摘要: Materials with aligned porous structures have broad potential in applications such as organic electronics, microfluidics, and tissue engineering. of this type can be fabricated using techniques microfabrication, soft lithography, photolithography. Directional freezing is a cheap, simple, novel route to prepare materials the form 2D surface patterns or 3D monolithic structures. A solvent—typically water but also solvents carbon dioxide—is frozen unidirectionally pore structure templated from solvent crystals that are formed. These methods produce complex composite range architectures.
