Abstract
Polymers are ideally utilized as damping materials due to the high internal friction of molecular chains, enabling effective suppression of vibrations and noises in various fields. Current strategies rely on broadening the glass transition region or introducing additional relaxation components to enhance the energy dissipation capacity of polymeric damping materials. However, it remains a significant challenge to achieve high damping efficiency through structural control while maintaining dynamic characteristics. In this work, we propose a new strategy to develop hyperbranched vitrimers (HBVs) containing dense pendant chains and loose dynamic crosslinked networks. A novel yet weak dynamic transesterification between the carboxyl and boronic acid ester was confirmed and used to prepare HBVs based on poly (hexyl methacrylate-2-(4-ethenylphenyl)-5,5-dimethyl-1,3,2-dioxaborinane) P(HMA-co-ViCL) copolymers. TheA B n ${{AB}_{n}}$ -type of macromonomers, the crosslinking points formed by the dynamic covalent connection via the associative exchange, and the weak yet dynamic exchange reaction are the three keys to developing high-performance HBV damping materials. We found that P(HMA-co-ViCL) 20k-40-60 HBV exhibited ultrahigh energy-dissipation performance over a broad frequency and temperature range, attributed to the synergistic effect of dense pendant chains and weak dynamic covalent crosslinks. This unique design concept will provide a general approach to developing advanced damping materials.

Abstract
Energy dissipation, a ubiquitous process in biological systems, has been intensively studied and widely used to guide the transient assembly of natural or synthetic molecules, but very few examples of material transient healability controlled by this important process have been reported. Herein, we realize the healing of creep-resistant and kinetically inert polymer hydrogels that is driven by the respiration of baker's yeast (Saccharomyces cerevisiae) and spontaneous energy dissipation. The entire healing process can be simply controlled by a single variable: sucrose concentration. Due to the high activity and stability of yeast in the hydrogels, multiple local healing events become possible and healing of damaged hydrogels is also efficient after a long waiting time. All these results indicate that our yeast-containing polymer hydrogels are kinetically stable materials, which can be readily healable on demand.

Abstract
The conventional synthesis of methacryloyl hyaluronic acid (HA-MA) requires an extremely high amount of modification reagents, the organic solvents, and strenuous purification steps. Herein, a new green synthetic approach for the methacryloyl hyaluronic acid preparation with a tailorable substitution degree (SD) is reported, in which methacryloyl hydrazide is used as a more reactive reagent and only water is used as the solvent. The new method significantly reduces the amount of functionalization reagents (as low as only 0.3 equiv) and avoids the use of any organic solvents. The substitution degree can be tailored from 26% to 86% in a facile controllable manner. The new HA-MA (termed as HA-MA-H) can be UV-cross-linked to form a biocompatible hydrogel.

Abstract
Dynamic stability and self-healing ability are two inherently compatible properties for living organisms. By contrast, kinetic stability and intrinsic healability are two desired but mostly incompatible properties for synthetic materials. This is because the healing of these materials heavily relies on the kinetic lability of the chemical bonds or physical interactions in materials. Inspired by the hierarchically and temporally controlled wound healing in biological systems, here, we report the intrinsic healing of kinetically stable hydrogels, regulated by the consumption of chemical nutrients. The acylhydrazone-based polymer hydrogels with preinstalled urease and urea were formed at a low initial pH, followed by in situ enzymatic generation of a base to deactivate the dynamic bonds, allowing efficient fabrication of kinetically stable hydrogels. The healing of damaged hydrogels was effective when fed with proper chemical nutrients (i.e., acidic urea solutions), in which case a transient acidic pH state was temporally programmed by combining a fast acidic activator (for structural healing) with the slow, biocatalytic generation of a base (for property recovery). The ability to regulate both hydrogel fabrication and healing via a single enzymatic reaction could provide a new approach to create kinetically stable materials capable of healing damages on demand.
