Self-reinforced aluminum phosphate framework/bismaleimide composites with double cross-linking hybrid structures

Abstract

In this work, aluminum phosphate framework (APF)/ bismaleimide (BMI) hybrid composites with the double cross-linking hybrid (DCH) structures are successfully fabricated in right conditions. Herein, the three-dimensional (3D) structures of APF play the critical role in the reinforced effects of mechanical properties. Aim to strengthen the APF/BMI composites, the lamellar aluminum phosphate (LAP) particles are chosen by self-reinforced effects. From the perspective formation of the LAP-APF complex, the structures of the LAP-APF/BMI composites are investigated and the mechanical and dielectric properties are evaluated. Finally, the reinforced mechanism is also analyzed. The maximum flexural strength can approximately reach up to 170.46 MPa, and the dielectric constant further decreased after the addition of LAP particles. There are helpful for designing the higher performance inorganic/organic hybrid composites and expanding their applications.
