Nanosilica modified with polyaspartic acid as an industrial circulating water scale inhibitor

Abstract Given the special performance of nanosilica with its small size, large specific surface area and high surface activity, nanosilica containing reactive amino group (denoted as SiO2–NH2) and polysuccinimide were allowed to take part in polymerization reaction to afford SiO2–NH2 modified polya...
