Description
Sungyoung Yoon and Jongbok Lee tune a rubber tweak that lifts glue films in work dated 2025. The base stuff, HTPB, fills polyurethane binders and glues but grips poorly and ages fast. Adding oxygen rings to its chain, called epoxidation, can fix both faults. Past work used a high-cis form, while shop-grade stock is low-cis. The pair swept the dose of the oxidant used.
Dose alone set how far the tweak ran; heat and time barely mattered. Films peaked at ten percent tweak, with best strength, grip, and chemical guard. Water soak fell too. Past that point, gains ebbed as the web grew too tight.
