ConspectusSelf-healing ability is one of the most attractive features biological tissues, as it helps living creatures to recover physiological functions and prolongs their lifespans after unexpected injuries. Inspired by this feature, self-healing artificial polymers have been developed based on extrinsic intrinsic designs since 1950s. In particular, received enormous attention 2001 because unlimited times easy preparation. Therefore, many excellent works are reported, our understanding...

Natural rubber (NR) material is indispensable in various fields of our daily life, while its preparation usually involves toxic cross-linking agents and energy-consuming vulcanization processes. The permanent network NR products also makes degradation recycling difficult. Herein, a fully biosourced, vulcanization-free developed by simply introducing carrageenan (KC) the matrix via facile aqueous mixing method. nonrubber components (NRCs) on latex particles are crucial importance for this art...

Exploring novel healing mechanisms is a constant impetus for the development of self-healing materials. Herein, we find that side-chain interlocking bottlebrush polymers can form dynamic network and thereby serve as driving force process Molecular dynamics simulation indicates formed by interpenetration between long side chains adjacent molecules stabilized van der Waals interactions molecular entanglements chains.

3D printing in a microgel-based supporting bath enables the construction of complex structures with soft and watery biomaterials but low print resolution is usually an obstacle to its practical application tissue engineering. Herein, high-resolution collagen organ scaffold realized by using engineered Gellan gum (GG) microgel containing trisodium citrate (TSC). The introduction TSC into system not only mitigates aggregation GG microgels, leading more homogeneous morphology also suppresses...

In this paper, graphene oxide (GO) and carbon nanotube (CNT) hybrid fillers were used to replace partial black (CB), GO/CNT/CB/NR composites prepared with excellent crack growth resistance, low heat build-up superior mechanical properties. Mechanical testing revealed a significant synergistic reinforcement between GO/CNT CB in NR composites. The improved dispersion of the matrix was characterized by transmission electron microscopy (TEM). Through fatigue test, showed resistance compared...

Graphene has exceptionally high surface area, mechanical properties, electrical conductivity, thermal and gas-barrier performance, thus it is considered as an ideal multifunctional filler for rubbers. However, harnessing these properties in rubber nanocomposites requires us to carefully tailor the dispersion state of graphene, vulcanization kinetics, interfacial interaction so on. This review summarized our recent works on how disperse graphene homogeneously matrix, what influence or oxide...

Despite the widespread application of prevulcanized natural rubber latex film (VNRL), its microstructure VNRL has not been fully elucidated, and impact on strain-induced crystallization (SIC) mechanical properties remains largely unexplored. Herein, hierarchical was unraveled, results were compared with those a vulcanized sheet (VNR) prepared by mixing compression molding. With identical total cross-linking density, exhibits more homogeneous network higher entanglement content than VNR. Upon...

Styrene–butadiene rubber (SBR), a widely employed synthetic elastomer, has found diverse applications, including transportation, sealing, and conveyor belts. Nevertheless, the conventional covalent cross-linking network inherently restricts its recyclability reprocessability, leading to substantial resource depletion considerable environmental degradation.

Embedded extrusion printing provides a versatile platform for fabricating complex hydrogel-based biological structures with living cells. However, the time-consuming process and rigorous storage conditions of current support baths hinder their commercial application.

Notably, ionic modification, PVA...

Embedded extrusion printing facilitates the fabrication of complex biological structures using soft hydrogels that are challenging to construct conventional manufacturing methods. While this targeting strategy is appealing, residues support materials on printed objects have been overlooked.
