摘要
Conductive biohydrogel received prominent application in the diverse field. Hydrogel based on biopolymer is generally biocompatible and degradable but exhibiting poor conductivity. To enhance the conductivity of biohydrogel, composite of bioplomer and synthetic polymer are preferred. This work aims to prepare such composite for the augmentation of conductivity of biohydrogel. Gum Ghatti (GG), a natural biopolymer, was grafted with polyacrylic acid and subsequently cross-linked to form a hydrogel. The synthesized hydrogel was then infused with oxidized multiwalled carbon nanotubes (-o-MWCNTs). The materials underwent comprehensive characterization using techniques, such as FT-IR, XRD, SEM, and TGA-DTA. The grafted GG demonstrated a synergistic blend of biopolymer and polyacrylic acid (AA) properties. The hydrogel's electrical conductivity was systematically investigated at varying loadings of -o-MWCNTs within the GG-cl-P(AA) matrix. As the loading of -o-MWCNTs increased from 10 to 30 mg, there was a notable enhancement in electrical conductivity. However, at higher loading amounts, the electrical conductivity exhibited a subsequent decline.
