Porous scaffolds, of biodegradable synthetic

Preparation of Porous Scaffolds of Biodegradable Synthetic Polymers.87... 

The embossing ice particulates can be used to control the surface pore structures and to create micropatterned structures in porous scaffolds of naturally derived biodegradable polymers. When free ice particulates that are not embossed on a substrate are used, the inner body pore structures of biodegradable polymers can be controlled. In this case, preprepared ice particulates are used as a porogen material. The ice particulates are mixed with precooled polymer solution. The mixture is subsequently frozen slowly and freeze-dried. This method has been used to prepare porous scaffolds of biodegradable synthetic polymers and biodegradable naturally derived polymers [16-18,22].
