Calorimetry method is a method that can be used to characterize physical properties of material. This experiment used Differetial Scanning Calorimetry (DSC) to characterize sampel calorimetrically. Four samples of Main-Chain Liquid Crystal Elastomer (MC-LCE) with different crosslinker concentration, namely 8%, 12%, 14% and 16% were tested. All samples were analyzed using DSC with same heating and cooling process. The thermogram from analyzed samples then calculated to obtain information about enthalpy and phase transition point from heating and cooling process. The result showed that the enthalpies tend to decrease with increasing crosslinker concentration, whereas the phase transition temperatures tend to decrease with increasing crosslinker concentration.
