Since the discovery of the shape-memory polymers (SMPs) in the 1980s, international research interest into the shape-memory effect in polymers has been rapidly growing [1], [2], [3], [4], [5], [6], [7]. The SMPs are stimuli-responsive smart materials with the ability to undergo ...
SHAPE MEMORY POLYMERSThe present disclosure relates to Shape Memory Polymers (SMP's) comprising function groups that allow the polymers to be elastically deformed, utilized in the elastically deformed state, and subsequently returned to the original polymorphic shape.ANTHAMATTEN, MITCHELL, L...

Shape memory polymersShape memory polymersShape memory polymers (SMP) are increasingly popular in the fabric engineering as they respond dynamically to changes in heat and moisture levels, ensuring greater comfort for the wearer. They are thus often used to produce high-end functional garments. It ...
Shape-memory effect (SME) is the ability of a material to change its dimension in a predefined way in response to an external stimulus. Polymers that exhibit SME are an important class of materials in medicine, especially for minimally invasive deployment of devices. However, the rate of transl...
Shape-memory polymers (SMPs) offer a number of potential technical advantages that surpass other shape-memory materials such as shape-memory metallic alloys and shape-memory ceramics. The advantages include high recoverable strain (up to 400%), low density, ease of processing and the ability to ...
Shape-memory research was initially founded on the thermally induced dual-shape effect. This concept has been extended to other stimuli by either indirect thermal actuation or direct actuation by addressing stimuli-sensitive groups on the molecular level. Finally, polymers are introduced that can be ...
As a new class of smart materials, shape memory polymers and their composites (SMPs and SMPCs) can respond to specific external stimulus and remember the original shape. There are many types of stimulus methods to actuate the deformation of SMPs and SMPCs, of which the thermal- and electro-...
