    Low density isotropic pyrocarbon (LDIP) of a novel "litchi" hierarchical structure with a high degree of crystallinity and graphitization was prepared by a simple, catalyst-free chemical vapor deposition method. The fabricated LDIP coating surface exhibits highly durable and robust superhydrophobic, self-cleaning, water and corrosive liquids repelling and oil-water separating properties. Moreover, the antifouling/antibacterial properties and biocompatibility of LDIP were investigated. The LDIP coated surface can not only effective prevent protein and bacterial (Gram-negative E. coli) adhesion but also has good biocompatibility. This new type of carbon material has great promise for potential applications in waste water treatment and biomedical fields. (c) 2019 Elsevier Ltd. All rights reserved.
