Thermal conductivity enhancement of MWNTs on the PANI/tetradecanol form-stable PCM

Enhanced thermal conductivity of n-octadecane containing carbon-based nanomaterials

“…Refs. [17][18][19][20][21][22][23][24][25][26][27]. The present results of thermal conductivity enhancement can be justified by this comparison although there is an uncertainty due to uncertainties in the materials specifications, preparation method and thermal conductivity measurement techniques.…”

“…Also, a reduction of 23 % in solidification time of sample with 1 wt% CNFs was observed. Zeng et al [18] prepared a form stable PCM from 1-tetradecanol (C 14 H 30 O), polyaniline and MWCNTs with mass fractions of 0.5, 1, 2.5 and 5 wt%. Measurement by transient plane source (TPS) technique showed that thermal conductivity changes from 0.33 to 0.43 W/m K (almost 30 % enhancement) at mass fraction of 5 %.…”

Diaminium salt as reactive amphiphile for the synthesis of poly(m-phenylenediamine) and paraffin microencapsulation

“…In this application, microencapsulation allows the integration of PCM and construction materials with excellent results [70]. Few reports concerning polyaniline-based PCM were found in literature, all of them achieved by the emulsion technique using in most cases a surfactant as stabilizer which was an important variable [71][72][73][74][75]. These systems presented both high thermal stability (TGA) and high phase change enthalpy (DSC) which makes these composites very attractive.…”

Fabrication and characterization of capric–lauric–palmitic acid/electrospun SiO2 nanofibers composite as form-stable phase change material for thermal energy storage/retrieval

“…In order to improve its thermal conductivity, various methods have been explored. The most acknowledged method is to add particles with high thermal conductivity coefficients and incorporate porous structure materials such as expanded graphite (Dheep and Sreekumar, 2014;Wang et al, 2014;Meng et al, 2012;Zhang et al, 2013;Yang et al, 2014), expanded perlite Sari and Karaipekli, 2008), activated-attapulgiate (Song et al, 2014), carbon nanotubes (Dheep and Sreekumar, 2014;Meng et al, 2013;Wang et al, 2010Wang et al, , 2008Zeng et al, 2008), diatomite (Li et al, 2011a,b), and vermiculite Sari, 2009, 2010) into the PCMs. As for preventing the leakage of PCMs during the solid-liquid phase change, the form-stable composite PCMs containing silicon dioxide (Fang et al, 2010(Fang et al, , 2011, expanded graphite Meng et al, 2012;Zhang et al, 2013;Yang et al, 2014), expanded perlite Sari and Karaipekli, 2008), polymers including polyethylene terephthalate, polyamide 6, polyurethane, polyacrylonitrile and derived carbon (Cai et al, 2011(Cai et al, , 2012a(Cai et al, ,b, 2013aChen et al, 2008;Ke et al, 2013;Giro-Paloma et al, 2013;Zhang et al, 2012), activated-attapulgiate (Song et al, 2014), diatomite (Li et al, 2011a,b), and vermiculite Sari, 2009, 2010) as support materials have been investigated.…”
