Nonwoven fibrous materials based on the biopolymer polyhydroxybutyrate were prepared by electrospinning. The nonwoven materials could be divided into three arbitrary groups, uniform, medium-density, and random, according to macrostructural features (nature of the distribution of fibers in the material bulk). The supramolecular structure of the fibers practically did not change regardless of the type of distribution. The amount of absorbed ozone was shown to depend on the morphology of the nonwoven fibrous material. The volume of absorbed ozone increased with increasing surface density of the nonwoven material, which indicated that oxidative degradation was accelerated.

非织造超细纤维状聚羟基丁酸酯材料的形态对与臭氧相互作用的影响

通过电纺丝制备基于生物聚合物聚羟基丁酸酯的非织造纤维材料。根据宏观结构特征（材料块中纤维分布的性质），非织造材料可分为均匀，中等密度和无规三类。不管分布的类型如何，纤维的超分子结构实际上都没有改变。已显示吸收的臭氧量取决于非织造纤维材料的形态。随着非织造材料表面密度的增加，吸收的臭氧量增加，这表明氧化降解被加速。
