Abstract
- As epoxy resin (EP) is widely used in the microelectronic field, it is essential to improve its electromagnetic wave (EMW) absorption and flame retardancy simultaneously. In this work, we synthesized a novel nanohybrid, RMN (Fe 3 O 4 /NHS@M(OH)(OCH 3)@rGO (M = Co, Ni)), with petal-shaped anisotropic interfaces, by using graphene oxide as the core and the 2D nanosheets M(OH)(OCH 3) (M = Co, Ni) as the petal, with nickel hydroxystannate and ferrite as further modifications. The RMN combines carbon-based materials, ferrites and conductors, and represents the petal-like structure with rich nondirectional interfaces. The results show that EP composite containing 25 wt% RMN represented excellent EMW absorption, with a minimum reflection loss of −55.79 dB (with 7.4 mm thickness at 3.1 GHz). Moreover, the EP composite with 15 wt% RMN (EP/RMN700-3) had the lowest peak heat release rate of 470.9 kW m−2, which was 69.7 % lower than pure EP, showing a significantly improving in flame retardant. The thermal conductivity efficiency of EP/RMN700-3 increased to 128.4 % compared with the pure EP, which effectively reduces fire risk caused by heat accumulation. This study provides a valuable solution to overcome the challenges of EMW absorption and flame retardant for EP in the microelectronic materials field. [Display omitted] • The nonoriented petal-like structure provides rich interface. • Carbon materials, ferrites and conductors support the multiple absorbing mechanisms. • EMW absorption, flame retardant and thermal management suit for electronic packaging.
