A microwave heating process with a high heating rate and uniform heating was used to promote the silver reduction reaction. Silver nitrate (AgNO3) was used as the precursor of AgNPLs, and N,N-dimethylformamide (DMF) played the role of a solvent and reducing agent. Poly(vinylpyrrolidone) (PVP) with a molecular weight of 29,000 and a PVP/AgNO3 ratio of 10 were used to control the shape of synthesized AgNPLs. By adjusting the optimal microwave heating parameters, temperature ramping rate, reaction time, and reaction temperature, triangular AgNPLs with high aspect ratios could be produced. The synthesized AgNPLs had an edge length up to 700 nm and a thickness of 35 nm with aspect ratios up to 20. The AgNPLs were also used to produce conductive patterns via pen writing with a conductivity of 2 x 10(6) S/m to demonstrate the feasibility of applying the synthesized nanomaterials for electronic applications. 收起
