Composites based on PVA and Al–Zn structures with excellent mechanical properties

Abstract

Films of polyvinyl alcohol (PVA) with Al–Zn fillers were prepared using underwater pulsed plasma. Electrodes made of these materials were used as a source of Al and Zn structures. During the action of the plasma, the electrodes were sprayed. α‐Al2O3, ZnO, and Zn–Al layered double hydroxides were formed. X‐ray and Fourier transform infrared spectroscopy (FTIR) analyzes of the composites obtained showed a strong interaction between the polymer and fillers. The mechanical properties of the films showed that the incorporation of aluminum and zinc structures into the polymer matrix under the action of plasma leads to a giant increase in the mechanical strength of PVA at a filler concentration of 0.5%–3%. The electrical characteristics of polymer composites showed the non‐linear behavior of J–Vcurves. The results obtained show one of the new range of applications of pulsed underwater plasma in the production of reinforced polymer composites.

Development of highly conductive hybrid Ni‐biocarbon‐based polyvinyl alcohol composites for microwave shielding properties

“…However, further inclusion of Ni‐biocarbon hybrid particles shows increment for 1 vol% of particles while it shows decrement for further raised in vol% which is 3 and 5 vol%. This decrement is because of the particles amalgamation in matrix which makes composite brittle which clearly observed in fractography illustrates in Figure 5D,E [ 28,29 ] by addition of is 3 and 5 vol% of hybrid particles for composite designation N21 and N31. And the raised in properties is due to addition of this 1 vol% of hybrid particles reduces the voids and improves bonding for composite designation N11.…”

Intercalation of silsesquioxane surfactant in layered double hydroxide for silicone rubber composites: Enhancing interfacial interactions toward improvement of mechanical, thermal, and gas barrier properties

“…The interfacial adhesion between the filler and matrix significantly impacts the mechanical properties of materials 44 . The five‐cycle loading‐unloading tests of the SR composites are presented in Figure 6A – D. The tensile moduli of the SR/Ca‐Mg‐Al LDH, SR/LDH‐SQ‐20, SR/LDH‐SQ‐40, and SR/LDH‐SQ‐60 composites at 300% elongation (ε 300% ) during initial loading were 2.19, 2.21, 2.39, and 2.58 MPa, respectively.…”
