“…This suggests a reduction of particle size. Similar results were reported in the literature for kaolinite clay treated with DMSO [ 49 ]. Since the layered structure of clay did not vanish, only cations were displaced by DMSO and no other structural changes occurred in clay.…”

This research endeavour aimed to explore the potential of a native, nonedible and low market value plant feedstock, i.e., Saccharum munja for green synthesis of woodware materials and improve its features by incorporating an economical blending material. A significant amount of furfural, i.e., 58%, was extracted from Saccharum munja through the modified acid digestion method. Extracted furfural was reacted with phenol to prepare phenol-furfural resin, an alternative to phenol-formaldehyde resin but with no harmful effects for humans. The synthesized resin was also blended with montmorillonite clay after modification via Dimethyl Sulfoxide (DMSO) treatment for improved thermo-mechanical properties. These resins and composites were characterized by XRD, SEM, and FTIR spectroscopy. Resultant resins and composites were further employed as a binding agent to make high-pressure composite from leftover plant residue by hot-press method. The resultant product was subjected to TGA analysis and furnished high value of degradation temperature (Tdeg), i.e., 607 °C. Prepared high-pressure composite samples were mechanically tested through compression tests by Tinius Olsen Testing Machine and hardness tests by Rockwell Hardness Tester. Its tensile strength value was 58.3 MPa while hardness value was found to be 64 RHB which was greater than mild copper with hardness value 48.9 RHB. Thus, green high-pressure composite material was successfully developed by employing Saccharum munja and montmorillonite clay while no toxic resin was used, nor was any residue left over.

“…No particleparticle and strong polymerparticle interactions are taken into account in this model. However, some undesirable phenomena such as the weak dispersion of nanoparticles or poor exfoliation of clay platelets, the various values of length and thickness of platelets, the aggregation/agglomeration of nanoparticles especially at high nanofiller content in ternary samples, the poor interfacial adhesion at the polymerfiller interface and the particleparticle interaction are shown in polymer nanocomposites in practice [26,27]. One or more of the above phenomena is enough to decrease the modulus of nanocomposites, which results in the low modulus compared to the prediction of the simplified MoriTanaka model.…”

Antimicrobial resistance is the leading cause of burden on healthcare sector. There is scientific challenge of developing new functional material as a platform to prevent and treat viral and microbial infection and cosmetic utility. In material chemistry, there is progress in the development of functional material with advent of nanotechnology with aid of synthetic organic chemistry. The properties and application of material can be changed significantly by modification of the surface functional groups (namely, COOH, HO, NH2OH, SO4,), formation of composite with inorganic material and incorporation of active pharmaceutical agents. In antibacterial application functional material of copper, silver, gold, platinum, tin, iron, cobalt, ruthenium, zinc and pharmaceutical antimicrobial agents found utility in the treatment of bacterial and hospital acquired infection with different resistant strains of microorganisms. In antiviral application many functional materials have been shown to possess remarkable antiviral ability like quantum dots, gold and silver nanoparticles, nanoclusters, carbon dots, graphene oxide and silicon materials. The polymers and dendrimers functionalized with USFDA approved antiviral agent also has potential therapeutic outcomes. Despite their difference in antiviral mechanism and inhibition efficacy, these functional material structures have unique features as potential antiviral candidates. In cosmetic applications functional material based on mica, sericite, fullerene, charcoal, peptides, mineral, lipids, glucocorticoid, nanocellulose hybrid material are extensively used. In this review, we have highlighted early promise and prospects of functional material for cosmetics, antibacterial and antiviral applications, advantages and disadvantages, Patent scenario, current challenges for translation into commercial products.
