项目摘要

Many nanotechnologies rely on materials and surfaces with precise nanoscale patterns of various types. The more types that can be easily fabricated, the greater the flexibility for the design and conception of these nanotechnologies. Nanopatterns are difficult to fabricate cheaply by lithographic techniques, and therefore materials that are capable of self-assembling naturally into desired nanopatterns are heavily researched. Among these materials are block copolymers, particularly in the form of films, which can provide nanopatterned surfaces. In our research, we have shown recently that an easy and cheap film-forming procedure called dip-coating, when applied to block copolymers, can give simultaneous control over film thickness and its patterning in a single step, just by varying the dip-coating speed. We have also obtained extremely thin films with particular patterns, including a square pattern (useful, for example, for nanoelectronics), on a water surface using a so-called Langmuir-Blodgett technique. Based on these very promising results, we propose to develop, in particular, the block copolymer dip-coating technique in various ways to obtain a diversity of nanopatterns. To create and control these patterns intelligently, we want to develop our understanding of the relationship between the patterns obtained and the molecular characteristics of the block copolymer used (often combined with special additives that are an easy way to modify or fine-tune the patterns), the structure of the solutions used, and the experimental dip-coating parameters used. Similarly, we will apply the Langmuir-Blodgett technique to control special patterns. Two areas of applications of our films towards which we will contribute are medical nanobiosensors and nanophotonics. Our research is expected to benefit the development of nanotechnologies in Canada and directly trains HQP in this and related areas.
许多纳米技术依赖于具有各种类型的精确纳米尺度图案的材料和表面。容易制造的种类越多,这些纳米技术的设计和概念的灵活性就越大。纳米图案很难通过光刻技术廉价地制造,因此能够自然自组装成所需纳米图案的材料被大量研究。在这些材料中,嵌段共聚物,特别是以薄膜的形式,可以提供纳米图案的表面。在我们的研究中,我们最近展示了一种简单而廉价的成膜过程,称为浸涂,当应用于嵌段共聚物时,可以通过改变浸涂速度在一个步骤中同时控制膜厚度和图案。我们还利用所谓的Langmuir-Blodgett技术,在水面上获得了具有特殊图案的极薄薄膜,包括方形图案(例如,对纳米电子学很有用)。基于这些非常有希望的结果,我们建议以各种方式发展嵌段共聚物浸涂技术,以获得多样化的纳米图案。为了智能地创建和控制这些模式,我们希望发展我们对所获得的模式与所使用的嵌段共聚物的分子特性之间的关系的理解(通常与特殊添加剂结合,这是一种简单的方法来修改或微调模式),所使用的溶液的结构,以及所使用的实验浸渍涂层参数。类似地,我们将应用Langmuir-Blodgett技术来控制特殊模式。我们的电影应用的两个领域是医学纳米生物传感器和纳米光子学。我们的研究预计将有利于加拿大纳米技术的发展,并直接培养该领域和相关领域的HQP。
