Abstract
Adsorptions of anionic surfactant (Sodium dodecyl sulphate, SDS), cationic surfactant (Hexa-decyltrimethylammonium bromide, CTAB) and non-ionic surfactant (octylphenolpoly (oxyethylene),
TritonX-100) on natural rubber (NR) latex particles were studied. The adsorption isotherms of these
surfactants on NR particles were constructed. It was found that CTAB adsorbed more on NR compared with
SDS and TritonX-100 adsorption because CTAB molecules can adsorbed on NR surface by electrostatic
interactions and hydrophobic interaction. The adsorption of CTAB on NR particles can be enhanced when NR
particles was preadsorbed with SDS because the bilayer of CTAB could be formed via tail-to-tail hydrophobic
interaction on top of adsorbed-SDS.
