摘要

Polyaniline-clay (PANI-MMT) nanocomposites were synthesized through in-situ polymerization of polyaniline with various dopants.Those nanocomposites were used to blend with polystyrene (PS) to form an expandable composite resin, which will significantly impact the foaming process using a CO2 blowing agent.The material composition and foam morphologies were characterized through various analytical techniques, such as, X-Ray diffraction (XRD), SEM, dielectric measurement, UV/vis, and FTIR.Based on our experimental results, we are proposing that the "de-doped base form" of Pani-MMT nanocomposites and both "inorganic and organic salt-form" Pani-MMT nanocomposites will act as a "molecular CO2 reservoir" to control the CO2 releasing during the foaming.The selection and optimization on those compounds will be enormously important for developing a new, inexpensive, and environmental friendly blowing agent for the foam industry to achieve the final goal of replacing the existing CFCs/HCFCs/HFCs blowing agents.
