In the presented work, nano-sized carbon particles were coated onto the surface of semicrystalline polymer pellets and molded into an intermediate preform, with a honeycomb-like structure, at elevated temperatures and pressures. The preforms were fur

Extrusion foaming using supercritical carbon dioxide (CO2) as the blowing agent is an economically and environmentally benign process. However, it is difficult to control the foam morphology and maintain its high thermal insulation comparing to the c

Carbon particles such as platelet-like graphite (GR), spherically shaped activated carbon (AC), and tubular carbon nanofiber (CNF) were used as additives in extruded polystyrene (PS) foams with carbon dioxide (CO2) and water as co-blowing agents. It

Exfoliated layered-silicate in the polystyrene (PS) block copolymer with different molecular weights was employed as a model material to investigate the PS nanocomposite microcellular foams expanded by supercritical carbon dioxide. Using a well-contr

In this study, water acts as a co-blowing agent to support carbon dioxide (CO 2 ) in the extrusion foaming process of polystyrene (PS) to produce foams with very low density for thermal insulation applications. Herein, we report a simple suspension p

The typical process used to synthesize water expandable polystyrene (WEPS) was modified and applied to prepare water expandable polystyrene (PS)–clay nanocomposites (WEPSCN). The natural clay can be uniformly dispersed in water due to its hydrophil

Photopolymerization is a widely used technique to synthesize polymers and hydrogels. The commonly used ultraviolet (UV)-curable mono-, di- or multifunctional vinylated monomers are often volatile, causing difficulty in kinetics analysis such as photo

In this study, the use of carbon nanofibers (CNFs) as nucleating agents to produce polystyrene nanocomposite foams was demonstrated. With the addition of CNFs, microcellular foams with uniform cell size distributions were obtained. Compared to nanocl
