Patent ID: 8268411

Claim:
A method of forming a porous composite material comprising: providing a precursor combination of a first precursor and a second precursor into a reactor chamber, wherein at least one of said first or second precursor is a porogen selected from the group consisting of a liner compound containing at least one C═C double bond and an alcohol; depositing a film from said precursor combination; and removing said porogen from said film to provide a porous composite material comprising a first solid phase having a first characteristic dimension and a second phase comprised of pores having a second characteristic dimension, wherein said pores have a pore size distribution having a maximum that is less than about 1 nm, a full width at half maximum in the pore size distribution ranging from 1 to 3 nm, and with a fraction less than 0.1 of pores having a pore size of greater than about 1 nm, and wherein said removing said porogen comprises UV treatment in a vacuum, a reducing environment containing H 2 , or a pure inert gas.
