Abstract

In this study, smart nanocomposite films possessing both thermal and water/moisture responsiveness were produced with addition of cellulose nanocrystallite (nanowhisker) (5, 10 and 20 wt%) as nanofiller material. The water/moisture responsiveness was obtained by this modification which is easier than chemical synthesis of the polymer and dual sensitivity of the produced nanocomposite films were examined in detail by thermo-mechanical-aqueous shape memory test procedures. Additionally, particle distribution and matrix-nanofiller interactions of the produced films were investigated by SEM, FT-IR and XRD analyzes. According to the results, it was found that mechanical properties of the films improved as expected. Moreover, besides thermal sensitivity, water/moisture sensitivity increased proportional to the cellulose nanocrystallite (nanowhisker) concentration. 

Özet

Bu çalışmada, yaygın olarak kullanılan şekil hafızalı polimerlerden poliüretana eklenen selüloz nanokristalit (nanowhisker) dolgu maddesi (%5, 10, 20) ile sıcaklığın yanı sıra su/neme duyarlı akıllı nanokompozit filmler üretilmiştir. Kimyasal senteze göre daha ucuz ve kolay olan bu modifikasyonla elde edilen ikinci (su/nem) duyarlılık, termal-mekanik-sulu şekil hafıza test prosedürleri ile ayrıntılı olarak incelenmiştir. Ayrıca, üretilen nanokompozit filmlerde partikül dağılımı ve matris-nanodolgu etkileşimleri SEM, FT-IR ve XRD analizleriyle belirlenmiştir. Elde edilen sonuçlara göre, beklendiği gibi nanodolgu malzemesinin yapının mekanik özelliklerinde iyileşmenin yanı sıra sıcaklık duyarlılığa ek olarak selüloz nanokristalit (nanowhisker) konsantrasyonuyla doğru orantılı artan su/nem duyarlılığını da oluşturduğu tespit edilmiştir.
