Coating materials comprising polymeric particles in a geometrically ordered array are disclosed. The particles can be formed from materials having different glass transition temperatures; this allows for phase segregation between areas of different glass transition temperatures within each particle. Typically, at least 50 percent of the particles will form a hexagonal array, capable of exhibiting Bragg diffraction. Because the particles within the array do not coalesce to any appreciable extent, significant surface area is provided by the present coating materials. Thus, the present materials have particularly good sound deadening properties. Substrates coated with the present materials are also disclosed, as are methods for inhibiting sound transmission through a substrate using these coatings.
本发明公开了由几何有序排列的聚合物颗粒组成的涂层材料。这些颗粒可以由具有不同
玻璃化转变温度的材料形成;这样就可以在每个颗粒内不同
玻璃化转变温度的区域之间进行相分离。通常情况下,至少 50% 的颗粒会形成六角形阵列,能够显示布拉格衍射。由于阵列内的颗粒不会明显凝聚,因此本涂层材料具有很大的表面积。因此,本材料具有特别好的消音性能。还公开了涂有本材料的基底,以及使用这些涂层抑制声音通过基底传播的方法。
