项目摘要
Objective: To increase our understanding of interactions between colloids and polymers and polyelectrolytes and the association complexation of polymers, polyelectrolytes and other water-soluble substances. These interactions play a key role in many industrial processes and the scientific understanding of these phenomena is at the forefront of colloid and surface science.
Scientific approach: the proposed research can be divided into three related topics, discussed below.
1. Self-assembling polymers, 2. Dissolved cellulose derivatives, 3. Electrokinetics and electroacoustics. We will be extending the self-assembling observed for alternating copolymers to other molecules, such as alternating polypeptides and cellulose derivatives, which are molecules all having the same chirality, for which we expect complete association. Another class of self-assembling polymers are copolymers. We will study the transition between spherical micelles and nanorods (both consisting of a PCL core and a PEO corona) in more detail in able to predict and control the nanorod formation. The use of cellulose is likely to increase, because of its unique biodegradable and biorenewable properties. Many cellulose derivatives can be made in aqueous or non-polar solvents, such as dialdehyde cellulose, di-and tricarboxycellulose, alkylated cellulose, etc. It is proposed to study and characterize these polymers in detail. Cellulose gels will be characterized by electroacoustics. Novelty and expected significance of the research: The work on self-assembly will increase our understanding of self assembly solely governed by pi-stacking, and nanotubes and nanorods can be used as templates for conducting nanostructures. The work on cellulose derivatives can lead to a number of interesting applications, such as e.g. biodegradable superabsorbents and superhydrophobic surfaces, whereas the work on electrokinetics and electroacoustics will increase our understanding of biodegradable cellulose gels, which are likely to find many medical and industrial applications.
目的:加深对胶体与聚合物、聚电解质之间的相互作用以及聚合物、聚电解质等水溶性物质缔合作用的认识。这些相互作用在许多工业过程中起着关键作用,对这些现象的科学理解处于胶体和表面科学的前沿。
科学方法:拟议的研究可分为三个相关主题,讨论如下。
1.自组装聚合物,2.溶解纤维素衍生物,3.电动力学和电声学。我们将把观察到的交替共聚物的自组装扩展到其他分子,如交替多肽和纤维素衍生物,这些分子都具有相同的手性,我们预计它们将完全结合。另一类自组装聚合物是共聚物。我们将更详细地研究球形胶束和纳米棒(都由PCL核和PEO电晕组成)之间的转变,以能够预测和控制纳米棒的形成。由于其独特的可生物降解和生物可再生特性,纤维素的使用量可能会增加。许多纤维素衍生物可以在水或非极性溶剂中制备,如双醛纤维素、二羧基和三羧基纤维素、烷基化纤维素等,建议对这些聚合物进行详细的研究和表征。纤维素凝胶将通过电声学进行表征。研究的新颖性和预期意义:自组装工作将增加我们对仅由pi堆积控制的自组装的理解,纳米管和纳米棒可以用作导电纳米结构的模板。纤维素衍生物的研究可以带来许多有趣的应用,例如可生物降解的高吸水性材料和超疏水表面,而电动力学和电声学的工作将增加我们对可生物降解纤维素凝胶的理解,这可能会发现许多医疗和工业应用。
