“…Evaluations of surface charge by zeta potential (Figure 3c) have determined that the Clay-MOF composite is positively charged at all pH values (3)(4)(5)(6)(7)(8)(9)(10)(11). The surface charge gradually decreased from + 10.2 mV at pH 5 down to + 0.93 mV at pH 11.…”

“…[3] Despite many attempts at wastewater treatment using the clay minerals and their composites, there are still many shortcomings to overcome. [4] An important issue is the hydrophilic properties of clay minerals, which makes their effective removal of organic pollutants from wastewater rather questionable. [5] Therefore, surface modification and/or hybridization of clay-based adsorbent are vital issues for efficient wastewater treatment.…”

We demonstrate enhanced dye adsorption capacity of nanoclay by decoration with chromium‐based MOF (MIL‐101) nanostructure. The Clay/Cr‐MOF composite exhibits a crystalline structure with high thermal stability. Moreover, it shows the superior specific surface area (4959 m2/g) and porosity which is beneficial for wastewater treatment. The developed Clay‐MOF composite exhibits superb adsorption capacity toward various organic dyes as compared with existing materials. The adsorption experiments revealed high adsorption capacity and selective dye removal efficiency of MOF‐modified nanoclay with reusability for multiple regeneration cycles. The adsorption kinetics was found to obey the pseudo‐second‐order kinetic model. These findings provide new insights into the application of such porous adsorbents for wastewater treatment applications.

“…[91][92][93] Environmental remediation is crucial for cleaning our planet's harmful pollutants, and nanoclays have found predominant usage in this area. [94][95][96][97] Research has advanced from the deployment of nanoclay as fillers 33,35,98 to self-propelled nanorobots 99 for the remediation of contaminants. The shearthinning properties of nanoclays upon fusion with both natural/synthetic polymers renders them ideal for both 3D and 4D printing.…”

“…[16] There are lot more previous research works, which explicated the importance of nanoclay addition into the polymer and its outcomes. [17][18][19][20] There have been several articles discussing silane-treated fibers and fillers' involvement in the polymer matrix medium. However, while research on nanoclay-toughened epoxy composites based on sisal, flax, jute, and coir fibers has been completed in great detail, only a partial examination of the combination of ramie fiber with organically-modified montmorillonite (OMMT) nanoclay has been conducted.…”

In this present study, the effect of silane treated ramie fiber addition along with organically-modified montmorillonite (OMMT) nano clay in epoxy resin composite was investigated in drop load impact, shear loading, and high-speed drilling. The main aim of this research study was to develop a high-laminar shear strength epoxy structural composite for various engineering applications. To improve the laminar adhesion the fiber was treated using silane via acid hydrolysis technique. The OMMT nanoclay also added with fiber in order to improve the load bearing effect and adhesion phenomenon. The composites were prepared using hand layup method with postcuring. The adhesion behavior of composites was tested based on American society for testing and materials standards and compared. According to the results, the treated ramie fiber possesses high resistance to impact loading. The ballistic resistance of composite is increased three fold when compare with as-received fiber-epoxy composites. The interlaminar shear strength of composite designation C 1.5 gives highest shear strength of 35 MPa. The drilling study revealed highest dimensional stability for treated fiber. No fiber chip off and pull out at the drilled hole surface. The fractography analysis confirms no lamina delamination occurs even at high-speed drilling. These delamination resistance epoxy-based composites are suitable in automobile, structural and defense gadget manufacturing applications.
