INTERPENETRATED POLYMER LAYER

摘要

Structures having an interpenetrated polymer layer are described. The interpenetrating layer (230) comprises a mixture of a first component (211) and a second component (212), wherein the concentrations of the first component and the second component vary inversely across the thickness of the interpenetrating layer. Both interpenetrated surface layers (210, 220) and interpenetrated bonding layers (230) are described. Methods of forming an interpenetrated layer are also disclosed.
