Cobalt nickel bimetallic oxides (NiCo2O4) have received numerous attentions in terms of their controllable morphology, high temperature, corrosion resistance and strong electromagnetic wave (EMW) absorption capability. However, broadening the bandwidth is still a huge challenge for NiCo2O4-based absorbers. Herein, unique NiCo2O4@C core-shell microcubes with hollow structures were fabricated via facile sacrificial template strategy. The concentration oxygen vacancies morphologies three-dimensional (3D) cubic framework effectively optimized by adjusting calcination temperature. specially designed 3D structure facilitated multiple reflections incident waves provided rich interfaces between components, generating significant interfacial polarization losses. Dipole polarizations induced could further enhance attenuation ability EM waves. exhibit superior EMW capability minimum RL (RLmin) -84.45 dB at 8.4 GHz thickness 3.0 mm. Moreover, ultrabroad effective (EAB) as large 12.48 (5.52-18 GHz) obtained. This work believed to illuminate path synthesis high-performance cobalt absorbers excellent capability, especially bandwidth.

Compatibilizing and toughening blends of recycled acrylonitrile-butadiene-styrene/recycled high impact polystyrene blends via styrene-butadiene-glycidyl methacrylate terpolymer

Polymer, Journal Year: 2023, Volume and Issue: 272, P. 125856 - 125856

Published: March 7, 2023

To increase the effectiveness of recovered acrylonitrile-butadiene-styrene (rABS) and recycled high impact polystyrene (rHIPS), styrene-butadiene-glycidyl methacrylate (SBG) was incorporated to rABS/rHIPS system by melt blending for first time. Multiple epoxy groups in SBG can combine with butadiene ageing generate ester groups, repairing broken molecular chains, improving compatibility between two phases, enhancing mechanical properties blends. The findings demonstrated that adding greatly increased blends' weight, strength, tensile flexural storage modulus, loss complex viscosity. When content 8 wt%, notch strength blends reached 8.84 kJ/m2, which 108% higher than rABS/rHIPS. In addition, interface polybutadiene (PB) phase styrene-acrylonitrile copolymer (SAN) became more blurred, phases improved, enabled high-value recovery
