The mechanical properties of swollen PAAm-MWNT composites were characterized by the tensile testing technique. A small content of embedded nanotubes dramatically changes the compressive elastic modulus of the composites. Compressive elastic modulus dramatically increases up to 1wt% MWNT on increasing nanotube content and then decreases presenting a critical MWNT value indicating that there is a sudden change in the material elasticity. The critical exponent y of elasticity below the critical MWNT content 1 wt% is found to be 0.58 which is consistent with the suggestions of percolation in the superelastic percolation network for PAAm-MWNT composite.eninfo:eu-repo/semantics/openAccessAcrylamideMultiwalled-carbon nanotubesHydrogelMechanical propertiesArticle553564685WOS:00030442440000910.1080/01411594.2011.6343332-s2.0-84862225296N/AN/A
