“…[ 6 ] Plasma surface treatment [ 7 ] has an action depth of only 50–100 nm, which will not cause significant damage to the material's structure. [ 8 ] Moreover, it has low energy and environmentally friendly, and has a visible effect. Therefore, plasma surface modification is critical for improving the interfacial bonding properties of fiber‐reinforced composites.…”

This study reveals the interfacial properties of multicomponent plasma with four aspects, including cleaning, etching, functionalization, and polymerization. Particles formed by plasma ionization collide to form volatile groups, which can interact with the surface to form volatile substances that clean the surface. The multicomponent plasma etching effect on the surface is significant, and O 2 and N 2 may interact to improve oxidation capacity. Inert gas argon (Ar) can be combined with reactive gases O 2 , N 2 , and NH 3 to introduce hydroxyl and amine groups and other active groups to change the surface's chemical structure. When a multicomponent plasma polymerizes, a film forms on the surface, changing the chemical composition. The cross-linking of gases has a positive effect on the properties of the deposited layer as well. The treatment of various fiber materials, nanoparticles, polymer films, and matrix materials with multicomponent plasma is summarized. The multicomponent plasma significantly improves surface wettability and roughness, and oxygen species aid in the etching of nanomaterials, which improves interface properties. The gas types determine the groups introduced to the surface and the surface attachment site.

“…However, some fibers have low surface energy and usually show poor surface wettability and affinity, 2 and the composites are easy to delaminate when bearing external force, which greatly reduces their service life. 3 The bond strength of the fiber-matrix interface can directly affect the ability of fiber to transfer and bear stress, 4 therefore, how to effectively improve the bonding strength between fiber and matrix is of great significance in related fields, 5,6 to improve the interface properties of the material surface, some surface treatment methods are adopted. 7 However, some modification methods will be limited by factors such as low mechanical performance, high instrument cost, poor industrialization, specific technology and so on.…”

This study reveals the characterization and mechanical properties of glass fiber warp knit structural fabric/vinyl ester resin composites treated by cold nitrogen glow discharge plasma. The effects of nitrogen plasma treating parameters (including power, flow rate, and time) on tensile and bending properties of glass fiber warp knit structural composites were investigated. It was shown that nitrogen plasma treatment enhanced the tensile and bending property of the glass fiber warp knit structural composites. SEM, FTIR and AFM characterized etching existing on the surface, C-N and N-H groups were introduced, and varying degrees of roughness. The response surface analysis represented that the nitrogen plasma treated glass fiber warp knit structural composites obtained optimized bending properties with the power ranging from 130 W to 160 W, the flow rate ranging from 8sccm to 9sccm, and the time ranging from 100s to 110s.

“…In recent years, novel nanocomposites that combine conductive polymers and magnetic materials have drawn strong research interests thanks to their potentials for microwave absorption. [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17] Conducting polymers can effectively shield electromagnetic waves generated from an electrical source, whereas electromagnetic waves from a magnetic source can be effectively shielded only by magnetic materials. The nanocomposite materials have a dual absorption mechanism of dielectric loss and magnetic loss, which broadens the microwave absorption band and enhances the microwave absorption efficiency.…”

Conductive polypyrrole (PPy) is an excellent polymer material for microwave absorption, which is vital for reducing electromagnetic interference (EMI) for electronic devices. To improve the microwave absorption capability and enhance the thermal stability and mechanical ductility of conductive PPy, metallic magnetic nanoparticles can be added to form PPy nanocomposites. In this paper, we present the first study to compute the electromagnetic properties of PPy nanocomposites based on the first principles method. It is discovered that (1) while doping can improve the microwave absorbing proper-ties of PPy material, the absorption performance does not necessarily increase with the number of doping position; (2) conductivity and absorption coefficient increase significantly for the PPy nanocomposite compared with PPy. The dielectric loss is more than 2 at about 2 eV; (3) reflectivity and absorption coefficient decrease with the increase of PPy content in PPy/Co nanocomposite; (4) the average magnetic moment of the PPy nanocomposite is the same as that of pure nanoparticles, and this indicates that only nanoparticles generate magnetic loss for the nanocomposite.
