A thin filament stimulated by Ca2+ to combine with myosin is the structural basis achieve sliding and muscle contraction. Though a large variety of artificial materials has been developed mimicking muscle, on-demand combination actin never precisely reproduced in polymeric systems. Herein, we show that both process combined structure have mimicked construct synergistic covalent supramolecular polymers (CSPs). Specifically, photoirradiation as stimulus induces independently formed (CPs) (SPs)...
Supramolecular polymer networks (SPNs) demonstrate great potential in the development of smart materials owing to their attractive dynamic properties. However, as they suffer from inherent weak bonding most noncovalent cross-links, it remains a significant challenge construct SPNs with outstanding mechanical performance. Herein, we exploit cryptand/paraquat host-guest recognition motifs cross-links prepare class highly strong and tough SPNs. Unlike those supramolecular relatively binding...
Abstract Crosslinking plays a crucial role in determining mechanical properties of polymer materials. Although various crosslinks based on covalent or noncovalent bonds have been adopted, it remains an enormous challenge to develop crosslink which could endow corresponding network with robust yet dynamic properties. Herein, we report simultaneously having property and woven geometry, the (WPN) integrate merits (CPN) supramolecular (SPN). In specific, WPN not only exhibits comparable...

Introducing dynamic covalent bonds can breathe life into polymers by endowing recyclability and tunability to materials, but the characteristic structure dynamics of associative exchange polymer networks are yet be understood. In this study, we present a model analyze intermediates kinetic process exchange. The relationship between reaction equilibrium constant plateau modulus is established. was validated vinylogous urethane vitrimers (BPOVU) with different stoichiometric ratios at various...
The ability to accurately predict the rheological behavior of blends two incompatible polymers is critical polymer industry. constitutive modeling requires understanding structure and dynamics across different length scales. polydispersity chain at molecular level nonuniformity flow field due dispersed domains mesoscopic present significant challenges this industrially relevant problem.

The viscosity and viscoelasticity of polyelectrolyte solutions with a single electrostatic interaction have been carefully studied experimentally theoretically. Despite some theoretical models describe experimental results well, the influence multiple interactions (electrostatic hydrophobic) on rheological scaling is not yet fully resolved. Herein, we systematically study microstructures properties short-side-chain perfluorosulfonic acid (S-PFSA), most promising candidate proton exchange...
Compared to the wall slip of polymer melts, less attention has been paid viscoelastic solids, such as crystallized polymer. The existence polymers not only prevents precise measurement their properties but also leads flow instabilities during processing like injection molding. In this work, a continuous cyclic strain sweep test is designed resolve behaviors polypropylene under large-amplitude oscillatory shear at different temperatures. A stick–slip transition identified, and its critical...
Fast deformation of entangled melts is known to cause chain stretching due affinelike straining the entanglement network. Since may also result in perturbations covalent bond angles and length, there are always possible enthalpic effects. In this study, we first subject polystyrene PMMA different molecular weights either uniaxial melt extension or planar subsequently impose rapid thermal quenching preserve deformation. Then, such pre-melt-deformed samples annealed at various temperatures...
Theoretical analysis was made for dielectric relaxation of model chains, linear Rouse chains having type-A dipoles and being end-adsorbed (tethered) desorbed at equilibrium, with an attempt to find a clue investigation the adsorbed chain dynamics in polymer nanocomposites. Expanding bond vector those respect eigenfunctions, we obtained analytical expressions normalized complex permittivity first-moment average time chains. The respectively, were found exhibit retarded accelerated due...
