Description
技术领域
本发明涉及一种基于聚酰胺-胺树形分子的疏水涂料及其制备方法,属于疏水材料领域。
技术背景
疏水性是固体表面的一个重要性质,通常用液滴与固体之间的夹角进行衡量,即接触角。接触角越大,则固体表面的疏水性越好。通常将接触角小于90°的表面称为亲水表面,接触角大于90°的表面称为疏水表面。疏水表面因其具有许多优异的表面性能,如自清洁、防污、防腐蚀、防氧化等特性,在自清洁、流体减阻、生物医学材料等工农业生产、商业应用、国防建设领域中有着广阔的应用前景。
实现疏水表面的途径主要有两种:一是在粗糙表面上修饰低表面能物质,通常用于制备疏水表面的低表面能材料主要有聚硅氧烷、氟碳化合物及其他有机物(如聚乙烯、聚苯乙烯等);二是在疏水材料表面构建类似荷叶表面的粗糙结构,制备方法有无机纳米粒子(如TiO2、SiO2、ZnO等)修饰、激光/等离子体/化学刻蚀、模板法、静电纺丝法、溶胶-凝胶、自组装、电化学沉积及化学气相沉积等许多种类。但是在上述方法中,大部分都需要对所制备表面使用进行形貌修饰,或者对所用粒子(如二氧化硅、金属氧化物粒子等)预先进行表面处理,制备过程繁琐,成本与能耗相对较高,并且部分疏水涂料含有氟等对人体有毒有害元素,这对疏水涂料的制备和使用带来了很大的不便。因此开发一种制备简便,不含有毒元素的疏水涂料具有很大的意义。
聚酰胺-胺(PAMAM)树形分子是一种具有三维分子结构、高度支化且高度有序的树枝状化合物,它除了具有树枝化合物的共性外,还具有良好的热稳定性、水溶性、特殊的粘度与表面张力等特性,除了在生物医学、材料修饰等方面显示出巨大的应用前景外,在废水处理、石油开采、气体净化或分离等化工领域也已展现出良好的用途。但因为聚酰胺-胺树形分子内部含有大量亲水性的酰胺基团,整体呈现亲水性,如何屏蔽内部亲水基团是将聚酰胺-胺树形分子制备为疏水涂料的一个难点。因此还未有将聚酰胺-胺树形分子应用于疏水涂料的报道。
发明内容
有鉴于此,本发明的目的之一在于提供一种基于聚酰胺-胺树形分子的疏水涂料;目的之二在于提供一种基于聚酰胺-胺树形分子的疏水涂料的制备方法,该方法操作简便、不含氟元素,无需对基底提前进行表面处理。
为实现本发明的目的,提供一下技术方案:

(4)在50℃~55℃,0.098~0.1MPa真空度下,将溶液3旋蒸除去溶剂,得到一种基于聚酰胺-胺树形分子的疏水涂料;
步骤(1)所述有机溶剂a优选为甲醇、乙醇或异丙醇;
步骤(2)所述有机溶剂b优选为正己烷或环己烷;
有益效果
1.本发明的疏水涂料涂覆于复合材料基底表面后,不仅疏水性能良好,而且无需使用低表面能物质进行表面修饰或预先对所使用粒子进行修饰,可用于疏水表面的大面积制备和长期使用。
