The effect of PEG molecular weight on the membrane structure and properties of PLLA/PEG blends
碩士 === 國立臺灣大學 === 材料科學與工程學研究所 === 92 === The effect of PEG molecular weight on the structure of porous membranes of PLLA/Peg blend was studied. The porous membranes were prepared by wet casting method. In this work, the solvent was 1,4-dioxane and the non-solvent was n-Heptane. Via the phase diagram...

The porous membranes were prepared by wet casting method. In this work, the solvent was 1,4-dioxane and the non-solvent was n-Heptane. Via the phase diagram, it was realized how liquid-liquid de-mixing and solid-liquid de-mixing varied with the molecular weight of PEG. The structure of porous membranes prepared with different condition can be observed clearly by SEM. Also, the crystallinity of membranes with dipping time can be studied utilizing DSC. Through the above work, it was found how PEG molecular weight affected the structures of PLLA/PEG porous membranes. 廖文彬 2004 學位論文 ; thesis 121 zh-TW |
