项目摘要

Think about how useful braiding has been on the macroscopic scale in the context of the evolution of human society. The transformation of natural fibres into ropes, plaits and weaves has given rise to huge advances in construction, exploration, textiles and art. In biology the way in which fibre entangle is also hugely important. Tangled or entwined fibres are found in DNA and in serious protein misfolding diseases such as amyloidosis, and are responsible for the symptoms of old age. Fibre entanglement is also of huge industrial importance in polymer chemistry (entanglements create weak points that make your polythene bag tear, for example) and fibrous assemblies are found in gels, lubricants and creams (think hair gel, drilling 'mud', contact lenses and pill coatings, for example). In Nature fibres allow climbing plants to encircle a support according to quite subtle rules that are not readily apparent. Many of these fibrous assemblies occur chaotically and it is difficult to predict what the properties of the bulk material will be even with a good understanding of the fibrous components. This research project aims to create controlled, well-defined fibres whose evolution into complex (sometimes called 'emergent') assemblies can be studied in detail. We will examine how a fibre forms through aggregation of molecules and scrolling of molecular sheets, how it entwines through surface attachment and braiding, and how it branches through defect formation and entanglement, ultimately giving rise to the natural and everyday materials we are familiar with in the world around us.

想一想在人类社会发展的背景下，编织在宏观规模上的有用程度。天然纤维转变为绳索，辫子和编织，这在建筑，勘探，纺织品和艺术方面取得了巨大进步。在生物学中，纤维纠缠的方式也非常重要。在DNA和严重的蛋白质错误折叠性疾病（如淀粉样变性）中发现了纠结或缠绕的纤维，并负责老年症状。纤维纠缠在聚合物化学中也具有巨大的工业重要性（例如，纠缠产生的弱点，使您的聚苯袋撕裂，例如，纤维化的组件在凝胶，润滑剂和乳霜中发现（例如，凝胶，凝胶，泥浆“泥浆”，接触透镜和药丸涂料）。在自然界中，允许攀岩植物根据不容易明显的微妙规则包围支撑。这些纤维组件中的许多都混为一谈，即使对纤维组件有很好的了解，也很难预测散装材料的特性。该研究项目旨在创建受控的，定义明确的纤维，这些纤维可以详细研究，其演变成复杂（有时称为“新兴”）组件。我们将通过分子的聚集和滚动分子片的滚动来研究纤维如何通过表面依恋和编织的滚动以及它如何通过缺陷形成和纠缠而分支，最终产生了我们周围世界上我们熟悉的自然和日常材料。
