A bioresorbable porous film, including a blend mixture of polylactic acid and at least two kinds of polyethylene glycol, wherein the at least two kinds of polyethylene glycol include a first polyethylene glycol, which is in a solid form under ambient temperature and atmospheric pressure, and a second polyethylene glycol, which is in a liquid form under ambient temperature and atmospheric pressure is provided. The film has a porosity of 10%-90%.

Bioresorbable porous film

The disclosure provides a solid form and a method for preparing the same. The solid form consists essentially of a biodegradable copolymer and an amide-containing compound. The biodegradable copolymer is semi-crystalline due to the dipole-dipole interaction between the biodegradable copolymer and the urea. The method for preparing the above solid form includes: dissolving a biodegradable copolymer and an amide-containing compound in water at a first temperature, obtaining a solution; cooling the solution at a second temperature to form a solid mixture; and the solid mixture is subjected to a freeze-drying process at a third temperature.
