Research data for the publication 'Poly(L-lactide) liquid crystals with tailor-made properties toward a specific nematic mesophase texture'

Research data for publication funded by the GREEN-MAP project. Includes DSC, X-ray, AFM, POM and SEM analyzes. The paper presents research on the liquid crystal (LC) properties of poly(L-lactide) (PLLA), which was prepared with the use of a press in order to develop a comprehensive characterization of (bio)degradable polyesters obtained by pressing. Pressed PLLA films show a unique ability to self-assemble into a nematic mesophase under the influence of mechanical pressure, temperature and appropriate time. It has also been shown that a chiral nematic mesophase can be obtained by introducing a fine powder into a polymer matrix. Based on the research conducted, it was proved that the pressed films have a stable chiral nematic mesophase, which can persist for years at ambient temperature. Various textures were obtained, including the colored planar texture of the chiral nematic mesophase, and the blue phase, first time described in plain PLLA.
