This article discusses the creation and characterization of albumin based rigid and elastic foams. These foams were created using formaldehyde as the hardener for the protein, while camphor was used as the plasticizer. Crosslinking was carried out using a traditional or microwave oven. Samples differed in the amount of water, formaldehyde, and camphor added, and in the amount of time that they spent in the oven. The thermal conductivity was ...
This article discussed the creation of phase change composite materials using molten binary salts and expanded graphite (EG). Three different salts were used, LiNO3–KCl, LiNO3–NaNO3 and LiNO3–NaCl. The amount of salt in the composites varied between 77.8% and 81.5%. The thermal conductivity of the products was assessed to determine how it was affected by the addition of expanded graphite. The researchers determined that they had increased the thermal conductivity ...
Rubber carbon black (CB)/rubbery epoxy (RE) and CB/silicone composites with different types, loadings, and silane functionalization of carbon black were prepared. These composites were investigated for their electrical conductivities, and their mechanical properties. The thermal conductivity of each composite was also determined using a thermal constants analyzer. It was determined that the incorporation of carbon black into the composites increased the thermal conductivity in all of the samples. ...
Expanded graphite (EG) was added to lauric acid (LA)-stearic acid (SA) phase change materials to enhance their thermal conductivities. The PCMs were prepared in varying mass fractions of LA and SA, and 10 wt. % of EG was added. The phase change temperature and phase change enthalpy were determined by DSC, while the thermal conductivities, and thermal stabilities of the PCMs were determined by the transient plane source and thermogravimetric analysis, ...
Low-temperature expandable graphite (LTEG) was blended into low-density polyethylene (LDPE) to prepare composite materials with an enhanced thermal conductivity in comparison to pure LDPE. The thermal conductivity of a composite containing 60 wt. % LTEG was found to be increased by a factor of 23 in comparison to the pure polymer. The LTEG was also found to decrease the melting temperature and degree of crystallinity of the LDPE, and the composites were also ...
