## Abstract Three‐dimensional degradable porous polymeric structures with high porosities (93–98%) and well‐interconnected pore networks have been prepared by freeze‐drying polymer solutions in the presence of a leachable template followed by leaching of the template. Templates of the pore network
Freeze drying is a process whereby solutions are frozen in a cold bath and then the frozen solvents are removed via sublimation under vacuum, leading to formation of porous structures. Pore size, pore volume and pore morphology are dependent on variables such as freeze temperature, solution concentr
