Abstract

The rapid progress and innovation of modern materials in engineering sciences are enabling us to overcome many limitations due to traditional materials used in various engineering and biomedical fields. Additionally, it is helping us to develop new products. Intelligent materials such as shape memory polymers (SMPs) have played a vital role in this field. They have unique ability to recover their original shape upon external stimuli such that temperature, light, electricity, water, pH, magnetism and specific ions. The SMPs are currently used in wider range of engineering disciplines due to their exceptional structural properties like good manufacturability, high shape deformability and recoverability. Additionally SMPs have shown a good prospective development in the biomedical applications due to their special characteristics such as biocompatibility, biodegradability, low rejection by host, low density and fairly good glass transition temperature (Tg). Recently developed SMPs are used in self-tightening sutures, controlled drug delivery systems, self-retractable and removable stents, fasteners and scaffolds for tissue engineering, endovascular clot removal, orthodontic appliances, etc. In this article recent advancement of the SMP materials and their applications are discussed.
