Macromolecules make up the majority of plastics, which are then processed into shaped pieces, semi-finished goods, films, or fibers. The selection of macromolecules, the production method, and the ...

Professor Xiaokong Liu's team at Jilin University proposed an "activation-quenching" strategy for dynamic covalent chemistry, achieving precise and controllable "on-off" switching of dynamic bond ...

Composites of continuous carbon fibers and thermoset polymers can now be made using a new 3D printing technology. Such composites are strong and lightweight and may find applications in many ...

A team of scientists has got a step closer to making several different types of plastic much easier to recycle, using a method that could be applied to a whole range of difficult-to-recycle polymers, ...

WDue to their good mechanical properties and low production costs, natural fibres are becoming a feasible choice as reinforcement for polymer matrices. Their low density also affords very good ...

What do airplanes, bridges, and wind turbines have in common? They can all be made from lightweight, strong, composite materials made of polymers reinforced with strong carbon fibers. Fiber-reinforced ...

Naturally, the importance of high performance and cost-effectiveness cannot be overstated when designing structural components for aerospace, marine, civil, automotive, and other such industries.

Polymers with breakable bonds inserted into the polymer chains (B) were more easily degraded and re-formed than those with breakable bonds in the cross-lnks (A). A team of UK scientists has got a step ...
