Elasticity properties such as stress strain and compressive elastic modulus S of these composite gels were studied in various kappa C content and at several temperatures. The content and temperature dependence of the compressive elastic modulus S of the swollen PAAm-kappa C composite gels due to volume phase transition were produced by using tensile testing technique. It is understood that the compressive elastic modulus was found to decrease up to 1 (w/v)% of kappa C and then increase by increasing kappa C contents at constant temperatures. The composite preserves the ability to undergo the volume phase transition and its compressive elastic modulus is found to be strongly dependent on the kappa C content and temperature. It is observed that the compressive elastic modulus increased when temperature is increased up to 40 degrees C and then decreases below this temperature for all composite gels. However PAAm-kappa C composite gel presented lower values for the compressive elastic modulus showing a minima at 40 degrees C for 1 (w/v)% of kappa C content gel.eninfo:eu-repo/semantics/openAccessArticle3313353128WOS:00036635670001710.12693/APhysPolA.128.3312-s2.0-84947813365N/AQ4
