Three-dimensional polypyrrole microcapsules were prepared via chemical deposition of the polymer onto tetradecanol particles supported on solid substrates. The growing polymer deposited onto the particle surface yielded hemispherical containers that encapsulated the tetradecanol contents. Mixing the tetradecanol with other chemical species, like fluorescent dyes, allowed the entrapment of these species within the containers. It was shown that by controlling the temperature, one could reversibly melt and solidify the tetradecanol content of the capsules. The tuning of the fluorescence intensity emitted from the capsules could thus be controlled. The polypyrrole structures were characterized using several complementary experimental methods. These included microscopic (scanning electron microscopy, atomic force microscopy, and optical microscopy) and spectroscopic techniques (steady-state fluorescence, ultraviolet-visual light absorption, and infrared spectroscopy) as well as conductivity and contact angle measurements.

“…Sun et al presented a bifunctional PCM composite on polyaniline/tetradecanol that possessed energy storing capability and, at the same time, can conduct electricity. 82 In other work for augmenting thermal conductivity, Koratkar and co-workers showed that the addition of 4 wt % graphene to octadecanol increased the thermal conductivity by ∼140%. 83 Mu and Li studied tetradecanol as a PCM, wherein they developed a form-stable PCM by using graphene aerogels, where the resulting PCM displayed good thermal conductivity and high LHS (∼190 J/ g).…”

Phase-change materials (PCMs) are utilized for thermal energy storage (TES) to bridge the gap between supply and demand of energy. Organic PCMs, similar to paraffins, fatty acids, and polyethylene glycol, are extensively explored, thanks to their high TES capacity (∼5–10 times more than the sensible heat storage of water/rock), wide temperature range (spanning from −5 °C to 190 °C), good thermal stability over heating–cooling cycles (∼100 cycles), etc. However, “leakage” of PCMs upon transformation from solid to liquid has limited their usage as TES materials; thus, PCMs are confined to a biopolymeric framework for circumventing seepages. However, extensive analysis has concluded that there is a deficiency in availability of consolidated data on biopolymeric-based framework for PCMs. Thus, this review covers various literatures on the application of assorted biopolymers as framework for PCM. Simultaneously, we have also discussed on importance of biopolymers for constructing a framework for PCMs. Finally, the review concludes with future prospects, along with possibilities and disputes on the course of their practical application.

“…30,32 PANI is a widely investigated conductive polymer and is preferred to be synthesized in an aqueous solution. It has been applied as a supporting material to prepare fatty acids 37,38 and fatty alcohols 39 form-stable PCMs. Its high thermal stability implies that it is a good supporting material for sugar alcohols.…”

Summary Sugar alcohols are promising solid‐liquid phase change materials (PCMs). However, problems such as possible leakage of liquid PCMs, high and unstable supercooling, and low thermal conductivity need to be solved. In this work, a novel form‐stable PCM in which m‐erythritol (ME), polyaniline (PANI), and silver nanowires (Ag NWs) were applied as solid‐liquid PCM, supporting material, and thermal conductive filler, respectively, was successfully prepared in anhydrous ethanol by surface polymerization of aniline. Form‐stable PCM with good form stability could be obtained when the ratio of ME/(aniline + ME) was no more than 78.7 wt%. The melting enthalpy (ΔHm) of the ME/PANI form‐stable PCMs could attain 234.8 J/g while that of the ME/PANI/Ag NWs form‐stable PCMs was about 220 J/g. In addition, the thermal conductivity of the form‐stable PCM was increased by 61.6% when 7.5 wt% Ag NW was added. Moreover, the supercooling of ME was effectively suppressed from 100°C for pure ME to 60°C, corresponding to an improvement of 40%, for the form‐stable PCM containing 7.5 wt% Ag NWs. The supercooling suppression could be ascribed to that PANI provided great amounts of nucleating centers and improved the nucleation kinetics, and Ag NWs improved the thermal diffusivity and thus increased the crystallization rate.
