“…From the TG curves, it is observed that the combustion of CNT/cellulose sheet is 22% less than that of the pure cellulose sheet. This result signifies that the thermal stability of the sheet is improved by adding MWNTs [26,27]. There is also a hump shape peak at 463 ∘ C on the CNT/cellulose curve before the final combination peak which corresponds to the combustion of the gelatin [18].…”

Multiwalled carbon nanotube/cellulose composite papers have been prepared by mixing the cellulose with MWNT/gelatin solution and drying at room temperature. The CNTs form an interconnected network on the cellulose paper and as a result CNT paper sheet exhibits enhanced electrical properties and thermal stabilities. It is found that both sides of CNT paper sheet have the uniform electrical conductivities. The sheet exhibits strong microwave absorption in the microwave range of 10.5 GHz. The CNT/cellulose paper is as flexible and mechanically tough as the pure cellulose paper. This work provides a novel and simple pathway to make CNT/cellulose sheet as multifunctional biomaterials for electronic, magnetic, semiconducting, and biotechnological applications.

“…Figure showed the TG and DTG curves of control cotton and the PAN treated cotton under nitrogen atmosphere. The main mass loss of the cotton fabric prior to the initial degradation temperature came from the volatilization of free water in the fabric . When the temperature reached 335.1 °C, the mass of the control cotton began to decrease rapidly, and the mass loss rate slowed down at 400.3 °C.…”

[42] When the temperature reached 335.1°C, the mass of the control cotton began to decrease rapidly, and the mass loss rate slowed down at 400.3°C. In this temperature range, the sample quality loss was about 76.6%.…”

A Phosphorous‐Aluminium‐Nitride Synergistic Flame Retardant to Enhance Durability and Flame Retardancy of Cotton

et al. 2019

In this paper, a Phosphorous ‐ Aluminium ‐ Nitride synergistic flame retardant (PAN) was synthesized by phosphoric acid, glycerol, aluminium sulfate and urea, though a one‐pot process. The PAN was durably grafted onto the surface of cotton fabric by the simple process of soak‐dry‐cure. At the same time, the synergistic effect of the aluminium element and Phosphorous ‐ Nitrogen flame retardants (PN) was investigated. The flame‐retardant effect is the best when the conttent of alumium is 2.5 mol% (percentage of phosphoricacid) in PAN. The analyses of FTIR and XPS results suggested that PAN was grafted onto the cotton by forming a strong P−O‐C covalent bond on the surface of fiber. The SEM and Whiteness test proved that the flame‐retardant finishing cotton fabric do possess good morphology and whiteness. The thermal stability and flame retardancy of the PAN treated cotton fabric were assessed by TG and vertical flammability test. Then, found the aluminium sulfate in PAN had synergistic effect, and the PAN had significant flame retardancy in application.

Polymer wrapping methods have been used to disperse carbon nanotube (CNT) by using gelatin, an environment-friendly and easily decomposable biopolymer. The amino acid chain of gelatin becomes immobilized by the physical adsorption in the side wall of the CNTs through hydrophobic-hydrophobic interaction and results in the untangling of the CNT bundles. The dispersed solution remains stable for more than a month. Furthermore, this technique does not affect the physical properties of CNTs while enabling their dispersion in aqueous solutions. In addition, gelatin can be easily removed from the nanotubes after the dispersion of nanotubes by heating in water and filtration. Gelatin-dispersed CNTs are homogeneously mixed with the cellulose suspension and dried at room temperature to produce CNT/cellulose composite paper sheet. Adding multiwalled carbon nanotubes (MWNTs) in composite improves the mechanical, thermal, and electrical properties of cellulose. SEM investigation confirms the homogeneous distribution of MWNTs in the cellulose, which can be attributed to the improvement of its characteristics. Both sides of the CNT/cellulose sheet show uniform electrical conductivity, which is enhanced by increasing the MWNTs' content. IR image of the sheet clearly shows the temperature homogeneity of the surface. Thermal stability and the flame retardancy of the sheet are also found to be improved. The sheet has also strong absorbing of electromagnetic waves, which make them important for microwave technology applications.
