3.4. Porosity of PLGA/PHBV scaffold
Some parameters related to the scaffolds such as porosity,average volume, pore volume per gram and density were exhibited in Fig. 4. The porosities of three kinds of scaffold were slightly below the pre-set value. The porosity of pure PLGA scaffolds reached to 81.830¡À1.723%, which was close to that of PLGA/30% PHBV scaffolds (81.273¡À2.192%). When the PHBV microspheres content came to 50%, the porosity of the scaffolds still showed no statistical significant when compared with that of pure PLGA scaffolds. The result demonstrated that the PHBV microspheres had little influence on the porosity of PLGA scaffold. With the increase  of PHBV microspheres, the density of scaffolds increased accordingly (from 0.17290¡À0.00461 of pure PLGA to 0.25160¡À0.03828 of PLGA/50% PHBV). At the same time, the pore volume per gram decreased with the increase of PHBV microspheres. The above two graphs coincided well with each other. Because of the augment of density, the volume of every gram of the scaffolds should have reduced.
