| Abstract: | A novel poly (methacrylic acid)/multi-walled carbon nanotube( PMAA /MWCNT) hybrid hydrogel was prepared based on by means of a in situ free radical cross-linking polymerization. The structures and swelling properties of these hydrogels with various contents of MWCNTs were investigated. The experimental results revealed that PMAA/MWCNT hybrid hydrogels show a Stronger pH-sensitivity and higher swelling properties than pure poly(methacrylic acid) (PMAA) hydrogels by adjusting or modulating the concentration of the MWCNT. |
