屬結合非金屬的複合導電材質;利用銀鏡反應,以竹炭當作載體,製作出竹炭-銀複合物,透過自製竹炭-銀電壓與電流的裝置,發現竹炭-銀錠最佳導電的質量比例為竹炭比銀1:9,利用掃描是電子顯微鏡,分析竹炭-銀複合物,發現銀會有效分布在竹炭表面形成包覆,竹炭銀定可導電,電阻介於純銀與炭之間,其電阻極低,將來可應用在代替石墨作為電池的電極,對提升導電度會有幫助;In this work, using the silver-mirror reaction, porous bamboo charcoal has been successfully adopted as novel supports for immobilization of silver nanoparticles by a chemical reduction method and the metal-nonmetallic composites with conductivity efficacy were investigated. Through the test of homemade voltage with the electric current instrument, we found out that the best ratio of conductivity in the bamboo charcoal-silver ingot is 1:9. Scanning electron microscopy (SEM) of the composites show uniform Ag particles distribution on the BC matrix. The bamboo charcoal-silver ingot has the conductivity. The resistance, between the pure silver and the coal (graphite), is extremely low. Thus, this composite will promote conductivity and apply in the battery of electrode for replacing the graphite in the near future.
