Abstract
Abstract Resorcinol-formaldehyde aerogels (RF AGs) of two density values (0.15 and 0.64 g/cm3) were acylated by an excess of perfluoroalkane carboxylic anhydrides (RFCO)2O (R = CF3, C8F17). After acylation by perfluorononanoic acid anhydride the resulting fluorinated aerogels retained high specific surface area (270−345 m2/g) and acquired high hydrophobicity – water drop contact angle value reached 145°. Besides, these samples demonstrated low water vapour and liquid water absorption.
