Preparation of capric acid/halloysite nanotube composite as form-stable phase change material for thermal energy storage

Kaolinite stabilized paraffin composite phase change materials for thermal energy storage

“…In addition, the latent heats and thermal conductivities of the prepared composite PCM are compared with those of clay mineralbased composite PCM in the literature in Table 1 Sarı and Karaipekli, 2008;Sarı et al, 2009;Karaman et al, 2011;Li et al, 2011aLi et al, ,b, 2013aMei et al, 2011b;Sarier et al, 2011;Sarı and Biçer, 2012;Sun et al, 2013;Zhao et al, 2014), the kaolinite/paraffin composites showed obvious advantages over the reported materials. In particular, the as-prepared LKaol/paraffin composite showed excellent potential as a solar thermal energy storage material for a low temperature solar-thermal system for solar passive heating purposes.…”

Properties and applications of halloysite nanotubes: recent research advances and future prospects

“…Based on its molar mass also called molar weight (MW), guests loaded on Hal could be listed in either of the following categories: i) low MW substances with MW b 300 g/mol, e.g., propranolol hydrochloride (Levis and Deasy, 2003), 5-aminosalicylic (Viseras et al, 2008(Viseras et al, , 2009Aguzzi et al, 2013), benzotriazole (Shchukin and Mohwald, 2007;Abdullayev et al, 2009;Abdullayev and Lvov, 2010), 8-hydroxyquinoline (Fix et al, 2009), glycerol (Suh et al, 2011), stearic acid (Mei et al, 2011a), capric acid (Mei et al, 2011b), resveratrol (Vergaro et al, 2012), ibuprofen (Tan et al, , 2014b, and 5-fluorouracil (Rao et al, 2014); ii) medium MW substances with 300 g/mol b MW b 1000 g/mol, e.g., dexamethasone, furosemide, nifedipine (Veerabadran et al, 2007(Veerabadran et al, , 2009, fentanyl (Forsgren et al, 2010), doxorubicin (Mitchell et al, 2012), and orange II (Yuan et al, 2012b); iii) high MW substances with MW N 1000 g/mol, e.g., metalloporphyrins (Machado et al, 2008), α-amylase , urease (Shchukin et al, 2005;Zhai et al, 2010), antisense oligonucleotides (Shi et al, 2011), and insulin .…”

Preparation and characterization of capric-myristic-stearic acid eutectic mixture/modified expanded vermiculite composite as a form-stable phase change material

“…In practice, fatty acids are impregnated into porous building materials to prepare form-stable composites. Considering the strong capillary force generated on a pore with small diameter [9], a variety of natural porous materials with smaller pores such as expanded perlite [10,11], attapulgite [12] and halloysite [13], are frequently used to avoid the leakage of fatty acids during melting process. Additionally, the low thermal conductivity of fatty acids poses a challenge for their applications.…”
