Aiming at the limitation of fabric color characterization with a single data source, multi-source data feature fusion method was used to characterize fabric color information. The correlation coefficient and the error of BP neural network color matching model are used for quantitative analysis. The results show that for cotton and polyester fabrics, the correlation coefficients of multi-data source fusion features are greater than 0.9, which is higher than that of single data source, and the characterization ability is stronger. At the same time, this method can significantly reduce the model error and improve the precision. The average error is less than 0.03, and the accuracy of the model is improved by more than 9% compared with the input of a single data source, which proves the effectiveness and universality of the proposed method.

Polymer nanocomposites generally exhibit unexpected dielectric/electrical performance far beyond the sum of every component, which is mainly due to the interface effect induced by the differences in structures and properties between the nanofillers and the polymer matrix. However, understanding the capricious interface effect in different polymer nanocomposites remains a major challenge. Here, we perform density functional theory calculations to investigate the atomic/molecular configurations and local charge behaviors of heterogeneous interfaces between the fillers of perovskites, oxides, two-dimensional materials, and polar/nonpolar polymers. Our findings demonstrate that atomic reconfiguration takes place during the formation of the inorganic/organic interface in order to minimize the overall energy of the system. Significant charge accumulation occurs at heterogeneous interfaces due to electron redistribution, especially for the examples of HfO2 and negatively charged Ca2Nb3O10. When applying an electric field, local polarization, especially around the interface, will be distorted and enhanced as a result of interfacial interaction. Even for the nonpolar polymer with linear dielectric oxides such as TiO2, induced dipole moments also appear near the interface, leading to the improvement of overall polarizability. The outcomes of our study verify that the variable electrical behaviors at the interfaces are highly dependent on the feature of every component constituting the inorganic/organic interface, which offers valuable insights for optimizing the experimental design of heterogeneous interfaces in polymer nanocomposites.

Bioinspired nacre-like CFRP composites with 3D organic mortar networks for synergistic multiscale toughness and impact resistance

Overcoming the conflict between strength and toughness is critical for structural materials. Carbon fiber reinforced polymer (CFRP) composites suffer from delamination and fiber breakage upon impacts due to the lack of toughness. Current strategies to improve the fracture resistance of composites mainly focus on interlaminar modification, which may lead to a decrease in strength and stiffness. Inspired by the "brick and mortar" structure in nacre, CFRP with a combination of high stiffness, strength, and toughness through ingenious structural design was developed in the current work. The bioinspired CFRP is composed of continuous carbon fiber layers (bricks) and composite paper layers (mortar) formed by aramid chopped fibers and polyphenylene sulfide (ACFs/PPS) 3D networks. The energy absorption and fracture toughness can be increased by 190.60 % and 165.78 % while retaining the stiffness. Multiscale toughening mechanisms were observed: crack deflection, interlayer slip, and plastic deformation of the 3D organic fiber network at the macroscale;progressive damage of ACFs at the micro- and nanoscale. Therefore, a rare combination of stiffness, strength, and toughness was realized, which also has excellent impact resistance. This 3D organic mortar network design provides a new avenue for fabricating strong, tough, and safe composites for defense, aerospace, and transportation engineering applications. © 2025 Elsevier Ltd

Temperature variation is a key factor in clothing design. It is important to monitor the temperature variations of human skin and clothing in real time under different exercise levels. Herein, using an innovative wearable monitor, the variations of skin temperature and clothing temperature during exercise under different conditions were explored. It was proven that the clothing temperature variation trend was almost the same as the human skin temperature variation, but relatively extreme conditions would lead to different temperature variations on human skin and clothing during exercise. The temperature difference between neighboring clothing layers was greater than that between the upper and bottom sides of a single layer. In addition, the temperature difference between adjacent layers of clothing varied from different clothing types. The results and experimental apparatus provided will provide the research basis for the development of comfortable sportswear.

An outstanding challenge for micro-optical systems is to achieve high resolution under wide-field-of-view (FOV) imaging. We propose a compact solution for high-resolution imaging under a wide-FOV with wavelength-scale thickness achromatic microlens arrays. Our strategy involves using aspherical sublenses to reduce spherical and chromatic aberration, as well as using small-diameter achromatic microlenses to decrease incident ray height. With the aid of computational reconstruction, the array of microlenses can achieve a wide-FOV comparable to that of commercially available lenses with equivalent large diameters. The microlens array shows a significant advantage in imaging resolution and an order smaller thickness compared to commercial lenses. This highly integrated microlens array, characterizing high-resolution imaging under a wide-FOV, will play an important role in applications such as autonomous driving, endoscopy, virtual reality, and augmented reality.
