“…On the other hand, a few new shape memory phenomena have been discovered [31][32][33][34][35][36][37][38][39][40][41][42][43][44][45][46][47], which not only enhance the flexibility of the current shape memory technology, but also add in new dimensions for extended versatility and adoptability. Consequently, a number of novel concepts have been proposed for a range of engineering applications [45,[48][49][50][51][52][53][54], in particular in the field of biomedical engineering as of the last couple of years [24,43,[55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70].…”

Abstract:This review paper summarizes the recent research progress in the underlying mechanisms behind the shape memory effect (SME) and some newly discovered shape memory phenomena in polymeric materials. It is revealed that most polymeric materials, if not all, intrinsically have the thermo/chemo-responsive SME. It is demonstrated that a good understanding of the fundamentals behind various types of shape memory phenomena in polymeric materials is not only useful in design/synthesis of new polymeric shape memory materials (SMMs) with tailored performance, but also helpful in optimization of the existing ones, and thus remarkably widens the application field of polymeric SMMs.

“…The applications of stimuli-active polymers in textiles can be broadly classified into finishing (coating and laminating) and built-in (blending and spinning) methods. 1 Moreover, polymer nano-composites offer the possibility of developing a new class of finishing materials for these classes of textiles. 2 Textiles can possess skincare properties; they are called cosmetotextiles.…”

Cosmetotextiles are novel textiles which contain carriers with active and cosmetic substances, these carriers, generally by polymeric nature, release their active compounds when in contact with the human body. The aim of this mini review work is to report the new developments in cosmetic textiles, focusing in the obtaining of microcapsules containing skin care substances, physically or chemically bound to the fiber surface. The selection of the encapsulation technique and shell material depends on the final application of the product, considering physical and chemical stability, concentration, required particle size, release mechanism and manufacturing costs. This review discusses the most commonly used microencapsulation processes as: interfacial polymerization, In Situ polymerization, coacervation and phase separation, spray drying and electro spraying. Microcapsules can be applied to the textiles by different methods: padding, coating, spraying or immersion methods. All these methods are also briefly explained here. To the end of this article, some commercial products are listed. Keywords

“…[38][39][40][41][42][43] Among others, thermo-responsive polymers are particularly attractive because they show a drastic change in physico-chemical characteristics as a result of phase transition upon heating. 44,45 Poly(N-isopropylacrylamide) (PNIPAM) is one of the most well-known temperature sensitive polymers applied for the synthesis of macrogels and microgels (MG).…”

Polyelectrolyte multilayers serve as effective reservoirs for bioactive molecules which are stored and released from the multilayers for cellular applications. However, control over the release without significantly affecting the multilayers and biomolecules is still a challenge. On the other hand, externally stimulated release would make the multilayers promising for the development of stimuli-sensitive planar carriers with release performance switched on demand. In this study soft composite films are designed by coating hyaluronic acid/poly-L-lysine (HA/PLL) multilayers with temperature responsive poly-(N-isopropylacrylamide) (PNIPAM) microgels. Microgels are flattened and immersed into the multilayers to maximize the number of contacts with the surrounding polyelectrolytes (HA and PLL). The microgel coating serves as an efficient switchable barrier for the PLL transport into the multilayers. PLL diffusion into the film is significantly hindered at room temperature but is dramatically enhanced at 40 1C above the volume phase transition temperature (VPTT) of PNIPAM at 32 1C associated with microgel shrinkage. Scanning force microscopy micrographs show that the mechanism of volume phase transition on soft surfaces cannot be directly deduced from the processes taking place at solid substrates.
