合成了甲基丙烯酸二甲氨基乙酯马来酸盐离子液体(DMAEMA-MA),通过共混法制备了DMAEMA-MA改性酚醛树脂和DMAEMA-MA改性酚醛树脂/石墨烯复合材料。探讨了DMAEMA-MA含量对DMAEMA-MA改性酚醛树脂热稳定性、力学性能及导电性能的影响。结果表明:DMAEMA-MA的添加显著提高了酚醛树脂的冲击强度,而弯曲强度降低。DMAEMA-MA的添加提高了酚醛树脂的电导率。在DMAEMA-MA改性酚醛树脂中添加石墨烯显著提高复合材料的导电性能。
Ionic liquid dimethylaminoethyl methacrylate maleate (DMAEMA-MA) was synthesized.DMAEMA-MA-modified phenolic resin (PF) and PF/graphene were prepared by blending method.The effect of DMAEMA-MA content on the thermal stability,mechanical properties and electrical conductivity of DMAEMA-MA-modified PF was investigated.As a result,the addition of DMAEMA-MA can effectively improve the impact strength of PF,but the bending strength was significantly reduced.The electrical conductivity of PF was improved with the addition of DMAEMA-MA.The electrical conductivity of DMAEMA-MA-modified PF increased significantly by the addition of graphene.
