Abstract
A hybrid porous structure may include a base template and an ionic polymer coating layer within the base template. The structural framework of the base template itself is non-porous. The base template fills the gaps among a plurality of imaginary spherical bodies stacked in three-dimensions as an imaginary stack. The ionic polymer coating layer is laminated on an inner surface of the base template inside the imaginary spherical bodies. The imaginary spherical bodies may have a pore in the center which is not occupied by the ionic polymer coating layer. The hybrid porous structure may include a plurality of necks, which are openings formed in a contact part where adjacent imaginary spherical bodies contact each other. The necks may be interconnected to the pores located in the center part of the imaginary spherical bodies.
