The design of intrinsically robust stretchable semiconducting polymers was achieved through OTBS‐mediated post‐functionalization of PDPP2T side chains with UPy units, generating dual hydrogen‐bonding motifs comprising weaker urethane linkages and strong quadruple UPy interactions along the long alkyl side chain, which is crucial for achieving desirable

A polymerizable deep eutectic solvent is reinforced with tannic acid‐modified cellulose nanofibers to construct a hierarchical dynamic eutectogel network. Synergistic covalent and reversible interactions impart ultrahigh stretchability, high ionic conductivity, broad temperature tolerance, self‐healing, and strong adhesion, enabling robust wearable ...

"Synthesis and properties of poly(butylene succinate) based copolymers and multi-block copolymers"
Polybutylene succinate (PBS) and a series of multi-block hydroxyl-terminated diol copolymers were synthesized by a "one-step"method with succinic anhydride (SAA) and 1,4-butanediol (BDO) as monomers, and terminal hydroxy diols as copolymer monomer.

Surface‐initiated photoiniferter‐mediated polymerization (SI‐PIMP) enables the controlled growth of UHMW polymer brushes with multi‐micrometer thicknesses, bridging conventional brushes and bulk‐like coatings. UHMW brushes are synthesized through a controlled/living process; they provide low friction and enhanced wear resistance under aqueous ...

Interaction‐Driven Assembly Pathways in Heterogeneous Active Microrobotic Systems
Peanut‐ and cube‐shaped light‐powered microrobots exhibit distinct magnetic and photocatalytic responses that determine their heterogeneous self‐assembly. In the dark, magnetic dipole interactions drive colloidal copolymerization with cubes acting as nucleation centers, whereas under light irradiation, phoretic interactions compete with magnetic ...
