“…Egg white protein contained amino acids, so that CT W spectra showed two new peaks at 1630 cm -1 and 1525 cm -1 indicating amide-I and amide-II (Bosco et al 2013). In case of CT HA , a new peak appeared at 980 cm -1 for P=O due to the presence of phosphorous content in hypophosphorous acid (Yu et al 2017). According to CT W and CT HA spectra, in combined spectra of egg protein and HA (CT W+HA ) the three peaks found at 1630 cm -1 , 1525 cm -1 and 980 cm -1 would be amide-I, amide-II and P=O.…”

Egg white proteins (W) in combination with hypophosphorous acid (HA) were investigated for making flame retardant coating over cotton fabric adopting layer by layer (LbL) assembly technique. A novel phosphorous-nitrogen based non-inflammatory pathway was produced due to strong electrostatic interactions between egg white protein and HA. The coated cotton fabric was characterized using FESEM, ATR-FTIR, TGA and flame tests. Vertical flame test (VFT) and BS EN ISO 15025 tests were performed to understand the combustion pattern of coated fabric. The cotton fabric coated with egg white protein followed by HA (CTW+HA) showed self-extinguish properties with fragile char structure, whereas uncoated fabric was completely burnt with ash residue. Thermogravimetric analysis revealed that initial decomposition temperature of coated fabric got lowered but raised the char residue at 800 ℃. Moreover, surface morphology after VFT of CTW+HA showed swollen char structure that prevented the interaction of combustible products with oxygen and heat. Thus, the developed coating could serve as excellent fire retardant due to the synergistic effect of HA and egg white protein.

“…Bamboo is a natural polymer material and a rich natural resource in the Asia-Pacific region (Sharma et al, 2015a). As it has the advantages of fast growth, high yield, and excellent mechanical properties, bamboo has been widely used in the production of bamboo-based composites, for example, laminated bamboo board, bamboo plywood, bamboo particleboard, and bamboo scrimber (Verma and Chariar, 2012;Yu et al, 2017a;Zhang et al, 2019). In addition, due to its characteristic appearance, bamboo has been used as a decorative material for buildings (Hu et al, 2012).…”

Bamboo is a rich natural resource in the Asia Pacific, and it is widely used in the construction and decoration industry. Meanwhile, bamboo is an extremely combustible natural polymer material. Herein, the bamboo slices were treated with melamine and phytic acid using layer-by-layer (LBL) assembly technology to improve their flame retardancy properties. The morphology and chemical composition of untreated and treated bamboo slices were measured by scanning electron microscopy equipped with energy dispersive X-ray analysis and Fourier transform infrared spectra. The results showed that two-dimensional melamine–phytate (MP) nanoflakes were successfully formed and deposited on the bamboo surface. The deposition of the MP coating caused the earlier degradation of the bamboo to form char, according to thermogravimetric analysis. The peak heat release rates of the treated bamboo slices were reduced by more than 28% compared to those of the untreated ones. The MP coating promoted the formation of thermally stable char, which was responsible for the significant improvement in flame retardancy. Besides, the char layer with excellent thermal resistance performed a vital role in suppressing flame spread.

“…Hu et al constructed Chitosan/Melamine/Phytic acid coating on the surface of ramie fabric by layer-by-layer (LbL) assembly method to achieve flame retardancy of the LbL-modified fabric reinforced unsaturated polyester resin (UPR). 4 Song et al realized the vertical growth of layered double hydroxides (LDHs) on the surface of ramie fabric through a facile hydrothermal reaction to reach the aim of improving flame retardant property and mechanical property of UPR composites. 5 Carosio et al coupled LbL with UV-curing processes to construct aliphatic acrylic polyurethane latex/ammonium polyphosphate (APP)/chitosan 3 bilayers coating on the surface of cotton fabrics to achieve cotton selfextinguishment, and further constructed Octa-ammonium POSS/ sodium montmorillonite clay coatings on polyester fabrics by LbL assembly to suppress melt dripping phenomenon and improve washing durability.…”

The present work demonstrates a surface pretreatment of reducing assembly layers for flame retardant modification of ramie fabric used by layer-by-layer (LbL) assembly. In order to achieve this goal, low-temperature plasma (LTP) pretreatment was chosen. Attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR) and scanning electron microscope (SEM) were used to confirm the effect of LTP pretreatment on polyethylenimine/ammonium polyphosphate (PEI/APP) flame retardant coating constructed on the surface of ramie fabric using LbL assembly. The thermal property and flame retardancy of PEI/APP coated ramie fabrics were analyzed by TG, LOI, UL94 vertical burning, and cone calorimeter tests. The results indicated that the decomposition rate of ramie fabrics was reduced and the char forming ability at high temperature was improved by PEI/APP coating on the ramie surface. Its LOI increased markedly to 30.6% and ramie fabric achieved selfextinguishing effect. Meanwhile, LTP-O 2 -(PEI/APP) 20 ramie fabric exhibited the low flammability and high fire safety. It was proved that LTP pretreatment under oxygen atmosphere could endow ramie fabric with better flame retardancy due to more PEI/APP adsorbed on its surface. These findings have significant implications for the application of LTP pretreatment to flame retardant modification of ramie fabric by LbL assembly.
