项目摘要

Without exception the first large scale application proposed for most nanomaterials, including the graphene family of materials is as a functional filler for composite applications. To date, the tendency has been to add poorly characterised graphene to the polymer of interest using different mixing devices, more often using mixing methods not representative of that used in industry. Unsurprisingly, this approach has significantly hindered the full exploitation of these composite materials. Critically, the promotion of interfacial interactions between the graphene and polymer is widely ignored by many researchers. Tailoring the properties of such composites is dependent on effective dispersion and distribution of the graphene in the polymer/rubber of interest, the extent of which determined by a combination of favourable interfacial interaction and efficient mixing of the composite component. In this project, the dispersion of and interfacial interaction between model graphene(s) and thermoplastic elastomers (TPEs) and Thermoplastic vulcanizates (TPV)s from both petrochemical and bio-derived sources will be studied. TPEs/TPV's are multiphase systems and the controlled localisation of the graphene in different phases will be examined using a range of spectroscopic and microscopic techniques. The relationship between processing, composite structure and properties will be investigated where the, ultimate aim of the project is to gain a fundamental understanding of the factors that control localization of unfunctionalized and functionalized graphene(s) in two phase polymer systems such that the properties of the TPE/TPV can be tailored.

无例外，针对大多数纳米材料（包括石墨烯材料家族）提出的第一个大规模应用是复合应用的功能填充物。迄今为止，趋势是使用不同的混合设备在感兴趣的聚合物中添加不良特征的石墨烯，更经常使用不代表行业中使用的混合方法。毫不奇怪，这种方法极大地阻碍了对这些复合材料的全面利用。至关重要的是，许多研究人员广泛忽略了石墨烯与聚合物之间的界面相互作用。定制这种复合材料的性质取决于石墨烯在感兴趣的聚合物/橡胶中的有效分散和分布，该聚合物通过有利的界面相互作用和复合成分的有效混合而确定的程度。在这个项目中，将研究模型石墨烯与热塑性弹性体（TPE）和热塑性硫化物（TPV）S之间的分散和界面相互作用。 TPE/TPV是多相系统，将使用一系列光谱和微观技术检查石墨烯的受控定位。将研究处理，复合结构和属性之间的关系，该项目的最终目的是对控制不官能化和功能化石墨烯在两个相聚合物系统中的定位的因素进行基本理解，从而使其在两个相聚合物系统中的定位，从而使其在两个相聚合物系统中的特性，以便可以定制TPE/TPV。
