Supercritical carbon dioxide has unique properties and valuable potential for processing many materials but has small solvent power to dissolve polylactide. Small amount of solvent could increase solvent power of supercritical carbon dioxide. Stereocomplex formation is one kind of method that can be used to increase the thermal properties of polylactide. Stereocomplex of poly D-lactide/poly L-lactide will be exclusively formed in supercritical carbon dioxide cosolvent system. At this work, variables on stereocomplex formation such as solubility, solvent effect, and effect of process parameters (temperature, pressure, and time) are discussed |
