This article focused on determining the extinction coefficient of polyolefin foams. A combination of experimental and theoretical methods were used to accomplish this goal. Samples differed from each other in terms of thickness, chemical composition, colour, density, and structural characteristics. Fourier transform infrared spectroscopy was ...
Low-density microcellular non-isocyanate polyurethane (NIPU) foams were prepared using biological compounds and carbon dioxide. The morphology of these foams was investigated by scanning electron microscopy (SEM), and the thermal conductivity was determined using the transient plane source (TPS) method. It was concluded that a study ...
Graphite nano-platelets (GnPs) were dispersed in polyethylene glycol (PEG)/polymethyl methacrylate (PMMA) to form a PEG/PMMA/GnPs composite organic form-stable phase change material. The effects of the incorporation of the GnPs on the morphological, structural, thermal, and electrical properties of the composite were then ...
Ambient pressure dried hydrophobic silica aerogel monoliths were prepared via simultaneous solvent exchange and surface modification in order to minimize volume shrinkage and density. At room temperature, the obtained silica aerogels had a low density of 0.096 g/cm3, a high surface area and hydrophobicity, and ...
Composite phase change materials were prepared using stearic acid, coffee grounds, and graphite. The coffee grounds were used as a supporting material for the stearic acid, and the graphite was added in an effort to enhance the thermal conductivity of the composite. The composites were ...
