Publisher and Date:(Avestia Publishing, 2019)Graphene oxide (GO) is a two dimensional carbon material with similar one-atom thickness, and is a light material having extremely high strength and thermal stability . Thus, GO is an efficient filler for the enhancement of the electrical, mechanical and thermal properties of composite materials . We focused on GO as a nanofiller in polyacrylamide hydrogels and PAAm-GO composites to investigate the effect of temperature and graphene oxide on the swelling. Polyacrylamide (PAAm) hydrogels have ...
Mechanical properties of graphene oxide-polyacrylamide composites before and after swelling in water Authors:
Publisher and Date:(Springer, 2018)Polyacrylamide (PAAm) hydrogels have been proposed for use as promising biomaterials in biomedical and tissue engineering but their poor mechanical and water-retention properties have hindered their development. Graphene oxide (GO) an excellent nanofiller was added to PAAm to produce mechanically strong GO-PAAm composites. The free radical crosslinking copolymerization method was used with GO content varying in the range between 5 and 50 A mu l of GO. The mechanical properties of the GO-PAAm ...
