Şekil
hafızalı polimerler, çevresel uyaranların etkisi ile özelliklerinde belirgin
değişiklikler gösterebilen akıllı malzemelerdir. Son yıllarda, akıllı
tekstiller grubunda yer alan şekil hafızalı polimerlerle ilgili çalışmalarda, çoğunlukla
sıcaklık ve su/nem duyarlılığa yoğunlaşılmıştır. Literatürdeki çalışmalarda şekil
hafızalı polimerlerin tekstil uygulamaları lif çekimi, iplik ve kumaş oluşumu,
film, kaplama, laminasyon ve bitim işlemlerinden oluşmaktadır. Bu çalışma
kapsamında, şekil hafızalı polimerlerin yapı ve şekil hafıza mekanizmalarının yanı
sıra, bu özelliğin polimerden tekstil malzemesine dönüşümü ile ilgili uygulamalar
da ayrıntılı olarak incelenmiştir. Ayrıca şekil hafızalı polimerlerin
belirtilen tekstil üretim proseslerindeki kısıtlamaları ile yakın gelecekteki
potansiyel uygulamaları da tartışılmıştır. 

Anahtar Kelimeler

Şekil hafızalı polimerler, akıllı tekstiller, şekil hafızalı lif/iplik, şekil hafızalı kumaş, şekil hafızalı laminasyon/kaplama, şekil hafızalı bitim işlemi

Shape Memory Polymers and Textile Applications

Öz

Shape
memory polymers are smart materials that could exhibit significant changes in
their properties with effect of environmental stimuli. In recent years, studies
covering shape memory polymers, a branch of smart textiles, have focused on temperature
and water/humidity sensitivity. In literature, textile applications of shape
memory polymers consist of fibre spinning, yarn and fabric formation, film,
coating, lamination and finishing applications. In this study, structural and
shape memory mechanisms of shape memory polymers were explained and applications
related to transformation of shape memory property from polymer to textile
material were examined in detail. Furthermore, limitations of shape memory
polymers in the mentioned textile production processes and their potential
applications in near future were also discussed.
