Abstract

The preparation of oleophobic materials coated with a composite based on a multi-layer graphitic scaffolding is reported herein. A range of substrates were employed for this purpose including Kevlar, carbon fibre, glass fibre, nylon and stainless steel mesh. These were utilised, in comparison with f...
