Effect of Nano and Hybrid Fillers on Shape-Memory Polymers Properties

Abstract

Shape-memory polymers (SMPs) are smart polymeric materials with the ability to come back from a deformed state to their original shape induced by an external stimulus. These materials can pile a temporary shape, restored to their original shape upon application of an external stimulus, for instance, heat. Especially, shape-memory polymer composites (SMPCs) can be established into multifunctional materials actuated by various methods, such as thermal-induced, electro-activated, light-induced, and magnetic-actuated. Due to its unique stiffness and shape-changing functionality; to be applied both to study bone mechano-biology and to address limitations associated with current bone repair techniques. SMPs have great prospective in the clothing and textiles industries due to their similarity to textile structures, as well as uses in the production of medical devices, micro-electromechanical systems, biomaterials, SMP foams, automobile actuators, self-healing composite systems, etc. To expand the space use of SMPs, the SMPCs were made up, either to develop the mechanical properties or to incorporate more stimulus methods. Furthermore, a shape recovery test and Dynamic Mechanical Analysis (DMA) controls the mechanical properties. Recently developed nanocomposites and laminated hybrid composites aimed to enhance shape-memory and recovery stress. In this book chapter, alongside the effect of nano and hybrid fillers on shape-memory polymers properties, we have focused on the synthesis, properties of SMPs, SMP composites, EA-SMPs, controlled behavior of composite material (CBCM) and their applications, and concluded with recent progress and prospects. A certain emphasis on how the incorporation of micro/nanofillers and particles or fibers do affect the SMP matrices, which is intentionally carried out to improve the mechanical properties and their related shape-memory features of various types of shape-memory polymers. Shape-memory polymer-based flexible electronic devices (SMPFED) fabrication technologies are used for printing electronic technology and 4D printing. © The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG 2022, corrected publication 2022.
