功能化氧化石墨烯改性酚醛树脂微发泡复合材料的制备与性能
Preparation and properties of functionalized graphene oxide modified phenolic resin microfoam composites
摘要
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 spectros-copy 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 mi-crofoamed composites.关键词
