Glass transition of semi-crystalline PLLA with different morphologies as studi...
Picchioci, R.; Yang, Y.; Rodriguez-Perez, M. A.; Alves, N. M.; Mano, J. F.Poly(L-lactic acid) was crystallized from the glassy state at different temperatures to produce fully transformed semi-crystalline specimens exhibiting different lamellar morphologies. The materials were tested by dynamic mechanical analysis, where a Tg decrease was found with an increasing crystallization temperature. Considering a three-phase model, this tendency was related to the corresponding increase in t...
