Abstract

Foaming of polymers with CO₂ has attracted increasing attention in polymer processing studies. Some of the fundamental properties of polymer/CO₂ systems is discussed in this short review, including solubility and diffusivity of CO₂ in the polymer, polymer crystallization, interfacial tension between the polymer and the gas, and rheology of the CO₂/polymers melt. These properties understandably affect the foaming process, and the structures of the foam products. Meanwhile, these properties can be changed via manipulation of CO₂ in polymer. The proposed idea is to manipulate the foaming process and the foam structure by CO₂-induced changes in these properties. Two cases from the authors’ laboratory are presented for elucidating how to use the changes to manipulate the foaming process.
