Title: (EN) Low-density gel article and method for producing low-density gel article
(ZH) 低密度凝胶体及低密度凝胶体的制造方法
Abstract: front page image
(EN) The low-density gel article has, on the surface thereof, a coating layer constituted by a polymerized monomer polymerizable in a gas phase. This low-density gel article has improved mechanical strength. The low-density gel article is, for example, an aerogel or a xerogel. The low-density gel article may, for example, be a monolithic article such as a sheet, or particles. The monomer polymerizablein a gas phase is, for example, at least one monomer selected from olefins, styrene, styrene derivatives, (meth)acrylic acid, (meth)acrylic acid esters, p-xylylene, and p-xylylene derivatives.
(ZH) 本申请的低密度凝胶体在表面具有包含气相聚合性单体的聚合物的涂层。本申请的低密度凝胶体提高了机械强度。低密度凝胶体例如为气凝胶及干凝胶。低密度凝胶体例如可以为片状等整体式多孔体或粒子。气相聚合性单体例如为选自烯烃、苯乙烯、苯乙烯衍生物、(甲基)丙烯酸、(甲基)丙烯酸酯、对二甲苯及对二甲苯衍生物中的至少1种。
