, 2005 原子力显微镜(AFM)是在扫描隧道显微镜(STM)基础上发明的又一种纳米级高分辨率显微技术,目前已在高分子领域获得了广泛的应用.AFM无需对样品进行任何预处理即可对各种材料进行微观区域的表面形貌及机械性能探测,或者直接进行纳米操纵.本文则从表征聚合物聚集态、物理性质 ...

Study on intumescent steel structure fire-retardant coatings [PDF]
, 2003 火灾是当今世界上常发性灾害中发生频率较高的一种灾害，在世界各国的火灾事故中，建筑物火灾居于首位；为减少人们在火灾中的危险，建筑业中最简便且最有效的一项安全措施就是采用功能型涂料——防火涂料。近年来，大跨度和超高层建筑物均广泛采用钢结构。钢材虽是不燃物，但导热系数大，随着温度的升高，钢材的机械力学性能迅速下降（失效临界温度540℃）；未加防火保护的钢结构，遭遇火灾只需10多分钟，自身温度就可达700℃以上，在纵向压力和横向拉力作用下，钢结构扭曲变形、跨塌损毁。要满足1～3小时的耐火极限要求 ...
