Abstract
This article is dedicated to synthesis of aqueous solutions of nanoparticles based on rosin. Dependence of colloidal stability of rosin nanoparticles (RNP) on different factors (such as pH, solvent nature, and temperature) were investigated and discussed. Obtained RNP samples were characterized by dynamic light scattering, UV-visible absorbance spectroscopy, and scanning electron microscopy. It was found that RNP usually have size in the range 100‒200 nm with a maximal stability at neutral pH which is caused by relatively high surface charge of RNP (‒40 mV). Acidic media leads to fast precipitation of RNP, while alkali one leads to complete dissolution of the RNP due to formation of abietates (abietic acid is the main component of rosin).
