Abstract
Composites formed from Polyacrylamide (PAAm)-Multiwalled carbon nanotubes (MWNTs) were prepared via free radical crosslinking copolymerization with different amounts of MWNTs varying in the range between 0.1 and 50 wt%. The temperature variations of the elastic modulus, G of the PAAm-MWNT composite due to volume phase transition were measured by using tensile testing technique. The composite preserves the ability to undergo the volume phase transition and its elastic modulus and toughness (T) are found strongly dependent on temperature. It is observed that elastic modulus increased when temperature is increased from 30?C to 60?C. Toughness, however presented the reversed behavior versus temperature compare to the elastic modulus.
