Synergistic Effect of Functionalized Nanokaolin Decorated MWCNTs on the Performance of Cellulose Acetate (CA) Membranes Spectacular

Abstract

In order to enhance salt rejection level and high pressure mechanical integrity, functionalized nanokaolin decorated multiwall carbon nanotubes (FNKM, 0–5 wt % loading) were incorporated into a cellulose acetate (CA) matrix using high temperature solution mixing methodology. Scanning electron microscopy (SEM), X-ray diffraction technique (XRD), thermo-gravimetric analyzer (TGA) and Fourier transform infrared spectrometer (FTIR) were used to characterize the prepared membranes. The obtained results revealed that with increasing FNKM concentration in the host polymeric matrix, composite membrane’s structural, functional, thermal, water permeation/flux and salt rejection characteristics were also modified accordingly. Percent enhancement in salt rejection was increased around threefold by adding 5 wt % FNKM in CA.

“…It also generates a self-healing characteristics within the membranes that eventually cause reduced pore size. 20 The addition of the activated filler also decreases the polymer chain scission phenomenon that occurs due to the water evaporation. The surface texture of the prepared membranes elaborates that with the increase in the loading concentration of functionalized nanoferrites the porous structure can be controlled.…”

“…Also reference crystallinity of nanoferrites and Kevlar is higher as compared to CA that eventually suppresses the CA peaks comparatively. 20…”

“…To make it happen with ease and affordability at low cost, some unusual water purification techniques should be adopted. 19,20 Polymeric membranes are thought as a best choice for desalination and/or chemical separation processes. The catching motivation is their developed ways of utilization in the respective fields.…”

“…Since CA is well known for its biocompatible nature. 10,20 But along with all well-known characteristics features CA membranes their mechanical strength is a question. To address this issue and utilize the aforementioned membranes at higher applied pressures Kevlar fabric support have been added.…”
