The electromagnetic wave absorption and mechanical properties of recycled cement mortar modified by recycled concrete powder and CNTs/Nano-Fe 3 O 4

This study prepared electromagnetic wave (EMW)-absorbing recycled cement mortar using recycled concrete powder (RCP), cement, natural river sand, and a CNTs/Nano-Fe3O4 composite absorber. The effects of RCP content and CNTs/Nano-Fe3O4 dosage on phase composition, microstructure,...

Controlling Dual Reflection Bands of Cholesteric Liquid Crystal Polymer Network Films via Photoisomerization and Polymerization-Induced Molecular Migration

Abstract Cholesteric liquid crystal polymer network (CLCN) films featuring dual reflection bands have emerged as promising materials for decorative and anticounterfeiting applications, owing to their unique composite structural colors. Currently, these films are commonly fabricat...
