Fabrication of a mechanically tough and strong SiO2@EPOSS modified novolac phenolic network by simultaneously improving its crosslinking inhomogeneity and crosslinking density

Simultaneously improving mechanical strength and toughness of thermosetting polymer nanocomposites remains a great challenge even though massive efforts have been made by controlling the aggregation and interface interaction of nanoparticles. In fact, crosslinking inhomogeneity and crosslinking density of thermosetting polymer nanocomposites can also profoundly affect the competing mechanical properties. Due to their conflicting influence on the...
