Multifunctional fabrics of high durability through a scalable and eco-friendly technique remains a great challenge hindering their commercialization. In this work, we report a facile synthesis technique for the fabrication of superhydrophobic antibacterial fabrics by employing fluorine-free silane coupling agents as cross-linkers for enhanced durability. Three silane cross-linkers, Aminoethylaminopropyltrimethoxysilane (AEAPTMS), Aminopropyltriethoxysilane (APTES), and Methacryloyloxypropyltrimethoxysilane (MPTMS), have been investigated. During the fabrication, a low surface energy polymer, polydimethylsiloxane (PDMS) was first deposited on cotton fabrics. Subsequently, antibacterial copper oxide (CuO) nanoparticles were anchored on the PDMS coated fabrics using the silane cross-linkers. The as-prepared fabrics displayed high superhydrophobicity and antibacterial performance with water contact angle (WCA) > 153°, water shedding angle (WSA)
