The giant reduction of the barrier properties due to self-healing microcapsules and lack real-time protection during healing remained main challenges in anticorrosion coatings. Herein, a facile strategy using Janus graphene oxide (GO) as dense flexible shell has been proposed synergistically solve these challenges. Benzotriazole (BTA) was used synthesize GO at oil-water interface, GO/BTA/poly(methyl methacrylate) were prepared. Energy-dispersive X-ray spectroscopy, Fourier infrared Raman ultraviolet spectrophotometer analysis confirmed formation structure with one surface hydrophilic other hydrophobic. morphology J-GO-capsules high coverage rate observed by scanning electron microscopy. biobased content coating containing showed low-frequency impedance value above 10

Efficient Preparation of Core–Shell Particles via Photopolymerization for Toughening Photocurable Resins

Langmuir, Год журнала: 2025, Номер unknown

Опубликована: Фев. 11, 2025

Core–shell particles have been widely used in improving the toughness of resin, but a convenient and efficient large-scale preparation method for core–shell is lacking currently. In this work, an simple has developed to fabricate by combining photopolymerization phase separation inside emulsion droplet. strategy, two photocurable prepolymers with different hydrophilicity were dissolved cosolvent dispersed aqueous solution form emulsion. Upon removal cosolvent, occurred The hydrophilic prepolymer migrated toward oil–water interface converted shell under UV irradiation, while hydrophobic interior droplet core. addition, ratio size particle could be easily adjusted, which provided idea particle. influence structure contents on toughening effect was investigated. Under optimal parameters (the 1:1, 1 μm, concentration 7.5 wt %), toughness, impact strength, flexural fracture (KIC) composites enhanced 52, 8.4, 30.8, 288.4% compared pure resin system, respectively. Furthermore, Tg value viscosity system not greatly influenced after addition particles, i.e., outstanding achieved without sacrificing its thermal property processability.

Overview on Comparison of Four Preparation Methods and Physical Properties of Graphene

Nanomaterials and Nanotechnology, Год журнала: 2025, Номер 2025(1)

Опубликована: Янв. 1, 2025

Graphene is a single layer of carbon atoms arranged in hexagonal lattice structure, forming two‐dimensional (2D) material with exceptional mechanical, electrical, and thermal properties. has emerged as one the most promising nanomaterials because its unique combination properties: thinnest strongest materials, an excellent conductor electricity, optically transparent well. This article provides overview graphene materials regarding basic preparation methods, The four commonly used methods for preparing are compared, advantages disadvantages each expounded briefly summarized. And physical properties obtained by method, namely, mechanics, thermal, optics, were elaborated detail, related applications prospects further discussed.
