Graphene is a two-dimensional carbon based material with unique properties, such as electrical and thermal conductivity. When a textile is coated with graphene, it becomes conductive, while remaining low weight, soft, breathable, flexible, and stretchable. The purpose of this thesis is to investigate what products are suitable to be made with graphene textiles, by using the method Material Driven Design (MDD). Reflections are also made to determine how this method is affected by being applied to a two-dimensional material. To help with this, three kinds of graphene textiles from the company Grafren AB are investigated; conductive textiles, heatable textiles, and textile sensors. The product goal is to develop a portfolio containing 5-8 conceptual products based on these graphene textiles. The process includes conducting an investigation of the technical properties of the material, a user study, and a benchmarking study. This is done to understand the limitations and opportunities of the material, how it is perceived, and what similar materials there are on the market. After that, the material's characteristics are reflected upon to establish a vision for how it should be used in future applications. Then, to follow that vision, a user study is conducted to investigate how people perceive different materials and products, in order to create design guidelines to ensure that the material and product are perceived as intended. Next, concepts are developed according to the previously determined guidelines. To achieve this, idea generating workshops are conducted, where 14 concepts are selected for further development. The portfolio is then created, meant to inspire further usage of the material. It contains the following seven concepts. A heatable textile meant for cooking on camping trips. A fabric containing sensors that can notify when it is damaged. A keyboard made of fabric, for an easy and comfortable use and transportation. A stroller with sensors and heaters, for a more comfortable and safe user experience. A conductive jacket that can electrocute mosquitoes that come in contact with it. Pressure sensors in a carpet that can keep track of the people inside and provide assistance in emergencies. Gloves with sensors in them that can translate sign language live to text or speech. Since MDD heavily focuses on the sensorial qualities and physical characteristics of the material, the method needs to be adapted to become useful when working with such a versatile two-dimensional material. Fortunately, most adaptations can be made fairly easily. The timing of each step should also be considered, to ensure that the vision and guidelines can be made specific enough to be useful.
