Flame retardancy in various materials is becoming an increasingly important performance feature. In the textile industries, fire‐related problems have become an important concern over the decade. Herein, the polyvinyl alcohol (PVA) and graphene‐supported material were functionalized with trimethyl phosphate (TMP) for the synthesis of flame retardant (FR) composite material [graphene polymer functionalized trimethyl phosphate (GPTMP)] in the aqueous medium, which improves the stability of cotton fabric against flame. Graphene and PVA fabricated with phosphorus functional groups make the fabric more comfortable against fire and help to avoid further spreading of fire. The composite‐coated fabric sustains for a long time on continuous flame with maintaining its initial shape and size. The GPTMP‐coated fabric shows flame retardancy for up to 540 s on constant flame exposure, whereas control samples such as PVA‐, graphene oxide‐, and TMP‐coated fabrics resist for up to 15, 20, and 14 s, respectively. The limiting oxygen index (LOI) and vertical flammability test (VFT) for synthesized composites were performed to confirm and support the flame retardancy property of GPTMP. The GPTMP shows the 35% LOI value and forms the char length of 2.6 cm during VFT. This work provides a simple and eco‐friendly method to obtain novel GPTMP, which has a high potential as a FR for different fabrics, including cotton. [ABSTRACT FROM AUTHOR]

In this study, we formulated carbon black pigment by using cheap, easily available bio-waste (cow dung). This pigment used in the preparation of conducting paint which showed excellent electrical conductivity may have applications in several fields, such as energy storage devices, antistatic coatings, and electronic circuits. • The Conductive paint (CP) was prepared by using biowaste i.e. cow dung and alkyd resin. • It showed excellent electrical conductivity ∼ 6.84 × 106 S m−1. • CP showed minimum sheet resistance ∼8.61 × 10−7 Ω sq-1. • CP also showed decent energy storage ability i.e. specific capacitance 216 F g−1 at 1 A g−1 current density. • We applied CP in electronic circuit to check real application of conductivity. In this study, we developed a bio-inspired, eco-friendly, and cost-effective conductive paint (CP). Conventionally, carbon-based black pigment (CBP) was derived from cow dung, which is an eco-friendly, easily available, and inexpensive biowaste material. Subsequently, CP has been prepared using as-prepared CBP. Herein, for the first time, we used CBP as a conductive pigment that was mixed with an air-dried alkyd resin as a binder for paint formulation. As the conductive pigment, the CBP interconnected in the paint matrix by forming percolation pathways; this resulted in excellent conductive behavior of the as-prepared CP. The intermolecular interaction between the alkyd resin and the conductive pigment resulted in a CP that exhibited excellent conductivity as well as energy storage ability. The sheet resistance of the CP, studied using a four-probe resistivity method, was ∼8.61 × 10−7 Ω sq-1. The biowaste-derived CP also exhibited a high specific capacitance of 216 F g-1 and a high energy density of 24 Wh kg-1 at a current density of 1 A g-1. The main advantage of our prepared CP is better conductivity than that of carbon black, graphite, graphene, and carbon nanotube. As a result, the prepared CP may have applications in several fields, such as antistatic coatings, energy storage, electromagnetic shielding, and electronic circuits. [ABSTRACT FROM AUTHOR]
