技術說明

一種石墨-乙烯酯樹脂複合材料導電板之製備方法，該導電板可作為燃料電池的雙極板、染料敏化太陽能電池的對電極及釩液氧化還原電池的電極。本發明方法包含下列步驟：a)捏合石墨粉末與一乙烯酯樹脂，形成一均質之模塑混合物(BMC)，所述石墨粉末的量為70至95重量%，以該模塑混合物的重量為基準，並在捏合過程進一步添加官能基化石墨烯0.01至15重量%，以該乙烯酯樹脂系統的重量為基準；及b)於80-250°C之溫度與500-4000 psi之壓力下模塑步驟a)的模塑混合物中進行模塑，形成一具有想要形狀的導電板。 A graphite-vinyl ester resin reinforced conducting plate is prepared in the present in the present invention. The conducting plate can be used as a bipolar plate for a fuel cell, counter electrode for dye-sensitized solar cell and electrode of vanadium redox battery. The conducting plate is prepared as follows：a) compounding vinyl ester resin and graphite powder to form a bulk molding compound (BMC) material, the graphite powder content ranging from 70 wt% to 95 wt% based on the total weight of the graphite powder and vinyl ester, wherein 0.01-15 wt% functionalized graphene, based on the weight of the vinyl ester resin, are added during the compounding; b) molding the BMC material from step a) to form a conducting plate having a desired shaped at 80-250°C and 500-4000 psi.
