埃洛石纳米管的表面改性处理方法
摘要：
本发明涉及纳米复合材料的制备方法，特别是涉及用硅烷偶联剂改性埃洛石纳米管的方法，以及由该方法获得的改性埃洛石纳米管与环氧树脂混合制备的环氧树脂纳米复合材料。本发明的埃洛石纳米管的表面改性处理方法是将硅烷偶联剂加入到含有酸化的埃洛石纳米管的悬浮液中，通过硅烷偶联剂上的可水解的X基团与埃洛石纳米管表面片层上的羟基之间进行缩合反应，得到经硅烷偶联剂改性处理的内腔和外表面接枝硅烷偶联剂的改性埃洛石纳米管。将改性埃洛石纳米管与环氧树脂混合制备得到环氧树脂纳米复合材料，该环氧树脂纳米复合材料能够获得理想的力学性能和热性能。
摘要（英）：

The invention relates to a method for preparing a nanocomposite and particularly relates to a method for modifying a halloysite nanotube with a silane coupling agent and an epoxy resin nanocomposite prepared by mixing the modified halloysite nanotube obtained by the method and epoxy resin. The surface modification treatment method of the halloysite nanotube, which is disclosed by the invention comprises the following steps of adding the silane coupling agent into a suspension containing the acidified halloysite nanotube and carrying out condensation reaction on a hydrolyzable X group on the silane coupling agent and a hydroxy group on the lamella on the surface of the halloysite nanotube to obtain the halloysite nanotube which is modified by the silane coupling agent and of which an inner cavity and the outer surface are grafted by the silane coupling agent, and mixing the modified halloysite nanotube and epoxy resin to prepare the epoxy resin nanocomposite. The epoxy resin nanocomposite can obtain the desired mechanical properties and thermal properties.
