“…3 Therefore, several chemical, biological, and physiological methods are followed to process the polluted water containing the dye waste. [4][5][6] Adsorption, flocculation, precipitation, coagulation, photocatalysis, electrodialysis, reverse osmosis, and ion exchange chromatography are some of the adopted methods. 7 Most of the processes of wastewater purification cause adverse effects such as secondary pollution due to the accumulation of high sludge and residual metal ions in the treated water system.…”

In the present work, a magnetized multiwalled carbon nanotube dispersed in chemically cross‐linked gaur gum was developed as a nano‐composite adsorbent material for the removal of dye from wastewater. The gaur gum, a bio‐macromolecule was chemically modified by cross‐linking with methylene bis‐acrylamide in the presence of sodium hydroxide as a novel approach to prepare the gel matrix. The magnetite nanoparticles loaded multiwalled carbon nanotubes were dispersed in methylene bis‐acrylamide cross‐linked gaur gum gel during gelation. The nano‐composite was characterized for morphological, spectral, and analytical data. The solid form of the nano‐composite was evaluated as an adsorbent material for the treatment of water containing methylene blue dye molecules as pollutants by the spectrophotometric method. Adsorption isotherm studies suggested that the Freundlich model was the befitting model for adsorption, indicating the multilayered adsorption and the kinetic study revealed the adsorption to occur by a pseudo‐second‐order kinetic process. The novel nano‐composite is found to be a promising material for the adsorptive removal of dye molecules from dye‐contaminated wastewater. The adsorption capacity was observed to be 11 mg/g of the material.

“…It has found extensive applications in various fields including the national defense industry, civil industry, 3 biomedical engineering, 4,5 water‐lubricated bearings, 6 and so on. PUs are highly versatile materials known for their durability, abrasion resistance, flexibility, thermal insulation, flame retardant properties, and electrical insulating properties 7–10 . In general, the abundant hydrogen bonding between urethane distinguished the microphase separation as hard segment (HS) and soft segment (SS), 11 consequently endowing PU with unique properties, 12 which could be customized by molecular engineering a library of raw materials.…”

Polyurethane (PU) materials with high strength, toughness, anti‐wear properties, and high heat resistance are in high demand for dynamic sealing applications. In this study, a series of high‐performance crosslinking polyurethanes (CPUs) were prepared by pre‐polymerization of polycarbonate diol (PCDL) with toluene‐2,4‐diisocyanate (TDI), followed by crosslinking with trimethylolpropane (TMP). The molar ratio (R) of PCDL/ TDI and the degree of cross‐linking were found to significantly affect the microphase separation. The results indicate that as the R‐value increases, the transition temperature of CPUs increases from 6.0°C to 82.4°C, and the tensile strength increases from 21.1 ± 2.5 MPa to 46.0 ± 3.6 MPa. Moreover, the CPUs exhibit excellent heat resistance (with a heat resistance index of ~150°C) and hydrolysis resistance, attributed to the high crystallinity of PCDL and the synergistic effect of chemical crosslinking. Additionally, the CPUs demonstrate low friction coefficient (COF = 0.01–0.062), exceptional anti‐wear properties (Akron wear, 0.11–0.07 cm3/1.61 km), and outstanding fatigue resistance. These desirable characteristics make CPUs suitable for use as dynamic sealing or lubricating materials in harsh conditions, thereby extending the service life of seals and preventing leakage and other related issues.
