A flame retardant coating based on amino acid and phytic acid for cotton fabrics
The effective and eco-friendliness flame retardants for fabrics are increasingly being prioritized. In this study, cotton fabrics were coated with dimethyl phosphite lysine (LP) and phytic acid (PA) to create an eco-friendly and high-efficient fireproof barrier through strong electrostatic attraction and hydrogen bond assembly. The flame-retardant property of the coated cotton fabrics (C/LP10/PA) demonstrated a significant improvement, as evidenced by a limiting oxygen index of 40.2 % and an inherent ability to self-extinguish upon removal of the fire source during vertical burning tests. Furthermore, the synergistic flame-retardant effect of LP and PA resulted in a reduction of 74 % in peak heat release rate and 21 % in total heat release for C/LP10/PA compared to pure cotton. However, the smoke release of C/LP10/PA was increased due to the incomplete combustion. Moreover, the charring process was significantly enhanced in C/LP10/PA with a char residue weight percentage of 26.0 %, from 7.0 % for pure cotton fabric. The analysis of residual char after burning and gaseous products generated during the decomposition process demonstrated that LP/PA coating exhibited flame-retardant properties in both condensed and gas phases. Generally, this work presents a feasible and eco-friendly method for achieving flame retardancy in cotton fabrics.
期刊介绍：
Polymer Degradation and Stability deals with the degradation reactions and their control which are a major preoccupation of practitioners of the many and diverse aspects of modern polymer technology.
Deteriorative reactions occur during processing, when polymers are subjected to heat, oxygen and mechanical stress, and during the useful life of the materials when oxygen and sunlight are the most important degradative agencies. In more specialised applications, degradation may be induced by high energy radiation, ozone, atmospheric pollutants, mechanical stress, biological action, hydrolysis and many other influences. The mechanisms of these reactions and stabilisation processes must be understood if the technology and application of polymers are to continue to advance. The reporting of investigations of this kind is therefore a major function of this journal.
However there are also new developments in polymer technology in which degradation processes find positive applications. For example, photodegradable plastics are now available, the recycling of polymeric products will become increasingly important, degradation and combustion studies are involved in the definition of the fire hazards which are associated with polymeric materials and the microelectronics industry is vitally dependent upon polymer degradation in the manufacture of its circuitry. Polymer properties may also be improved by processes like curing and grafting, the chemistry of which can be closely related to that which causes physical deterioration in other circumstances.
