二乙基次磷酸铝形貌调控及其在阻燃增韧环氧树脂中的应用
Morphology control of aluminum diethylphosphinate and its application for flame retardancy and toughening of epoxy resin
摘要
Abstract
This study explores the effect of various surfactants on the morphology,thermal stability,and performance of aluminum diethylphosphinate(ADP)nanoparticles in epoxy resin(EP).Using scanning electron microscopy,X-ray dif-fraction,Fourier-transform infrared spectroscopy,and thermogravimetric analysis,it was found that sodium dodecyl ben-zene sulfonate effectively suppressed nanoparticle agglomeration,while cetyltrimethylammonium bromide induced a mor-phological transformation of ADP from irregular particles to well-defined rod-like structures.This structural evolution en-hanced both the crystallinity and thermal stability of ADP.More importantly,surfactant-mediated morphology control significantly improved the dispersion and interfacial compatibility of ADP within the EP matrix.As a result,the modified composites exhibited simultaneous improvements in mechanical properties and flame retardancy.These findings demon-strate that rational selection of surfactants offers an effective strategy to tailor the morphology and functionality of ADP nanoparticles,thereby optimizing their dual role as flame retardants and toughening agents in epoxy systems.关键词
