Patent published on the 2026-06-04 in WO under Ref WO2026115909 by ALPS ALPINE CO LTD [JP] (Sato Shunetsu [jp])

Abstract: A resistor substrate production method according to the present invention comprises: a coating step for coating an ink that contains a solvent, a thermosetting resin, and conductive particles onto a substrate and forming a conductive coating film; a drying step for drying a workpiece, which is obtained by providing the conductive coating film on the substrate, at a second temperature that is lower than a first temperature at which a curing reaction of the thermosetting resin progresses, and remo[...]


Our summary: The method involves coating a substrate with an ink containing a solvent, thermosetting resin, and conductive particles to form a conductive film. It includes drying the workpiece at a lower temperature, followed by hot pressing to partially cure the resin. Finally, the workpiece is fired to complete the curing process, resulting in a resistor substrate with enhanced wear resistance.

Transmission of EM Waves Passing Through a Multilayer Structure

Published on 2026-01-28 by Vanja Mandri?, Slavko Rup?i?, Bogdan Pavkovi?, Ismail Baxhaku @MDPI

Abstract: This article investigates the behavior of an electromagnetic field passing through a composite material&amp;mdash;a multilayered structure. The material consists of a dielectric material polymethyl methacrylate (acrylic, plexiglass) to which one or more layers of conductive paint are applied to attenuate the field strength. This field attenuation is possible precisely because of the chemical structure of the paint, which contains carbon-based particles and is therefore very successful in its[...]


Our summary: This article examines the transmission of electromagnetic waves through a multilayer structure. It focuses on the effect of conductive paint layers on field strength attenuation. Simulations and measurements confirm the effectiveness of the composite material in reducing the electromagnetic field.

Multiscale Synergistic Investigation on the Mechanical and Tribological Performances of Graphene-Reinforced PEEK/PTFE Composites

Published on 2026-01-23 by Yan Wang, Kaiqi Dong, Henan Tang, Bin Yang, Shijie Wang @MDPI

Abstract: Polytetrafluoroethylene (PTFE) is a self-lubricating material but has poor wear resistance. The wear resistance of the composites was enhanced by the incorporation of polyetheretherketone (PEEK), whereas the friction-reducing performance was compromised, thus resulting in an inherent trade-off between wear resistance and lubricity. Graphene nanosheets (GNSs) with high strength and lubricity were introduced as a reinforcement for PEEK/PTFE composites. Composite specimens with varying GNS contents[...]


Our summary: The study investigates the mechanical and tribological properties of graphene-reinforced PEEK/PTFE composites. Incorporating graphene nanosheets enhances wear resistance while maintaining lubricity. Molecular dynamics simulations reveal the mechanisms behind improved performance and optimal graphene content.
