Evaluation of solubility enhancement of carbon dioxide in polystyrene via introduction of water

Morphological evaluation of ultralow density microcellular foamed composites developed through CO2-induced solid-state batch foaming technique utilizing water as co-blowing agent

“…Among the several co-blowing agents such as alcohol, ketone, water and nitrogen, water has more advantages as easy availability, low cost, non-toxic and very high heat capacity. 39 After ethanol, water has good interaction and compatibility with CO 2 due to its interaction energy of about 11.56 KJ/mol. 31 The interaction energy between the additives and polymer chain is more than that of between the pure CO 2 and polymer chain.…”

“…Both expansion ratio and cell size obtained by utilization of co-blowing agent more than by the individual CO 2 which gives better thermal insulation applications. 39,42…”

“…Both expansion ratio and cell size obtained by utilization of co-blowing agent more than by the individual CO 2 which gives better thermal insulation applications. 39,42 In this work, a solid-state batch foaming technique with water as a co-blowing agent was used to manufacture microcellular ABS foam at the various levels of the different processing parameters to evaluate its morphological attributes. This work to evaluate the effect of water content along with the foaming parameters like saturation temperature, saturation pressure and saturation time on cell morphology.…”
