摘要:
研究环氧树脂 /石墨微片复合导电材料的制备规律,实验发现固化剂种类、固化剂用量和固化条件对复合材料的电阻率都有影响 不同的固化剂,复合材料的电阻率不同,在最佳固化剂用量和最佳固化条件下,复合材料可获得最低电阻率 实验还研究石墨含量对环氧树脂复合导电材料的影响,发现复合材料具有渗滤效应,渗滤区石墨质量分数为 0 .0 2~ 0 .0 5,相应的电阻率约为 10 12 ~ 10 4Ω·cm .
Abstract:
With regard to the composite epoxy resin/graphite microflake conducting material, a study is made on the regular pattern of its preparation. It is found that the resistivity of this composite material is affected by variety and dosage of curing agent as well as curing condition. By studying experimentally the effect of graphite content on this composite material, it is also found that this composite material possesses percolation effect. In percolation zone, when graphite is in a quality fraction of 0.02~0.05, its corresponding resistivity is around 10 12~10 4 Ω·cm.
