“…Shape memory polymer (SMP) is a stimuli-responsive polymer which has an ability to fix a temporarily deformed shape and to return from the deformed shape to its original permanent shape while induced by an external stimulus such as thermal, humidity, pH, light, magnetic energy, electric field, and so on [1][2][3][4][5]. SMP possesses two phases viz.…”

Shape memory polymer (SMP) is a stimuli-responsive material with the ability to alter a programmed shape to its original shape upon triggering of an appropriate stimulus. For the past decades, SMP has dragged much interest in material field owing to its various and versatile applications. One archetypal SMP is polyurethane, which has a wideranging transition temperature for its shape recovery, retraction temperatures, inherent soft-hard segments, a high recoverable strain (up to 400%), high control of the softening, favorable and tunable physical properties, and so on. This chapter emphasizes on the raw materials required for the synthesis of shape memory polyurethane (SMPU), the principle of shape memory function, the design of protocol of SMPU, and their applications with future directions.

ÖZET: Bir tekstil yüzeyinin ıslanabilirliği esas olarak yüzeyin kimyasal yapısı ve yüzey pürüzlülüğüne bağlı olarak değişmektedir. Bilim dünyası doğada kendini temizleyebilme özelliğine sahip nilüfer yaprağı gibi nanopürüzlü yüzeylerin biyobenzetim tekniği ile benzerini üretmeyi esas alan yöntemler ve malzemeler geliştirmektedir. Bu çalışmada, tekstil yüzeylerinin ıslanabilirliği, ıslanma teorisi ve ortam şartlarına bağlı olarak ıslanabilirliği değişen yüzeyler ele alınmıştır. Bu yüzeylerin; sıcaklık, pH, ışık veya elektrik alan etkisi altında yüzey kimyası ve konformasyonunun değişimi incelenmiştir. Anahtar Kelimeler: Temas açısı, süper hidrofobluk, biyobenzetim, uyarı-cevap esaslı ıslanabilirlik Switchable Wettability On Textile Surfaces Using Nanotechnology ApplicationsABSTRACT: Wettability of a textile surface basically depends on chemical structure and roughness of surface. Science world has developed new methods and materials using biomimetics to obtain nanorough surfaces like lotus leafs which have self-cleaning feature. In this study, wettability of textile surfaces, theory of wettability and production of nano surfaces having stimuli-responsive wettability were discussed. Alteration of surface chemistry and conformation under the effects of temperature, pH, light or electrical field were examined.

Functionalization of cotton with poly-NiPAAm/chitosan microgel: Part II. Stimuli-responsive liquid management properties

et al. 2011

An innovative strategy for functional finishing of cotton involves application of stimuliresponsive surface modifying system based on temperature-and pH-responsive poly-NiPAAm/chitosan microgel. The stimuli-responsiveness implied to cotton is the consequence of swelling/collapse of the microgel particles incorporated to the fibre surface, which produces an active liquid management system. The performance of functionalized cotton fabric in terms of liquid management properties was assessed by choosing appropriate techniques (water uptake; thin-layer wicking; water retention capacity; and drying capability) and discussion of the results was based on the types of water that are expected to be present in hydrated cotton and stimuli-responsive microgel.
