摘要/Abstract

摘要： 以N-氨乙基哌嗪(AEP)和二氧化碳为原料,制备发泡剂B-AEP,并将其负载在氧化石墨烯(GO)表面,成功制备出集成核、发泡、增强为一体的功能化氧化石墨烯粒子(GO@B-AEP),采用一步法受限发泡制备出功能化氧化石墨烯改性酚醛(GO/PF)微发泡复合材料。采用红外光谱和扫描电子显微镜(SEM)研究了GO@B-AEP的结构;采用万用试验机和邵氏硬度计研究了GO添加量、表观密度以及发泡剂含量对GO/PF微发泡复合材料力学性能的影响;采用SEM对微孔结构与孔径分布进行了分析。结果表明:当GO添加量为0.4wt%时,GO/PF力学性能最佳,同时热稳定性最佳;当表观密度为1.0 g/cm³时,泡孔质量最佳;当发泡剂含量为1.5wt%时,泡孔形状与尺寸较好,GO/PF微发泡复合材料的力学性能得到显著提升。

Abstract: The foaming agent B-AEP was synthesized using N-aminethylpiperazine (AEP) and carbon dioxide as raw materials, and subsequently loaded onto the surface of graphene oxide (GO). This resulted in the successful preparation of functional graphene oxide particles with integrated nucleus, foam and reinforcement, known as GO@B-AEP. Furthermore, functional graphene oxide modified phenolic (GO/PF) microfoamed composites were prepared through a one-step limited foaming method. The structure of GO@B-AEP was characterized using infrared spectroscopy and scanning electron microscopy (SEM). The effects of varying amounts of GO addition, apparent density, and foaming agent content on the mechanical properties of GO/PF microfoamable composites were investigated using a multipurpose testing machine and Shore hardness tester. Additionally, SEM analysis was conducted to analyze the micropore structure and pore size distribution. The results demonstrate that optimal mechanical properties and thermal stability are achieved when the dosage of GO is 0.4wt%. Similarly, superior pore quality is observed at an apparent density of 1.0 g/cm³. Moreover, when the content of foaming agent is set at 1.5wt%, improved shape and size characteristics are observed in the pores along with significantly enhanced mechanical properties in GO/PF microfoamed composites.
