Elucidating the Friction Catalytic Lubrication Mechanism of Ag Nanoparticles Loaded on MOFs

Advanced Materials Interfaces, Volume 12, Issue 17, September 8, 2025.
A novel Ag@Co‐BDC nanocomposite lubricating additive is successfully synthesized, which effectively promoted interfacial tribochemical reactions to form a protective tribofilm during friction, resulting in a 16.7% reduction in friction coefficient and a 61.5% decrease in wear rate for base oil.

Selective Functionalization of MWCNTs: Enhancing Wear Mechanisms and Friction‐Induced Graphitization in Epoxy Composites

Macromolecular Materials and Engineering, Volume 310, Issue 9, September 2025.
Incorporating 0.3 wt.% COOH‐functionalized MWCNTs, well dispersed via ultrasonication, into epoxy significantly enhances tribological and mechanical performance, reducing wear by 82% and COF by 32%. During sliding, friction breaks down MWCNTs into graphitic fragments, which are slowly released, forming a protective tribofilm.

An Adaptive Artificial Neural Network Model for Predicting Friction and Wear in Polymer Matrix Composites: Integrating Kragelsky and Archard Laws

Macromolecular Materials and Engineering, Volume 310, Issue 9, September 2025.
This study presents a hybrid modeling approach that integrates an artificial neural network (ANN) with Kragelsky’s and Archard’s laws to predict the coefficient of friction (COF) and wear rate in epoxy composites. It emphasizes the superior predictive accuracy for graphite over MoS₂, highlighting the need to consider environmental sensitivity when ...
