As important functional fillers, liquid crystals (LC) are widely used to fabricate various liquid-crystalline polymer composites because they combine the basic properties of conventional polymers with those of LC . For example, Finkelmann et al. have prepared an LC shape memory elastomer, which can be stimulated with photo-illumination by incorporating azo groups into the LC . Additionally, Samit V. Ahir et al. have synthesized a new tri-block copolymer with a large central block composed of main-chain nematic units to retain the director alignment, and the resulting LC copolymers show a significant two-way SME . These previous studies have primarily focused on liquid crystalline elastomers or well-defined LC copolymers. Recently, we have developed a facile and versatile method for the preparation of LC-SMPCs. Several series of LC-SMPU composites with both LC properties and shape memory properties were successfully prepared by mixing various SMPU matrixes with 4-n-hexadecyloxybenzoic acid (HOBA) . Our recent investigations also demonstrated that supramolecular LC-SMPCs based on 4-octyldecyloxybenzoic acid (OOBA) and the supramolecular SMPUs exhibit triple-SMEs and quadruple-SMEs . It was thus proposed that the LC-SMPCs might be good candidates for many potential applications in the field of artificial intelligence. In order to further understand the LC-SMPCs completely and promote their future applications, the significant effects of HOBA and OOBA mesogens on the glass transition and crystal-melting transition of the soft segments have been reported in the previous HOBA-SMPU and supramolecular OOBA-SMPU systems. However, the effect of LC mesogens on the hard segment of SMPU remains unclear. We would like to present a series of investigations about the LC-SMPCs with different LC mesogens in this study.
