AB  - Fazdeğiştiren maddeler (FDMler), ısıl enerjinin gizli ısı olarak depolanabilmesineolanak tanıyan ve yüksek gizli ısı depolama kapasiteleriyle oldukça geniş biryelpazedeki ısıl enerji depolama uygulamalarında kullanılabilen malzemelerdir. FDMlerinorganik sınıfında yer alan parafinler, yüksek gizli ısı depolama kapasiteleri,ısıl ve kimyasal kararlılıklarıyla ön plana çıkmaktadır. Bununla beraber bumalzemelerin ısıl enerji depolamada doğrudan kullanımı, sıvı faz halinde sızdırmapotansiyeli nedeniyle uygun değildir. Dolayısıyla bu malzemelere uygulanacakmakro/mikro ölçekli kapsülasyon işlemi uygun çözüm yollarından biridir. Ayrıca bumalzemelerin yapısal, kimyasal ve ısıl kararlılıklarının arttırılması amacıylaçeşitli inorganik gözenekli dolguların kapsülasyon işlemi esnasında destekmalzeme olarak ilavesi de mümkün olmaktadır. Bu çalışmada, FDMlerden biri olann-oktadekan (OD) ağırlıkça %15-35 oktadesilamin ve %0,5-5aminopropiltrietoksisilan ile yüzeyi modifiye edilmiş montmorillonit kilivarlığında faz inversiyon emülsifikasyonu yöntemiyle mikro boyuttakapsüllenmiştir. Hazırlanan mikrokapsüllerin faz değişim sıcaklık aralığı, ısılenerji depolama kapasiteleri ve ısıl kararlılıklarıyla düşük sıcaklıktaki(20-35°C) gizli ısı depolama uygulamalarında kullanılabilme potansiyelleri araştırılmıştır.

N2  - Phase change materials (FDMs) are materials that allow thermal energy to be stored as a latent heat and can be used in a widerange of thermal energy storage applications owing to its high latent heat storage capacities. The paraffins in the organic classof FDMs are come into prominence by their high latent heat storage capacities, thermal and chemical stability. However, thedirect use of these materials in the storage of thermal energy is not suitable because of its potential risk to leakage in liquidphase. Therefore, the macro / micro scale encapsulation process to be applied to these materials is one of the suitable solutionways. It is also possible that adding various inorganic porous fillers as a support material during the encapsulation process toincrease the structural, chemical and thermal stability of these materials. In this study, n-octadecane (OD), one of the FDMs,was encapsulated in micro-size by phase inversion emulsification in the presence of surface modified montmorillonite claycontained 15-35 wt% octadecylamine and 0.5-5 wt% aminopropyltriethoxysilane. The usage potential of microcapsules inlatent heat storage applications at low temperature (20-35 ° C) with owing to phase change temperature range, thermal energystorage capacities and thermal stabilities were investigated.
