The wearing comfort of fabrics is strongly related to moisture permeability and thermal insulation. To enhance comfort, the localized surface plasmon resonance (LSPR) effect is applied on cotton fabrics by densely packed hybrid nanogels containing gold nanoparticles on the surface. The nanogels are prepared by emulsion polymerization using di(ethylene glycol) methyl ether methacrylate (MEO 2 MA), (ethylene glycol) methyl ether methacrylate (OEGMA 300 ), and ethylene glycol methacrylate (EGMA) as monomers. Because of the different transition temperatures of MEO 2 MA (25 °C) and OEGMA 300 (60 °C), the obtained nanogels present a linear shrinkage behavior between 20 to 50 °C. Further treated with in situ reduction, gold nanoparticles (Au NPs) are embedded in the nanogels. After cross-linking the hybrid nanogels onto cotton fabrics and exposure to visible light irradiation (0.1029 W), the ratio of moisture permeability of the cotton fabrics cross-linked with hybrid nanogels (weight gain ratio, WGR of 8%) at 30 °C to that at 20 °C is 1.67. It is 45% better than that of cross-linked pure nanogels without any Au NPs. When the WGR is increased to 15%, the ratio is up to 2.18, thereby almost doubling that of the cross-linked pure nanogels. Such improvement is caused by the LSPR effect from the densely packed hybrid nanogels on the cotton fabric, which induces a more efficient photothermal conversion and prominent shrinkage of the hybrid nanogels. In addition, because the Au NPs can well absorb light irradiation, the cotton fabrics cross-linked with hybrid nanogels are able to efficiently shield the incident light and present a good capability of heat insulation. Therefore, the obtained cotton fabrics can adjust their comfort according to the external light conditions, well suited for outdoor scenarios such as running and hiking.

Fluorescent hydrogel as an advanced material has been used for anti‐counterfeiting, probe detection, and optical devices. A facile strategy to prepare fluorescent hydrogel was developed by carboxymethyl cellulose (CMC) with Europium(III) and polyvinyl alcohol (PVA). The hydrogel formed a physical cross‐linking network under mild reaction conditions without using volatile organic chemicals. The addition of CMC‐Eu(III) improved the mechanical properties of the hydrogel. At 15% CMC‐Eu(III), the hydrogel reached its maximum tensile and compressive stress, which were 47.25±10.35 kPa and 10.14±1.90 kPa, respectively. Meanwhile, the hydrogels exhibited a 5D0→7F2 characteristic emission peak assigned to Eu3+, which emitted stable red fluorescence under 254 nm UV light. When this hydrogel was applied to paper, the paper shows hidden fluorescent dots under UV light. This additive also enhances the mechanical properties of the paper, which reveals the multifunctionality of this fluorescent hydrogel for anti‐counterfeiting and reinforcement.This article is protected by copyright.
