摘要: Abstract Temperature sensitive PolyNIPAAm hydrogels in the form of rod were prepared from binary system NIPAAm/water and ternary NIPAAm/Bis/water by γ-irradiation with 60 Co source at room temperature, respectively. The had obvious temperature sensitivity (LCST is about 35.0 °C) suitable mechanical properties. incorporation cross-linking agent, N, N′-methylene-bisacrylamide (Bis), into monomer/water reduced gelation dose. maximum swelling ratio was decreased increasing dose or Bis. diffusion behavior water obtained this work investigated. In addition, drug delivery fluoro uracili (Fu-5)
