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 composites are measured by compressive test revealing a decrease in the shear modulus and toughness of the composites above 8 A mu l of GO by increasing GO content.eninfo:eu-repo/semantics/closedAccessGraphene oxideElasticityToughnessSwellingAcrylamideArticle14311439475WOS:00042737300000610.1007/s00289-017-2101-42-s2.0-85053418615N/AQ2
