Abstract Scope A single-step synthesis of super-water-repellent oil sorbents based on cellulose acetate mats is reported in this paper. Key phenomenological mechanisms involving roughness and changes in chemistry are used to describe the change in hydrophobic behavior. Contact angle calculations followed by Cassie’s model contact angle prediction shows roughness alone is not capable of producing super-hydrophobicity exhibited by as-spun mats. FTIR of spin coated and electrospun mats shows a significant difference in stretching of hydroxyl bonds of two materials. Hydroxyl group which add to the overall polarity of surface causes hydrophilicity of the material. Therefore, We propose, electrospinning process not only creates a rougher surface but also alters the chemistry of the electrospun cellulose acetate mats which ultimately gives rise to the reported hydrophobicity. The as-spun mats were tested as oil sorbent mats. The as-spun mats were capable of absorbing thirty times their weight in oil demonstrating their application for oil-water remediation
