Abstract In order to endow cotton fabrics with flame retardancy and antistatic properties, graphene, casein, and ammonium polyphosphate were deposited on their surface via layer-by-layer assembly. Asprepared cotton fabrics were characterized by Fourier transform infrared spectroscopy and scanning electron microscopy. Meanwhile, the flame retardancy and antistatic property of cotton fabrics were investigated in detail. The limiting oxygen index of as-crafted cotton fabrics increased from 18.0% to 23.6%. The antistatic property of the coated cotton fabrics can be proved by its lower (4.974 9 104) surface resistance than that of pristine ones (1.011 9 1010). This work provides a new understanding for the design and development of novel and large-scale fabrication of multifunctional cotton fabrics.

Introduction To date, cotton fabrics have been widely used in clothing, decoration, and other industries due to their comfort (Brillard et al. 2017). Especially, there are numerous active hydroxyl groups in chemical structure of cotton fabrics, which makes them easy to functionalize and ensures the adhesion and distribution of coatings on the surface (Li et al. 2010). Therefore, functional cotton fabrics should be developed for better use in life. With the occurrence of fire incidents every year, the preparation of flame-retardant cotton fabrics has become an important issue. Thus, how to develop an eco-friendly method to endow cotton fabrics with excellent flame retardancy remains a problem. According to the literature, a variety of materials including halogen (Davies et al. 2002), DOPO (Vasiljevic´ et al. 2015), graphene (rGO) (Lu and Hamerton 2002) etc. have been employed to give flame retardancy to cotton fabrics. For example, rGO, which has two-dimensional (2D) monolayer sp2hybridized carbon lattice structure, has been successfully applied in various fields owing to its superior electrical conductivity and excellent flame retardancy (Ji et al. 2019). In particular, on account of the high thermal stability and melting point (of nearly 2000 °C), rGO can be used as an inorganic flame retardant material (Ji et al. 2019). To date, most research has focused on developing its flame
