20.500.12556/DiRROS-28826 Mechanical anisotropy in compressive-stress shape-programmed liquid crystal elastomers and polymer-dispersed liquid crystal elastomer composites Polymer-dispersed liquid crystal elastomer composites (PDLCEs) combine the thermomechanical capabilities of liquid crystal elastomers (LCEs) with the softness of a silicone matrix. The high-temperature persistent glass phase in LCEs allows preservation of the instilled deformations during thermal cycling, leading to reprogrammable shape-memory in both LCEs and PDLCEs. This provides a unique opportunity to study mechanical properties within a single shape-programmed specimen by imposing different mesogen configurations or particle geometries, without the need for repeated synthesis. We specifically focus on compressive programming, which induces transverse mechanical anisotropy and a mesogen configuration with a negative order parameter. Directional stress–strain and thermomechanical tests reveal that, despite the elastic matrix, PDLCEs retain mechanical properties comparable to pure LCEs, highlighting the role of mechanical anisotropy together with inclusion alignment and geometry. The degree of mesogen ordering is evaluated in LCEs, while a modified Halpin–Tsai model captures the mechanical response of PDLCEs. mehanical anisotropy mehanska anizotropija true false true Springer Nature Združeno kraljestvo Angleški jezik Slovenski jezik © The Author(s) 2026 Neznano 2026-04-08 13:50:00 2026-04-08 13:50:01 2026-04-09 03:51:23 0000-00-00 00:00:00 2026 0 0 Nasl. z nasl. zaslona; Soavtorja iz Slovenije: Luka Racman Knez, Andraž Rešetič; Opis vira z dne 7. 4. 2026; str. 1-11 Vol. 2, article no. 8 2026 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2025-08-26 2026-02-21 2026-04-01 53 3059-3263 10.1038/s44431-026-00022-z 274372611 https://www.nature.com/articles/s44431-026-00022-z 1 1d142f88-3341-11f1-b941-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=42951 RAZ_Lavric_Marta_2026.pdf RAZ_Lavric_Marta_2026.pdf 1 860CFEAA7835571D4BB472E3E58F432C fc5c071252c71f1859e7b17ac0b834ab772fa93613c67033bdf0e606dcb5ad42 551447c7-3341-11f1-b941-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=42952 Institut Jožef Stefan 0 0 0
