[求助] 多孔的PDMS微结构是怎么形成的 已有1人参与

文章中的制作步骤是这样的:The sponges are prepared using a manufacturing technique in which a sugar scaffold is used to mould an
elastomeric polymer, in this case (poly)dimethylsiloxane (PDMS). A small glass dish was coated with a thin layer of
gold using a sputter coater to facilitate the easy removal of cured PDMS. SYLGARD® 184 Silicone Elastomer from
Dow Corning was prepared in the glass dish using 10 parts base to one part curing agent by volume. Sugar cubes
were placed in the dish, and left for 1 hour to become saturated with PDMS. The cubes were then cured in an oven
at 120 °C for 15 minutes, removed and allowed to cool. Excess PDMS was trimmed away, and the cubes put in a
beaker of distilled water to dissolve the sugar. Approximately 24 hours were allowed for this process to occur. The
water was changed several times during this period to maintain a high concentration gradient between the cube and
the water, and thus increase the rate of dissolution.
大概意思是:将方糖和PDMS混合在一起,待PDMS固化以后,再将方糖溶解,形成多孔的PDMS,但是具体操作好像很难,所以希望哪位高手指点一下

其实这个孔的形成,是先将方糖固定在PDMS中,然后将方糖溶解出来,方糖在PDMS占的体积就是孔
锅可以背,但不能不明不白
