Synthesis and Self-Assembly Characteristics of Brush Block Copolymers in Complex Nonlinear Topology

第三年继续发展新型铁电数字存储系统和新型氧基共轭基团聚合物。新型氧基共轭聚合物的合成和表征已经成功，并在不同薄膜厚度下测量了其电阻记忆行为。为了了解电活性侧链中氧原子的位置和数目与电阻记忆行为之间的关系，对电压-电流（I-V）测量进行了仔细的分析。通过分析，所有的聚合物似乎都存在一个四阶段的传导机制，我对这种新型聚合物的传导机制提出了一个新的理论。目前，对含氧聚合物的研究内容进行了总结，并正在向国际学术期刊投稿。新型铁电数字存储聚合物的研究正稳步取得进展。结果表明，铁电性的大小取决于聚合物的全氟电刷的长度，并合成了一些具有更大全氟电刷长度的聚合物，以研究其化学结构与自发极化行为的关系。已经获得了额外的测量和表征，以准备该系统的几个手稿。目前，该系统的手稿正在准备出版。

The third year continued the development of novel ferroelectric digital memory system and novel polymers with oxygen-based conjugated moieties.The synthesis and characterization of novel polymers with oxygen-based conjugated moieties have been confirmed successful previously and the resistive memory behavior was measured in various thin film thicknesses. In order to comprehend the correlation between the position and number of oxygen atoms in the electroactive side chains to the resistive memory behavior, a careful analysis of the voltage-current (I-V) measurements was done. Through the analysis, a four stage conduction mechanism seemed to be present in all of the polymers and I have developed a new theory on the conduction mechanism for the novel polymers. Currently, the research contents of the oxygen containing polymers are summarized and in process of submission to international academic journals.The development of novel ferroelectric digital memory polymer has been steadily making progress. The results are showing that the magnitude of the ferroelectricity is dependent on the length of the perfluorinated brushes of the polymers and some additional polymers with larger variety of perfluorinated brush lengthes have been synthesized for the purpose of investigating the correlation of the chemical structure to the spontaneous polarization behavior. Additional measurements and characterization have been acquired to prepare several manuscripts for this system. Currently, the manuscript for this system is being prepared for publication.
