New oil-in-alcohol highly concentrated emulsions were formulated and were used as a templates to obtain macroporous poly(furfuryl alcohol) monoliths by a one-step method. The oil-in-alcohol highly concentrated emulsions were prepared by stepwise addition of the oil phase to the surfactant-alcohol solution and were characterized by optical microscopy and by laser diffraction. The typical structure of highly concentrated emulsions, with close-packed polyhedral droplets, has been observed. Poly(furfuryl alcohol) monoliths were obtained by polymerizing in the external phase of these emulsions. These materials are mainly macroporous and retain the size distribution and morphology from the highly concentrated emulsions. The internal structure of the monoliths was observed by scanning electron microscopy. The images showed an interconnected network with pore size similar to the droplet size of the highly concentrated emulsions used as templates.
新的油包醇高浓度乳液被制备出来，并被用作模板，通过一步法获得了大孔聚糠醇整体柱。油包醇高浓度乳液是通过逐步向表面活性剂-醇溶液中添加油相来制备的，并通过光学显微镜和激光衍射进行了表征。已经观察到具有紧密堆积多面体液滴的典型高浓度乳液结构。聚糠醇整体柱是通过在这些乳液的外相中聚合而获得的。这些材料主要是大孔的，并保留了高浓度乳液的尺寸分布和形态。通过扫描电子显微镜观察了整体柱的内部结构。图像显示了具有类似高浓度乳液模板液滴尺寸的孔的相互连接的网络。
