我把你的中文摘要也进行了加工,只是建议性的修改。
本文是关于氧化石墨烯(GO)与PPC 共混物的性能改良。GO可以增加PPC的强度,韧性和应用范围。文献中,用马来酸酐封端过的PPC不会发生降解反应的同时,提高了热稳定性和力学性能。
实验结果表明:向M-PPC加入0.1%GO形成的共混溶液的生物降解没有受到影响,明显的提高了力学强度和和韧性。当GO的比例升高时,强度成正比关系。
红外光谱分析仪(FTIR)、原子力显微镜(AFM)、扫描电子显微镜(SEM)和动态粘弹谱仪(DMA)表明:共混物力学性能的提高主要是由于共混后的M-PPC与GO之间界面相互作用提高的结果,且共混物中两者并没有什么相互反应。GO在共混物中形成了网络的结构,起到了填料的作用。使得M-PPC的力学性能的到了很大程度上的提升。本文所研究的共混改性方法,能够有效地改进可降解聚合物PPC的的性能,使其力学性能达到工业要求,从而扩大其应用范围。
This paper focused on the mixture of graphene oxide (GO) and PPC.PPC to which added GO strengthens intension and toughness, and increasing the range of applications.Performance of PPC capping a small amount of maleic anhydride(M-PPC) can significantly improved in the document.
M-PPC can prevent the degradation reactions, and increase the thermal stability and mechanical properties.
The results show that: the mixture solution of M-PPC formed by adding 0.1% GO is biodegradable, and strengthens the intension and toughness. When percentage of GO increases, the intensity proportional.
FTIR,AFM,SEM and DMAshowed that improvement of performance was due to strengthen interaction of interface. The network of GO and M_PPC play the performance-enhancing role.
The method of this article significantly improves the performance of PPC and application, and meet the requirements of industrialization. |
