Smart shape memory materials

摘要

Shape memory materials(SMMs)are smart materials that can remember and recover substantial programmed deformation upon activation and exposure to an external stimulus such as temperature,magnetic field,electric field,pH value,and UV light.They can be used comfortably with human skin because of their low weight and softness.The application of both alloys and polymers of SMMs in textile has gained momentum to shape memory smart textiles and they have been used in many areas of textiles.The shape memory polymers have a wider application in textile applications and polymers are more advantageous than alloys in terms of their ease of use,aesthetics,and price.
