文摘
- •
Poly(N-isopropylacrylamide) hydrogels were prepared at various temperatures.
- •
Hydrogels showed significant variation in appearance and microstructures.
- •
Swelling and deswelling of hydrogels were studied in aqueous salt solutions.
- •
Hydrogels showed surface pattern formation during deswelling.
- •
Pattern formation depended on gel preparation temperature and salt concentration.
