“…Although the strength of LEID-3 is lower than that of CM-3, it is still significantly larger than those of commonly used engineering plastics (Fig. 3d), such as Nylon 6 (110.0 MPa), polysulfone (107.0 MPa), and acrylonitrile butadiene styrene copolymer (ABS, 76 MPa) 44,[49][50][51] . Therefore, our LEID with high mechanical strength and can be used as the structural material.…”

Load bearing/energy storage integrated devices (LEIDs) allow using structural parts to store energy, and thus become a promising solution to boost the overall energy density of mobile energy storage systems, such as electric cars and drones. Herein, with a new high-strength solid electrolyte, we prepare a practical high-performance load-bearing/energy storage integrated electrochemical capacitors with excellent mechanical strength (flexural modulus: 18.1 GPa, flexural strength: 160.0 MPa) and high energy storage ability (specific capacitance: 32.4 mF cm−2, energy density: 0.13 Wh m−2, maximum power density: 1.3 W m−2). We design and compare two basic types of multilayered structures for LEID, which significantly enhance the practical bearing ability and working flexibility of the device. Besides, we also demonstrate the excellent processability of the LEID, by forming them into curved shapes, and secondarily machining and assembling them into complex structures without affecting their energy storage ability.

“…At the same time, LCHBPs could improve the surface energy of PLA by the hydrophilic segments, thereby improving the wettability of PLA and CA, which was conducive to the improvement of the PLA / CA compatibility. 56 Therefore, LCHBPs could improve the compatibility of the PLA/CA blends as a highly-efficiency compatibilizer.…”

A type of long‐chain hyperbranched polymers (LCHBPs) was prepared by grafting hydroxyl‐terminated flexible long chain onto hyperbranched polymers (HBPs). The structure of LCHBPs was confirmed by Fourier transform infrared (FT‐IR) and nuclear magnetic resonance (1H‐NMR) analysis. It was then used as the modifier for toughening and compatibilizing the polylactic acid (PLA)/cellulose acetate (CA) blends. Upon the addition of LCHBPs, the compatibility between PLA and CA was improved, the dispersion of CA particles in PLA matrix was more uniform, and the brittle‐ductile tear transition of the PLA/CA blends was occurred. The crystallization of PLA was promoted by the addition of LCHBPs. By adding LCHBPs, glass transition temperature and cold crystallization temperature were reduced, the crystallizability was enhanced, and the crystallization temperature range was expanded. The thermal decomposition temperature of the PLA/CA was found increased with the addition of LCHBPs. When the content of LCHBPs was 1 phr, the elongation at break and the tear strength of the PLA/CA blends were increased by 484% and 38.24%, respectively. Meanwhile, the thermal stability and hydrophilic properties of the blend films were improved by adding LCHBPs.

“…20,21 However, mounting concerns surrounding the release of volatile organic chemicals (VOCs), coupled with anxieties about the depletion of petroleum reserves and the unpredictable fluctuations in petroleum feedstock prices, have prompted innovative exploration across diverse chemical industries. [22][23][24] In response, the use of bio-based alternative reagents and biobased polymers to enhance the interface between CF and the resin matrix is increasingly garnering attention within the academic and research communities, [25][26][27][28][29] mainly due to their abundant availability, cost-effectiveness, and environmental sustainability. [30][31][32] Consequently, a great deal of research has been dedicated to the development of bio-based WPUs synthesized using green solvents, with the aim of serving a wide spectrum of applications.…”
