The sheets of graphene oxide (GO) were sonicated, linked with carbon nanotubes (CNTs), and doped with AgI (G-CNT/AgI). X-ray diffraction studies reveal that the crystalline nature of nanocomposites diminishes as the carbon content rises. Analyses using SEM and TEM reveal that the shape and size of the materials are cubic and 20 nm. The EDX anal. revealed that the samples included solely Ag, I, and Carbon. The material′s UV-vis absorption spectra result in significant absorption bands that may be seen at 420 nm. After loading G-CNTs into the AgI, the absorption range grew a little, which shows that the G-CNTs are excellent for the nanocomposite′s ability to absorb light. To evaluate the performance of the component, the Methylene blue (MB) dye solution was deteriorated. Within 90 min, the degradation was nearly finished. Due to the formation of a heterojunction between AgI and G-CNT and the subsequent separation of charge carriers, the G-CNT/AgI nanocomposite exhibited exceptional photocatalytic stability after four cycles. As a result, the innovative G-CNT/AgI photocatalyst was a potential component of the waste water purification system.

Recently streamlining wood waste production and promote their recovery and recycling have been popularized with the sustainable utilization of the waste generated in the saw mill to promote sound, sustainable and healthy wood waste management practices. Herein, we report the development of polymer composite from the saw dust as a reinforced filler on the natural non-edible cotton seed oil resin as feedstock amalgamated with the styrene monomer. The prepared virgin polymer saw dust (VPSD) composite holds light weight, low cost, easy handling and storage, enhanced mech. strength, low energy production, eco-friendliness, renewability and sustainable waste management. The reinforced polymer composite material was characterized by spectroscopic and microscopic techniques. The thermal studies of the as-prepared composite shows the extended thermal degradation due to the blending of saw dust into the polymeric process and its mech. study confirms the enhanced stiffness due to the wooden dust. Due to the significant property obtained by reinforcing the saw dust in the natural resin matrix, the process could be used to extend the development of many polymeric feedstocks as a part of sustainable waste management process.

Fiber-reinforced polymer composites have been developed from the reaction of fumarate resin with natural material Perch fiber. The composite material is fabricated by hand layup technique. The fabricated composite material was tested for its mech. properties such as Tensile Strength, Flexural Strength and Impact Strength. The composite specimens for the above-mentioned test were prepared as per the ASTM standards The fiber reinforcement influenced the improvement of mech. properties of polymers and surface morphol. of the polymer was analyzed by Scanning Electron Microscope. Moisture absorption and vibration damping with polymers and its effect on mech. properties can also be studied. Tensile strength, flexural strength and impact strength were observed and compared to each other. Tensile test showed maximum ultimate tensile strength for untreated 80 mm length fiber compared to others. Flexural test showed maximum ultimate flexural strength for untreated 80 mm length fiber compared to others. Impact test showed higher impact energy for treated 40 mm length fiber compared to others.
