Fabrication and characterization of temperature and pH resistant thin film nanocomposite membranes embedded with halloysite nanotubes for dye rejection

The Role of Nanoparticle Shapes and Structures in Material Characterisation of Polyvinyl Alcohol (PVA) Bionanocomposite Films

“…At the low HNT content of 3 wt %, the smooth surfaces of PVA/HNT bionanocomposites can also be ascribed to the combination of strong interactions and good compatibility between HNTs and PVA matrices. Nonetheless, increasing the HNT content up to 5 and 10 wt % leads to much higher surface roughness (i.e., R q = 4.54 ± 0.18 and 13.1 ± 0.23 nm, respectively) due to the presence of prevalent HNT aggregates [38].…”

Inkjet printing of graphene oxide and dopamine on nanofiltration membranes for improved anti-fouling properties and chlorine resistance

“…Developing advanced TFC membranes for NF process has been an intensely researched topic over the last few decades due to their wide range of applications. Conventional TFC membranes are often fabricated by interfacial polymerization (IP) which forms a thin active layer on top of a microporous, thicker support substrates [1][2][3]. Properties of the active layer are is controlled by the IP process condition parameters including reaction time, temperature, monomer concentration, method to remove excess solution etc.…”

Thin Film Nanocomposite of Nanofiltration Membrane for Water Softening and Desalination

“…Many attempts have been carried out to improve the performance of TFC membrane. For example, incorporating nanofillers, such as silver nanoparticles (Ag NPs) [29], graphene oxide (GO) [30], carbon nanotube (CNT) [31], silica [32], titanate nanotube (TNT) [33] and halloysite nanotube (HNT) [34], either within PA layer or porous substrate. Upon the addition of nanofillers, the thin film membrane is normally referred to as TFN membrane Over the last 20 years, the NF study has shown sparks interest among the researchers in many different areas.…”
