Slippery organogels have gained increasing interest as competitive candidates for antifouling applications. However, it remains challenging to develop tough organogels suitable for fouling resistance indynamic and flexible application scenarios. Herein, a kind of physically crosslinked organogels with acombination of desirable properties, including high toughness, transparency, surface slipperiness, andfouling resistance is developed. The representative pAL organogels, constructed by poly(acrylonitrileco-lauryl acrylate) (pAL) copolymer and infiltrated with n-hexadecane as a lubricating solvent, possesshigh tensile fracture stress, fracture strain, Young’s modulus, and toughness of 4.28 MPa, 517%,2.52 MPa, and 11.19 MJ m3. In the organogels, the polar cyano groups from the pAN segments serveas physical cross-linking points, where the synergistic effects played by oleophobic and dipole–dipoleinteractions significantly toughen the materials. Meanwhile, the soft oleophilic poly(lauryl acrylate)chains offer considerable solvent content, giving rise to satisfactory surface slipperiness. Therefore, theorganogels bring about a 57.16% and 81.50% reduction of protein and bacteria adhesion in comparisonto the control. The satisfactory antifouling performance has been further confirmed with Spirulina platensis. It is deemed that this organogel may provide great potential for various applications in the future suchas anti-adhesion materials and self-cleaning coating.
