Inside Front Cover: In article number 1900316, Jichun You and co‐workers provide an efficient strategy to prepare poly(L‐lactic acid) (PLLA) with high ductility and transparency, in which tiny amount of polyvinylidene fluoride (PVDF) and compatibilizers are added to the PLLA matrix. The left part is the PVDF/PLLA blend without compatibilizers while the right part is the PVDF/PLLA blend with compatibilizers. The PVDF/PLLA blends containing compatibilizers exhibit better mechanical and optical properties.

通过掺入少量的PVDF和增容剂来制备具有高延展性和透明度的PLLA

内部封面：在编号1900316中，吉春友和他的同事提供了一种有效的策略来制备具有高延展性和透明度的聚（L-乳酸）（PLLA），其中少量的聚偏二氟乙烯（PVDF）和增容剂是添加到PLLA矩阵。左侧是不含增容剂的PVDF / PLLA混合物，右侧是含增容剂的PVDF / PLLA混合物。含有增容剂的PVDF / PLLA共混物表现出更好的机械和光学性能。
