Thermo and electro-responsive release behavior of PVA/PNIPAAm/MWCNT/PPy nanocomposite hydrogels |
| 초록 |
The poly(vinyl alcohol) (PVA)/poly(N-isopropylacrylamide) (PNIPAAm)/multi-walled carbon nanotube (MWCNT)/ poly(pyrrole) (PPy) nanocomposites were prepared by in situ radical polymerization. PPy was uniformly coated on MWCNTs resulting in the improvement in both mechanical and conductive properties of nanocomposite hydrogels which were evaluated as electro and thermo-responsive drug delivery systems. The morphologies and thermal behaviors of nanocomposite hydrogels were investigated by scanning electron microscope and thermogravimetric analyzer, respectively. The thermo-dependent swelling and releasing properties indicated that the incorporation of MWCNT-PPy hybrids was responsible for the faster response of the nanocomposite hydrogels. |
