Mitchell Anthamatten of Rochester University and his team have devised a method for growing foam polymers directly from gases. A mixture of gases is pumped into a low pressure reactor containing a cold surface to encourage condensation. One of the condensed liquids forms the polymer, the other temporarily occupies the spaces that become the pores in the foam material. With this process we can grow polymer coatings in which the density and pore structure varies in space, said Anthamatten. My hope is that the research leads to applications in a wide variety of fields, including medical, manufacturing, and high-tech research.
Polymers, they're a gas
