湿法混炼氧化石墨烯/天然橡胶复合材料的性能研究

本文通过湿法混炼的方法,利用高压喷射装置制备出氧化石墨烯(GO)/天然橡胶(NR)复合材料并对其各种性能进行了研究。结果表明：随着GO用量的增加,GO/NR复合材料的力学性能,导热性能均明显提高,在用量为2份时,性能相对最佳；SEM结果显示,在GO为2份时分散较好；加入GO后,储能模量G′明显增大,超过2份时,payne效应变化不大；加入GO后,损耗因子tanσ略有减小,随着GO用量的增加,tanσ变化不大。;In this paper, the composites of grapheme oxide and natural(GO/NR) are preparated use High-pressure injection device by the method of wet mixing and all kinds of properties are researched. It is showed that ：With the increase of the amount of GO, the mechanical properties and thermal conductivity of composites of GO/NR are obviously increase, Relative to others , the properties are best when the dosage of GO add to 2 phr; SEM show that GO dispersed well when GO is added to 2phr; the storage modulus is significantly increasing after GO is added , payne effect have no significantly chance when the dosage of GO exceed 2 phr; Loss factor tanσ decreases slightly, With the increase of the amount of GO, tanσ have no significantly chance
