Phase change materials (PCMs) are an efficient alternative to store and release heat at a specific range of temperature. Here PCMs and heat enhancement methodologies for PCM storage are reviewed. A short overview of PCMs and their applications is presented in addition to the progress during the last 10 years. Heat enhancement techniques, that is, extended surfaces, multiple and composite PCMs, and encapsulation techniques, are presented along with a statistical overview of studies during 2016-2021. The importance of various fin and storage tank geometries (extended surfaces) is discussed in detail. Advancement in the latest heat enhancement techniques such as use of nano-enhanced PCMs is presented. Recommendations for future research are provided.

In this framework, a polymeric coating was enlarged by integrating graphene (GR) and chopped carbon fibers (CF) into the polymer mixture to be utilized for the waterproof coatings and exterior floor. The polymeric hybrid coatings were made by casting a combination of acrylic polymer, and GR, or GR-CF at room temperature. The polymer hybrids were composed of different ratios (0.25, 0.5, 1, and 2 wt%) of GR or GR-5wt% CF. The morphology, thermal stability, roughness, and the contact angle of the prepared polymer hybrids were investigated. The roughness of the fabric surface was found to be greatly reduced as the weight ratio of GR or GR-5wt% CF increased. The greatest contact angle was determined to be 83.07° for samples containing 2% GR-5wt% CF, whereas the least roughness was recorded for 2% GR and equals 1.22 µm. The addition of CF to polymers hybrid increased the roughness and contact angle. Thermal stability was improved as the weight ratio of GR, and GR-5wt% CF was increased. The maximum value of the impact strength was observed for acrylic polymer containing 1% GR-5wt% CF. The hardness of Shore A was steadily increased with increasing GR or GR-5wt% CF in the hybrid’s polymer. The presence of GR or GR-CF in the formed hybrids polymers has resulted in an improvement in the mechanical properties, wettability, thermal stability, and hydrophobicity, and hence might be employed for waterproofing coatings.

“…Within the last few decades, composite systems have become the main focus of scientists and engineers in different fields, ranging from transportation [ 1 ] and building materials [ 2 ] to thermal management [ 3 ] and energy storage [ 4 ]. This is mainly due to the flexibility of composite materials that can be tailored for specific or multiple applications.…”

Surface enhancement of components is vital for achieving superior properties in a composite system. In this study, carbon nanotubes (CNTs) were grown on carbon fiber (CF) substrates to improve the surface area and, in turn, increase the adhesion between epoxy-resin and CFs. Nickel (Ni) was used as the catalyst in CNT growth, and was coated on CF sheets via the electroplating method. Surface energetics of CNT-grown CFs and their work of adhesion with epoxy resin were measured. SEM and TEM were used to analyze the morphology of the samples. After the optimization of surface energetics by catalyst weight ratio (15 wt.% Ni), CF-reinforced plastic (CFRP) samples were prepared using the hand lay-up method. To validate the effect of chemical vapor deposition (CVD)-grown CNTs on CFRP properties, samples were also prepared where CNT powder was added to epoxy prior to reinforcement with Ni-coated CFs. CFRP specimens were tested to determine their electrical resistivity, flexural strength, and ductility index. The electrical resistivity of CNT-grown CFRP was found to be about 9 and 2.3 times lower than those of as-received CFRP and CNT-added Ni-CFRP, respectively. Flexural strength of CNT-grown Ni-CFRP was enhanced by 52.9% of that of as-received CFRP. Interestingly, the ductility index in CNT-grown Ni-CFRP was 40% lower than that of CNT-added Ni-CFRP. This was attributed to the tip-growth formation of CNTs and the breakage of Ni coating.
