A method providing direct access to porous three-dimensionally (3D) continuous polymer network structures and shapes by combining BCP-resol co-assembly with CO.sub.2 laser-induced transient heating. The CO.sub.2 laser source transiently heats the BCP-directed resol hybrid films to high temperatures at the beam position, inducing locally controlled resol thermopolymerization and BCP decomposition in ambient conditions. This enables shaping of BCP-directed porous resin structures with tunable 3D interconnected pores in a single process. Pore size can be varied from 10 nm to about 600 nm.

The present invention provides: a gas separation method which is capable of desirably separating a slight amount of a component from a mixed gas under mild conditions such that the pressure difference between both sides of a gas separation membrane is 1 atmosphere or less; and a gas separation membrane which is suitable for use in this gas separation method. According to the present invention, in a gas separation method wherein a specific gas (A) in a mixed gas, which contains the specific gas (A) at a concentration of 1,000 ppm by mass or less, is selectively permeated with use of a gas separation membrane, an extremely thin gas separation membrane that has a film thickness of 1 μm or less is used, so that the gas (A) is desirably separated under mild conditions such that the pressure difference between both sides of the gas separation membrane is 1 atmosphere or less.
