1. A composite for absorbing condensable gas or vapor from an atmosphere or a gas or a vapor stream, comprising:
a hydrophilic matrix;
a hydrophilic solid material in the hydrophilic matrix to form one or more contact spots; and
a porogenic material embedded in the matrix, having a size larger than the hydrophilic solid material,
wherein selective removal of the porogenic material from the hydrophilic matrix forms a hierarchically porous matrix with pore spaces, and
wherein the condensable gas or vapor is captured, and condensed gas or vapor is stored in the hydrophilic matrix and/or pore spaces in the hierarchically porous matrix.
