The dispersion of particles are also related to the interactionbetween nanosilver and polymer. Nanosilver dispersed well in PS, while form larger branchedclusters in PMMA, and polymers could prevent nanoparticles from aggregation. The interaction between nanosilver and polymers depends on the properties of polymers and treatment. XPS results indicated that no obvious interaction between nanosilver and PS was foundbefore and after heat treatment; for AS matrix, there exists a interaction between nanosilver and AN,moreover AN on the nanosilver surface could cyclize and lose N after heat treatment at 150℃ for1h; for PMMA matrix, there exists a interaction between nanosilver and O atoms, heat treatment at150℃ for 1h could lead to the reaction between Ag, S and O in the interlayer of composite andchange the interface interaction.

纳米银粒子的加入改变了聚合物体系对激光能量的吸收和转换方式，导致其激光离解方式的变化，通常此种粒子会促进聚合物的炭化，且在界面可能有诱导石墨化的作用；而银粒子自身的离解及其对基体激光离解的作用都受两相的界面相互作用的影响，即与聚合物基体的性质、后处理等有关，热处理后两相界面的变化对PS和AS体系的炭化影响不大，但PS体系中银团簇的最大原子聚集数减小；而对PMMA体系则基本上消除了激光炭化。
