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

项目编号：CTS-9806004项目负责人：Rezac A power奖。该研究将研究从混相和非混相聚合物共混物中形成微孔聚合物结构的潜力。通过控制聚醚砜/第二聚合物/ n -甲基吡咯烷酮/水的分子量，研究了聚醚砜/第二聚合物/ n -甲基吡咯烷酮/水的模型体系。在低分子量的情况下，系统是可混溶的，并且抗塑剂的行为可以建模。随着分子量的增加，混相间隙减小，然后消失。热力学平衡图将使用云点技术进行评估。所得聚合物结构的形态和聚合物相行为将被评估并与加工条件相关联。这个power奖是为了帮助PI在一个对她的专业发展至关重要的新领域发展专业知识。

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.
