Given the strong temperature dependence of thermal initiators, spatial temperature variations significantly affect both local monomer reactivity and the macroscopic evolution of polymer structures. Understanding this coupling is crucial for designing gradient-controlled synthesis strategies. The dissipative particle dynamics (DPD) method was employed to investigate free radical polymerization under gradient temperature conditions. Increasing Δ<i>T</i> enhances spatial heterogeneity: high-temperature regions form dense networks with lower molecular weights (<i>M</i><sub>n</sub> and <i>M</i><sub>w</sub>) due to rapid initiation and frequent termination. In contrast, low-temperature regions yield higher molecular weights and expanded chain conformations (&lt;<i>R</i><span>\u0000 <sup>2</sup><sub>g</sub>\u0000 \u0000 </span>&gt;) resulting from longer radical lifetimes. These structural differences further govern pore evolution: porosity decreases rapidly and reaches lower final values in high-temperature zones, while low-temperature regions exhibit delayed evolution but higher final porosity.

Conventional fabrication strategies for polymer MNs mainly rely on mold-assisted vacuum casting or hot pressing.

Herein, we report a vacuum-assisted pressing strategy for MN fabrication based on <i>O</i>-carboxymethyl chitosan (CMCA) and natural polyphenol protocatechuic acid (PCA) supramolecular composite slurries. This method enables MN production under significantly reduced processing times (&lt;12 h) and mild thermal conditions (50 °C).

The resulting polymer-polyphenol supramolecular composites exhibit robust mechanical properties, with a fracture stress of 0.5 MPa and a toughness of 1.31 MJ·m<sup>−3</sup>. Notably, supramolecular MNs demonstrated a high fracture force of up to 1.08 N per needle, indicating sufficient mechanical integrity for transdermal insertion.

Herein, we developed four selenium-fused NIR-absorbing acceptors (Y-SeNF, Y-SeNF-2ClO, Y-SeBNF, and Y-SeBNF-2ClO) by regulating the molecular photoelectric properties <i>via</i> end-group and side-chain dual-engineering.

Structural analysis confirmed the guest incorporation and borate network formation. Guest loading decreased the visible transmittance, whereas borate crosslinking partially restored the transparency and improved the thermal integrity (main decomposition near 430 °C). The films exhibit good mechanical performance (for PVA-A: 32.70 MPa tensile strength; 245.60 MPa modulus; and 63.82 MJ·m<sup>−3</sup> toughness), while crosslinking/coordination increases stiffness (up to 1479.55 MPa modulus for PVA-A-TA).

First, a mold enabling region-selective silver plating was fabricated through model design and 3D printing technology. Second, PU foam was placed inside the mold to create controllable exposure regions. Third, a region-selective silver plating process was achieved by exploiting this localized exposure, thereby successfully constructing conductive grating composite foams (grating-Ag/PDA@PU). The effects of the grating number, arrangement pattern, spacing, and incident angle of electromagnetic waves on the electromagnetic interference shielding effectiveness (EMI SE) were systematically investigated, revealing the structure-property relationship between shielding performance and grating geometric parameters. The results indicate that the EMI SE values of a single-layer conductive grating are positively correlated with the number of gratings. For a multilayer conductive grating, staggered parallel arrangements exhibit superior shielding performance compared to simple parallel arrangements. Appropriately increasing the spacing between gratings helps reduce mutual electromagnetic coupling, thereby enhancing the overall EMI SE values. It was also found that a nondestructive electromagnetic shielding switch could be realized simply by flipping the sample. Specifically, the EMI SE values changing from 3.53 dB to 34.04 dB can be achieved by simply flipping the foams.

The DSCFT simulations reveal that the linear sequence of slow-relaxing “hard” and fast-relaxing “soft” blocks encodes two programmable kinetic motifs: a hard-soft-hard sequence drives a sharp, droplet-coalescence-triggered conversion from loop to bridge conformations during viscoelasticity-mediated phase inversion, whereas a soft-hard-soft sequence governs a gradual, network-contraction-driven relaxation of chain conformations. Serving as modular kinetic codes identified in the system of triblock copolymers, these kinetic motifs were shown to operate concurrently within tetrablock chains and generalize to penta- and hexa-block architectures, demonstrating the scalability and robustness of sequence-encoded dynamics.
