Patterned anti-reflective (AR) film using hollow silica nanoparticles (HSNPs) was achieved by inkjet printing technology. Various refractive indices for optimizing AR coating on different substrates were controlled by tuning the void space and wall thickness of HSNPs. Highly enhanced mechanical resistance could also obtained by combining HSNPs and its binder.
