ABSTRACT In order to study heat transfer in cellulose cork, Novolac aerogel with features including large surface area and low-thermal conductivity was used as filler. Novolac colloids result in cork micropores packing and minimize convection heat transfer. Novolac aerogel was synthesized through sol–gel at saturated vapor of solvent atmosphere. A small amount of Novolac enables cork nanocomposites to have low-thermal conductivity, diffusivity, and high-thermal stability (reduction about 39%, 45%, and improvement of 30°C, respectively). Ultimately, in order to improve aerogel/cellulose cork nanocomposites ablation, samples have been coated with resole resin-filled graphene oxide.

酚醛清漆气凝胶纳米结构和纤维素软木对轻质隔热罩的热性能和烧蚀性能的增强：关于省略热对流

摘要 为了研究纤维素软木中的传热，使用具有大表面积和低导热率的酚醛清漆气凝胶作为填料。酚醛清漆胶体导致软木微孔堆积并使对流热传递最小化。酚醛清漆气凝胶是在饱和溶剂气氛下通过溶胶-凝胶合成的。少量酚醛清漆可使软木纳米复合材料具有低导热性、扩散性和高热稳定性（分别降低约 39%、45% 和提高 30°C）。最终，为了改善气凝胶/纤维素软木纳米复合材料的消融，样品已涂上填充有甲阶酚醛树脂的氧化石墨烯。
