Interchain interactions. The polymer chains can be free to slide past one another (thermo-plastic) or they can be connected to each other with crosslinks (thermoset or elastomer).
链间的相互作用：聚合物的分子链可以自由地彼此滑动(热可塑性)或通过交键互相连接(热固性或弹性)。

Polymer nanocomposites are formed from blends of nanometer sized fillers with either thermoset or thermoplastic polymers.
