This work illustrates a "soft-toughness" coupling design method to integrate the shear stiffening gel (SSG), natural leather, and nonwoven fabrics (NWF) for preparing leather/MXene/SSG/NWF (LMSN) composite with high anti-impact protecting, piezoresistive sensing, electromagnetic interference (EMI) shielding, human thermal management performance. Owing porous fiber structure of MXene nanosheets can penetrate leather construct stable 3D conductive network; thus both LM LMSN composites exhibit...
High protection performance and intelligence are gradually becoming indispensable key factors with the ever-improving personal protective equipment. However, material that can not only resist but also percept full type of impacts is an urgent need due to complex combat scenarios. This work reports intelligent leather/shear stiffening gel (SSG)/Kevlar-shear thickening fluid (STF)/non-woven fabric (LSKSN) composite, which exhibits superior comprehensive impact resistance in needle puncture,...
With the combination of high flexibility and thermal property, thermally conductive elastomers have played an important role in daily life. However, traditional display limited stretchability toughness, seriously restricting their further development practical applications. Herein, a high-performance composite is fabricated by dispersing room-temperature liquid metal microdroplets (LM) into polyborosiloxane elastomer (PBSE). Due to unique solid-liquid coupling mechanism, LM can deform with...
Abstract The directional and dynamic hydrogen bonds are of vital importance for both nucleic acids proteins, but they naturally apply strong multiple in pendant groups weak single bond the backbone. hierarchy orthogonality biological systems inspire to elegantly tailor supramolecular polymeric materials robust mechanical properties. Herein, this work has fabricated ultrastrong tough through bioinspired rational design Based on quadruple ureidopyrimidinone amide, polymer with optimized...
With the development of intelligent protective wearable equipment, flexible materials with impact resistance have become a focus attention. Shear stiffening gel (SSG) is smart material that can perceive external force loads and generate mechanical responses, boasting exceptional properties like fast response, adaptability, self-healing. Since SSG absorb large amount energy during dynamic impact, it shows remarkable advantages for safety protection applications. During past decade, there has...
As a natural material, leather has been widely used in daily life due to its high biocompatibility, wearing comfort, and excellent mechanical strength. However, with the increasing demand for better among people, single function of difficulty meeting requirements, which limits application prospects. It is particularly important develop multifunctional composites diverse characteristics. Therefore, can be modified functionally designed through physical chemical methods towards intelligent...
This work develops the Leather/SSG composite with a laminated structure that consists of flexible leather and rate-dependent shear stiffening gel (SSG), which exhibits superior impact resistance shock wave protection performance. The SSG is tightly bound to fiber network through hydrogen bonding interactions between interfaces. Owing phase change energy absorption effect synergizing force dispersion along disordered fibers, can effectively alleviate (52%) shows high (0.86-0.95). Besides,...
Warmth preservation in cold climates requires a long-term heat supply. Conventional thermal devices usually deliver excessive and have difficulty preventing loss. Herein, to achieve durable comfort, an asymmetric composite (AAAC) is devised through vacuum-filtrating silver nanowires (AgNWs) onto the surface of poly(ethylene glycol) (PEG)-infiltrated aramid nanofiber aerogel. AgNW e-skin can transfer strong Joule back side AAAC, where infused PEG further stores energy by phase transition then...
Abstract Objective . In previous studies, the factors affecting accuracy of imaging photoplethysmography (iPPG) heart rate (HR) measurement have been focused on light intensity, facial reflection angle, and motion artifacts. However, factor specularly reflected has not studied in detail. We explored effect HR estimation proposed an method for direction radiated light. Approach To study influenced by light, we control component controlling its angle. A total 100 videos from four different...
