Summary: Bis(triethoxysilyl)ethane (BTESE) nanoparticles were incorporated into aromatic polyamide (PA) membranes via in-situ polymerization to prepare BTESE nanocomposite PA (BTESE-TFN) membranes for reverse osmosis. The BTESE nanoparticles increased surface roughness, hydrophilicity, and changed the structure of the PA membranes, leading to improved salt rejection and water flux. Modification of organic bridged groups in the BTESE showed great potential to further enhance the water flux and durability of the BTESE-TFN membranes.

Summary: Understanding the kinetics of interfacial polymerization (IP) reaction is crucial for tailoring the characteristics and performance of reverse osmosis (RO) membranes. In this study, the kinetic behavior and film characteristics of polyamide (PA) film formation by IP reaction between M-phenylenediamine (MPD) and trimesoyl chloride (TMC) were investigated using the absorbance spectroscopy (AS) method in real-time. The results showed that monomer concentration and reaction time significantly influenced the kinetics of the IP reaction. The study confirmed the potential of the AS method for predicting the characteristics and optimizing the conditions of IP to achieve customized RO and nanofiltration (NF) membranes.

Summary: This study investigated the influence of fiber dissolution on the properties and structure of Single-polymer composites (SPCs) by adjusting polymerization time with varying activator dosage. It was found that the highest activator dosage led to maximum tensile strength, while a lower dosage resulted in longer polymerization time, destruction of oriented chain structure, and formation of oligomers, resulting in low strength and high deformation in SPCs. To achieve a good reinforcing effect, creating a sufficiently large dissolution window by reducing polymerization time is necessary.

Summary: In-situ synthesized Cu2S nanoparticles were used to improve the tribological performance of PAI lubricating coatings. The results showed that in-situ synthesized Cu2S nanoparticles more effectively promoted the tribological performance compared to hydrothermal synthesized Cu2S nanoparticles. This was attributed to the interfacial interactions between in-situ synthesized Cu2S nanoparticles and PAI during the curing process, leading to enhanced dispersion performance and bonding strength. In addition, a continuous organic-inorganic composite tribo-film formed on the counterpart steel ball surface, restraining direct abrasion and significantly promoting the tribological performance of the coatings.
