Preparation and performance of dynamic boronate-crosslinked flame-retardant phenolic aerogels
摘要
Abstract
A boron-containing bisphenol precursor molecule with dynamic reversible coordination properties was designed to construct high-performance recyclable flame-retardant phenolic aerogels(BPF)via a sol-gel process,using water as the sole green solvent.The microstructure,thermal insulation,flame retardancy,and degradability of BPF were system-atically investigated by means of mercury porosimetry,thermal conductivity analyzer,universal testing machine,limiting oxygen index,cone calorimeter,and nuclear magnetic resonance spectroscopy.The results demonstrated that,com-pared with pure phenolic aerogels derived from phenol precursors,BPF exhibits significantly enhanced comprehensive performance:the porosity is increased by 110.4%,the thermal conductivity is reduced by 48.6%,the heat release is remarkably decreased by 32.4%,and the limiting oxygen index reaches 34%.Meanwhile,the compressive strength is significantly improved by 70%,and the aerogel maintains structural integrity and high mechanical strength even under 50%compressive deformation.After disposal,the stimulus-responsive dissociation characteristic of the boron-contain-ing crosslinked structure enables rapid deconstruction and recycling of the phenolic aerogels,endowing the material with excellent environmental sustainability.关键词
