Preparation and characterization of poly(vinyl alcohol)/poly(acrylic acid)/ polyaniline-coated multi-walled carbon nanotubes composite hydrogel |
| 초록 |
Poly(vinyl alcohol)(PVA)/poly(acrylic acid)(PAAc) hydrogel was prepared by radical polymerization and their various characteristics were studied. The conducting polyaniline-coated multi-walled carbon nanotubes were dispersed into PVA/PAAc solution to improve the electrical and mechanical properties of hydrogel. Highly conducting polyaniline-coated multi-walled carbon nanotubes were prepared by in situ polymerization. The morphology of hydrogel was characterized by scanning electron microscope and transmission electron microscope. The mechanical property of hydrogel was studied by universal testing machine. pH-dependent swelling of hydrogel was investigated in various buffer solutions under electric voltages applied. These composite hydrogel was suitable to be applied in the drug delivery system. |
