Influence of biaxial stretching mode on the crystalline texture in polylactic acid films

Effect of the simultaneous biaxial stretching on the structural and mechanical properties of PLA, PBAT and their blends at rubbery state

“…Different crystalline peaks were also detected and may corresponded to (203 & 113), (206 & 116) and (0 0 10) as shown in Fig. 9 [30].…”

Isotropically small crystalline lamellae induced by high biaxial-stretching rate as a key microstructure for super-tough polylactide film

“…Ou and Cakmak [29] compared the microstructures of BOPLA films, produced via a stretching rate of 3 mm/s and draw ratios of 2 Â 2 to 4 Â 4 (l MD Â l TD ) at 70 C under varied stretching modes. The analyses by WAXD images and pole figures led to an understanding of the microstructure in terms of (i) in-plane isotropy of (200/110) diffractions with the degree of crystallinity (Х c ) 15% and (ii) in-plane anisotropy with Х c 20% for simultaneous and sequential BOPLA, respectively.…”

Synthesis of Polylactide-b-Poly (Dimethyl Siloxane) Block Copolymers and Their Blends with Pure Polylactide

“…However, there is still a great need to improve other properties, such as the thermal and mechanical properties to increase the scope of applications in the biomedical or environmental plastics fields. One of the most effective methods for enhancing the thermal and mechanical properties of PLA is its copolymerization with other monomers or polymers [19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37][38].…”
