Hollow silica nanoparticles (HSNPs) are consisted of silica shell and inner cavity. The HSNPs have a lot ofadvantages; low density, low thermal conductivity, material contain property, etc. As the eco-friendly synthesis method forHSNPs, there is the polyacrylic acid / ammonium (PAA/NH4OH) emulsion method. However, the method is required longerreaction time (> 14 hours), and the obtained HSNPs are polydispersed. Therefore, in this study, the effect of the catalyst for sol-gel reaction, molecular weight of PAA, and PAA concentration were investigated for synthesizing the uniformed HSNPs at theshorter reaction time. The 20 nm HSNPs could be synthesized at short time using the high molecular weight of PAA solution orlow PAA concentration solution.
