首次采用非溶剂诱导相分离法（NIPS）制备了具有三维连续连通多孔结构的聚碳酸酯（PC）整体材料。用SEM观察了合成的整体材料的形貌，用BET法测定了其比表面积，用DSC测试了其热性能。通过改变聚合物浓度和分子量、静置温度和溶剂组成等制造参数，可以容易地控制整料的孔和骨架尺寸。PC整料具有相对大的表面积和232 ℃的尖锐熔点。这些具有高热稳定性的整体材料可以提供各种潜在的功能材料应用。(C)2012爱思唯尔有限公司保留所有权利。
Polycarbonate (PC) monoliths with three-dimensional continuous interconnected porous structure in a single piece are fabricated via non-solvent induced phase separation (NIPS) for the first time. The morphology of fabricated monolith is observed through SEM, the surface area is determined by BET method and the thermal property is measured via DSC. The pore and skeleton sizes of the monolith are readily controlled by varying the fabrication parameters such as the polymer concentration and molecular weight, the standing temperature and the solvent composition. The PC monolith possesses relatively large surface area and sharp melting point at 232 degrees C. These monoliths with high thermal stability can offer various potential applications of functional materials. (C) 2012 Elsevier Ltd. All rights reserved.
