Morphology formation during the nonisothermal thermally?induced phase separation ( <scp>TIPS</scp> ) process

In high-viscosity polymer solutions and blends, temperature variations during the quench process of thermally-induced phase separation (TIPS) influence dynamics thermodynamics separation. Hence, this study aims to investigate impact on morphology formation TIPS process. First, temporal is investigated by coupling a transient heat conduction model Cahn–Hilliard equation, results are compared with isothermal Next, inspected applying from two opposite sides sample same different temperatures through Fourier transfer equation equation. The enthalpy demixing competition between mass also evaluated. It confirmed that alone have significant addition, quenching system both leads anisotropic formation, which affected rate, temperature, solution viscosity, demixing. Upon sides, types morphologies droplet sizes were formed as result difference in cooling rates sides. Employing induced shallow effect deep side due fact moved toward lowest system, led distinctive structure.
