Abstract: We developed nano-sized blackberry-likenanoparticles consisted polypyrrole (PPy) nano bumps on the spherical silicananoparticle core. The black berry-like bumpy nanoparticles can eliminate thecoffee-ring effect when their dispersion and form submicron scale uniformsurface, meanwhile quasi-amorphous structure were formed and showedangle-independent color and PPy bumps produced uniform light absorber toenhance the color contract. We also showed the broad capability of bumpynanoparticles ink for handwriting, painting and the microscale stacking.
