Microstructural Modelling of Diffusive Transport in Porous Polymers

建议对不可腐蚀和生物可腐蚀聚合物的孔结构和形态进行实验研究。这两种聚合物都表现出复杂的结构体系，生物可腐蚀组分将显示出动态变化的孔结构。虽然可能不可能在拨款的限制下对这些系统进行完全计算机化的图像分析，但扫描电子显微镜(SEM)和光学显微镜将提供对这些系统的孔形态的定量洞察。在侵蚀过程中的不同时间拍摄的聚合物的显微照片将允许跟踪变化的结构，以便为系统模型的建立提供了基础。

It is proposed to study experimentally both nonerodible and bioerodible polymer pore structure and morphology. Both polymers exhibit structurally complex systems, and the bioerodible components will show a dynamically changing pore structure. Although it may not be possible to perform a fully computerized image analysis of these systems within the constraints of the grant, scanning electron microscopy (SEM) and light microscopy will provide quantitative insight into the pore morphology of these systems. Photomicrographs of the polymer taken at various times during the erosion process will allow the changing structure to be followed in order to provide the basis for the system model.
