Nanoporous Laminates



Published February 3, 2009
An organic resin matrix composition has been issued a patent. It includes a curable reaction product of: (a1) an organic resin featuring hydrogen active groups and (a2) a compound containing a thermolabile carbonate group. The thermolabile carbonate group is grafted onto the backbone of the organic resin by reaction of the compound with the hydrogen active groups: (b) a curing agent, (c) an optional solvent and (d) an optional catalyst. Heating of the organic resin matrix composition to a temperature of about 120°C to about 220°C results in thermal degradation and volatilization of the thermolabile group such that nano size voids are produced in the resulting cured organic resin matrix.
