    摘要： 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.
