The melting of poly (l-lactic acid) [PDF]
European Polymer Journal, 2018 Abstract The effect of crystallization temperature and time on the melting of a stereo-copolymer of l -lactic acid has been measured using differential scanning calorimetry and hot stage microscopy. The temperature of the last trace of crystallinity increased with time and temperature.

Development of Poly(l-Lactic Acid)-Based Bending Actuators [PDF]
Polymers, 2020 This work reports on the development of bending actuators based on poly(l-lactic acid) (PLLA)/ionic liquid (IL) blends, through the incorporation of 40% wt. of the 1-ethyl-methylimidazolium bis(trifluoromethylsulfonyl)imide ([Emim][TFSI]) IL. The films, obtained by solvent casting at room temperature and 50 °C, were subjected to several post-thermal ...
