abstract = "Water can act as a co-blowing agent for carbon dioxide (CO2) based polystyrene foaming. With the introduction of water into the foaming process, it is possible to produce foams with ultra-lower density. Herein, we report a modified method to prepare water expandable polystyrene (PS)-activated carbon (AC) composites using suspension polymerization of inverse emulsion. PS is hydrophobic and does not absorb any water. Thus, a good water absorbent carrier such as activated carbon can be used to carry water in the foaming process. Activated carbon pre-saturated with water is introduced into the styrene monomer resulting in the formation of water-in-oil inverse emulsion. Via suspension polymerization, spherical water/activated carbon PS beads could be subsequently obtained. By the extrusion foaming process, a PS/AC composite foam with ultra-low density (∼0.03g/cc) is successfully produced.",
