Sulphur-prevulcanised skim (SPVS) rubber particles were heterocoagulated on an aggregate of a disinfectant agent (chlorhexidine digluconate; CHD)-poly(methyl acrylate) (PMA) nanocapsules. The CHD-PMA nanocapsule stabilized by lecithin was prepared using the modified nanoprecipitation of PMA from an organic continuous phase onto nanodroplet containing the CHD aqueous solution. Cationic and anionic nanocapsules were produced by separately redispersing the nanocapsules into a water and 0.5% sodium dodecyl sulphate (SDS) aqueous solution, respectively. The largest aggregate, which was obtained from homocoagulation of the CHD-PMA nanocapsules with opposite charges, was selected as a core surrounded with SPVS shell particles. An interpolymer complex between poly(ethylene oxide) (PEO) moieties adsorbed on the aggregate and indigenous surfactant (protein-lipid) and/or SDS on the SPVS particle surface was the driving force for heterocoagulation. Data from the size, zeta potential measurements and TEM images of the heterocoagulated CHD-PMA/SPVS indicated the composite particle containing the CHD-PMA core.
