Description of the structure-property-function (SPF) relations of CNT-doped adhesive composites for the development of functional blocks

Abstract

In novel CNT-enhanced composite materials there has been noted a significant gap between material development and their application in engineering fields. In this context, we apply a function-integration design approach, where we propose a targeted material development and standardization through the adaption of functional blocks. Utilizing the structure-property-function (SPF) relations on the case study of CNT-doped adhesives, we map the internal structure of the system to targeted functions through selected properties. We highlight the influence of volume fraction and aspect ratio of CNTs on the homogenized properties of the composite and their extension on the targeted functions. We conclude that there exists a link between structure, property and function in a form which can be characterized as a functional block. Such approach can provide way to a standardized material selection, succeeding in a more function-oriented design of materials.
