The study of synthetic organic polymers rapidly expanded since Staudinger's recognition of
the covalent structure of macromolecules. Today, these materials are far from just an …

As a kind of polymeric material with high flexibility and durability, polyurethanes (PUs) are
widely used in industry, electronic products, construction, transportation and medical fields …

While transesterification has been largely explored by chemists, only a few studies
comparatively dealt with its “sluggish cousin”, transcarbamoylation. Originally suggested 70 …

High-performance lignin-containing polyurethane elastomers (LPUes) were successfully
synthesized via partially substituting petroleum-derived polyols with depolymerized …

A Schiff base containing dual-dynamic covalent bonds synthesized from the biomaterials,
cystine and vanillin, showed excellent reversibility under external stimuli by metatheses. The …

In this work, tough and fast light-controlled healable lignin-containing polyurethane
elastomers (LPUes) with a dynamic dual-crosslinking network were successfully …

Durable electromagnetic interference (EMI) shielding is highly desired, as electromagnetic
pollution is a great concern for electronics' stable performance and human health. Although …

The reprocessing or recycling of cross-linked polymers by incorporating dynamic covalent
cross-links has the potential to increase their usable lifetimes and reduce their …

Combining autonomous self-healing and reprocessing in one material offers an extended
life span and enables shape configuration changes. We developed commodity poly ((2 …

Polyurethane (PU) has not only been widely used in the daily lives, but also extensively
explored as an important class of the essential polymers for various applications. In recent …
