POWRE: Microporous Polymer Blends: Influence of Polymer/ Solvent/Non-Solvent Intractions on Structure

摘要 提案编号：CTS-9806004 主要研究者：M. Rezac 一个权力奖。这项研究将探讨从可混溶和不混溶的聚合物共混物形成微孔聚合物结构的潜力。 将通过操纵第二聚合物的分子量来检查聚醚砜/第二聚合物/N-甲基吡咯烷酮/和水的模型系统。在低分子量下，体系是可混溶的，并且可以模拟抗增塑剂的行为。随着分子量的增加，相容性间隙将减小，然后消失。将使用浊点技术评估热力学平衡图。将评价所得聚合物结构的形态和聚合物-聚合物相行为，并将其与加工条件相关联。 这个POWRE奖是为了帮助PI在一个新的领域发展专业知识，这对她的专业发展至关重要。

ABSTRACT Proposal Number: CTS-9806004 Principal Investigator: M. Rezac A POWRE Award. The study will examine the potential for forming microporous polymer structures from both miscible and immiscible polymer blends. A model system of polyethersulfone/a second polymer/N-methyl-pyrrolidone/and water will be examined by manipulating the molecular weight of the second polymer. At low molecular weights the systems are miscible and the behavior of antiplasticizers can be modeled. As the molecular weight increase the miscibility gap will decrease and then disappear. The thermodynamic equilibrium diagram will be evaluated using the cloud point technique. The morphology and polymer-polymer phase behavior of the resultant polymer structure will be evaluated and correlated with processing conditions. This POWRE award is to assist the PI to develop expertise in a new area which is critical to her professional development.
