Conductive composite hydrogels based on sodium alginate (SA) and graphite were obtained by a facile method of dispersing homogeneously conductive graphite into SA hydrogel matrix formed by in situ release of Ca 2+ from Ca-EDTA, which avoids the multistep reactions and tedious purification compared to the previous work. The SA/graphite composite hydrogels exhibit reticulate and layer-type structure...
Novel polymers with synergistic wet strength and antimicrobial activity were synthesized by condensation polymerization, followed by appropriate crosslinking. 2D NMR spectra (C–H COSY) was used to characterize the molecular structure of synthesized polymer. Anionic carboxymethyl cellulose (CMC) was chosen to form polyelectrolyte polymer (PEC) complex with cationic antimicrobial-wet strength polymer...
