摘要

This study developed a strategy for preparing high-performance aluminum/graphene oxide (Al/GO) composites through the interface modification mechanism of phase-transitioned bovine serum albumin (PTB) and process optimization. Initially, the reduction of disulfide bonds in bovine serum albumin (BSA) using tris(2-carboxyethyl) phosphine (TCEP) triggered a conformational transition from α-helical structures to β-folded arrangements, yielding PTB oligomers with amyloid-like aggregation properties. The PTB modification strategy markedly enhanced interfacial characteristics of Al/GO composites through dual mechanisms: (1) PTB improved Al/GO compatibility via optimized surface wettability, (2) PTB forms a powerful adhesive layer through self-aggregation, significantly enhancing the adhesion between GO and Al, enabling GO to be uniformly dispersed in the Al matrix. Systematic investigations further correlated Al particle size (1-100 μm) and GO lateral dimensions with interfacial characteristics. A composite material tablet pressing with uniform GO distribution was produced by cold isostatic pressing at 10 kN for 20 seconds. Subsequently, high-performance Al/GO composites were prepared by melt casting. The experimental results show that its hardness and thermal conductivity have been enhanced by more than 40% compared with pure Al, and its corrosion resistance has also been significantly improved. This work demonstrates the crucial role of PTB in addressing the incompatibility of the Al/GO interface and provides an expandable approach for multifunctional metal matrix composites.
