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 ...

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 ...

Polymers are composed of very large molecules formed by a combination of different monomers (smaller and simpler molecules), which can be natural or synthetic. Polymers are the basis of many ...

(b) Linear polymers in which the intermolecular forces of attraction are in between those of elastomers and fibres and can be melted again and again on heating followed by moulding to give the desired ...
