Adhesion characteristics of asphalt-aggregate interfaces based on surface energy theory

open access: yesZhongwai Gonglu
Based on surface energy theory, the sessile drop contact angle testing method was employed to measure the contact angles of five asphalt types (emulsified asphalt, water-activated asphalt, polyurethane asphalt, PG 76 modified asphalt, and 70# base ...

Alternative castor oil-based polyurethane adhesive used in the production of plywood

open access: yesMaterials Research, 2004
Plywood is normally produced with urea-formaldehyde and/or phenol-formaldehyde adhesives. However, the former is considerably toxic and environmentally damaging, while the latter is expensive, thus motivating the search for alternative raw materials in ...

Composites of Shellac and Silver Nanowires as Flexible, Biobased, and Corrosion‐Resistant Transparent Conductive Electrodes

open access: yesAdvanced Functional Materials, EarlyView.
Shellac, a centuries‐old natural resin, is reimagined as a green material for flexible electronics. When combined with silver nanowires, shellac films deliver transparency, conductivity, and stability against humidity. These results position shellac as a sustainable alternative to synthetic polymers for transparent conductors in next‐generation ...
