Use of nonionic ethylene oxide surfactants as phase-transfer catalysts for poly(acrylic acid) adsoroxylated surfactants enables poly(acrylic acid) (PAA) to adsorb to negatively charged silica surfaces despite its unfavorable electrostatic interaction with the surface. In the absence of surfactant, PAA does not adsorb to silica to any extent that is measurable by our methods. We used optical refle作者: progestogen 時間: 2025-3-22 22:31
