| Research Abstract |
We developed a facile preparation method of porous polymer monolith by means of unidirectionally freezing of polymer solution and subsequent sublimation of the frozen-solvent in freeze-drying process. The obtained porous structure of the monolith had 1 to 100 micrometer pores aligning along the freezing direction regularly. We demonstrated the potential of our method applying to poly(L-lactide)/1,4-dioxane, poly(L-lactide)/water/1,4-dioxane, poly(L-lactide)/poly(ethylene glycol), polyurethane diacrylate UV curable resin solutions.
