中文摘要:
      采用硅烷偶联剂KH570对氧化石墨烯进行改性得到硅烷化氧化石墨烯(KGO),再通过溶液共混法制备了KGO/呋喃树脂复合材料。利用红外光谱、X射线衍射和扫描电子显微镜等方法对KGO和KGO/呋喃树脂复合材料的微观结构和相态进行了表征,并研究了KGO对呋喃树脂的热性能和力学性能的影响。结果表明,KH570成功地接枝到GO分子上得到KGO,且KGO在呋喃树脂基体中具有良好的分散性。KGO/呋喃树脂复合材料的热性能得到显著提高,其弹性模量和拉伸强度较纯呋喃树脂分别增加了384.9 MPa和6.3 MPa。
英文摘要:
      Silanized graphene oxide (KGO) was prepared from graphene oxide modified with silane coupling agent KH570, and then KGO/furan resin composites were prepared by solution blending. The microstructure and morphology of KGO and KGO/furan resin composites were characterized by FT-IR, XRD and scanning electron microscopy (SEM). The effects of KGO on the thermal properties and mechanical properties of furan resin were studied. The results show that KH570 is successfully grafted on GO. KGO has good dispersity in furan resin matrix. The thermal property of furan resin composites is enhanced markedly. Compared with pure furan resin, the elastic modulus and tensile strength of KGO/furan resin composites are improved by 384.9 MPa and 6.3 MPa, respectively.
