polyacrylamide

Polyacrylamide

Polyacrylamide (IUPAC poly(2-propenamide) or poly(1-carbamoylethylene), abbreviated as PAM) is a polymer (-CH 2 CHCONH 2-) formed from acrylamide subunits. It can be synthesized as a simple linear-chain structure or cross-linked, typically using N,N '-methylenebisacrylamide.

DN hydrogels consist of a rigid first-layer network with a high crosslink density and a soft, low-crosslinked, dense second-layer network. In DN hydrogels, the rigid networks act as sacrificial bonds, the network preferentially breaks, and its fracture causes a loss of energy, thereby enhancing the mechanical properties of the DN hydrogel .
