“…However, Demirci et al found that the hydrophilicity of PVC coating can be controlled by allylamine plasma treatment as the contact angle increased with the treatment time [ 44 ]. More recently, it was demonstrated that a silica nano sol and a commercial water-repellent chemical were employed to impart hydrophobic characteristics on a bleached jute fabric [ 45 ].…”

Natural renewable materials can play a big role in reducing the consumption of synthetic materials for environmental sustainability. Natural fiber-reinforced composites have attracted significant research and commercial importance due to their versatile characteristics and multi-dimensional applications. As the natural materials are easily rotten, flammable, and moisture absorbent, they require additional chemical modification for use in sustainable product development. In the present research, jute fibers were treated with rot-, fire-, and water-retardant chemicals and their corresponding polymer composites were fabricated using a compression molding technique. To identify the effects of the chemical treatments on the jute fiber and their polymeric composites, a Fourier transformed infrared radiation (FTIR) study was conducted and the results were analyzed. The presence of various chemicals in the post-treated fibers and the associated composites were identified through the FTIR analysis. The varying weight percentage of the chemicals used for treating the fibers affected the physio-mechanical properties of the fiber as well as their composites. From the FTIR analysis, it was concluded that crystallinity increased with the chemical concentration of the treatment which could be contributed to the improvement in their mechanical performance. This study provides valuable information for both academia and industry on the effect of various chemical treatments of the jute fiber for improved product development.

“…The mask was then partially dried under ambient conditions followed by heating it at 75 °C for 5 min. Next, the mask was sonicated in a hexadecyltrimethoxysilane (HDTMS) solution containing silica nanoparticles for an hour [136]. Finally, the mask was dried at room temperature for 12 h following by curing it at 100 °C for 3 min.…”

Wearing a face mask has become a necessity following the outbreak of the coronavirus (COVID-19) disease, where its effectiveness in containing the pandemic has been confirmed. Nevertheless, the pandemic has revealed major deficiencies in the ability to manufacture and ramp up worldwide production of efficient surgical-grade face masks. As a result, many researchers have focused their efforts on the development of low cost, smart and effective face covers. In this article, following a short introduction concerning face mask requirements, the different nanotechnology-enabled techniques for achieving better protection against the SARS-CoV-2 virus are reviewed, including the development of nanoporous and nanofibrous membranes in addition to triboelectric nanogenerators based masks, which can filter the virus using various mechanisms such as straining, electrostatic attraction and electrocution. The development of nanomaterials-based mask coatings to achieve virus repellent and sterilizing capabilities, including antiviral, hydrophobic and photothermal features are also discussed. Finally, the usability of nanotechnology-enabled face masks is discussed and compared with that of current commercial-grade N95 masks. To conclude, we highlight the challenges associated with the quick transfer of nanomaterials-enabled face masks and provide an overall outlook of the importance of nanotechnology in counteracting the COVID-19 and future pandemics.

“…Moreover, the reported methods involve multi‐steps (less yield and expensive), high temperature process, and hazardous toxic chemicals. Due to harshness of modification techniques, mechanical properties of treated jute fibers are compromised in many cases 20,21 .

Hydrophobization of hydrophilic jute fiber, is of great importance as it can expand the applications of jute fiber in many fields. This work reports the hydrophobization of jute fiber by high‐energy radiation treatment which is an easy, single‐step, economical, and environment friendly method. Surface wettability of hydrophilic jute fiber is tuned by attaching long chain hydrocarbon molecules, namely butyl methacrylate, octyl acrylate and lauryl methacrylate, using gamma radiation. Lauryl methacrylate is found to be the most suitable agent among the molecules used for generating desired extent of hydrophobicity. Important reaction parameters, namely total dose, dose rate, monomer concentration, and solvent composition are optimized to achieve the desired degree of modification, for imparting hydrophobicity. Mechanical and thermal analysis reveals that there is no considerable damage to the base structure of fibers during modification. Scanning electron microscopy (SEM) is supporting evidence of the intactness of fiber after modification. The successful grafting of jute fiber has also been evidenced by SEM. This lauryl methacrylate modified jute can separate oily toxic liquids from aqueous media. The modified jute fiber may get enhanced applications in various fields.
