【求助】支架材料的制备方法
|
|||
|
看到一篇文献，制备支架材料，叙述如下： Scaffold preparation by solid–liquid phase separation: a known amount of polylactide was dissolved in dioxane to form solutions with desired concentrations. Four different concentrations of PLLA solution (0.5, 1.0, 3.0 and 5.0% w/v) were frozen and maintained over 2 hr to induce solid–liquid phase separation completely. The clear 5% PLLA solutions were poured into aluminum foil molds (4x4 cm2) which were fast-frozen in liquid nitrogen, ice-water bath or freezer, respectively, and then were maintained at those temperatures for over 2 hr to induce solid–liquid phase separation completely. Solvent was removed by freeze-drying for 3 days and the dried scaffolds were then kept in a desiccator until characterization or usage. 此方法是固液相分离法。把PLA溶在dioxane中，通过冷冻就可以固液相分离吗，什么原理啊？ 冷冻后为什么会出现固液分离(solid-liquid phase separation)啊?
