摘要: Well-dispersed copper nanoparticles were fabricated using poly(vinyl alcohol)/polyacrylamide interpenetrating polymer networks (PVA/PAAm IPNs) as a nanoreactor template. The synthesis of the IPNs hydrogels was achieved in presence glutaraldehyde and N,N′-methylene-bis-acrylamide. resulting PVA/PAAm/Cu nanocomposite characterized, swelling mechanical properties investigated. results indicated that had spherical shape with size range from 10 to 20 nm. complexation PVA PVA/PAAm Cu2+ played an important role avoiding aggregation providing particle distribution controllability stability. Although capacity slightly lower than control, they better compression properties. water uptake can be easily tuned by changing component ratios meet requirements specific applications, such drug controlled release or tissue engineering.
