Abstract

Fabricating conductive hydrogels (CHs) which is tough, stretchable and electrically conductive at the same time can be challenging. Herein, a double network (DN) hydrogels of different compositions of polyacrylamide (PAAm) and poly (sodium 4-styrenesulfonate) (PSS)/poly (diallyl dimethyl ammonium) (PDADMA) will be freeze-dried and coated with PPy by oxidative chemical vapor deposition (oCVD). The effect of freeze-drying and oCVD PPy coating on the DN hydrogels were studied by conducting ATR spectroscopic analyses, water content analyses and cyclic compression tests. Furthermore, the swelling behaviour of the uncoated DN hydrogels were also performed. The results indicate that freeze-drying does not disrupt the physical and chemical structure of the DN hydrogels and an oCVD PPy coated DN hydrogel with a strong and tough mechanical property was successfully synthesized. The results from the swelling studies shows that DN hydrogels are pH- and salt-sensitive. The DN hydrogels also exhibited pH-swelling reversibility. These characteristics may lead CHs to be a promising material to be used in biomedical applications.
