- •
A facile preparation method for HGPAs by using HG and PPy as assembling primitives.
- •
The HGPAs show hierarchical porous network with PPy uniformly embedded in aerogel.
- •
The superior supercapacitor performance of HGPAs benefits from the unique structure.
- •
The effect of PPy nanoparticle sizes on electrochemical properties is investigated.
