چکیده
Investigation of particle nucleation in surfactant-free emulsion polymerization styrene using Laponite clay as Pickering stabilizer is considered. The effective number platelets contributing to the surface charge polymer particles calculated, and used estimate their stabilizing efficiency. A coagulative mechanism proposed coagulation coefficient calculated Derjaguin–Landau–Verwey–Overbeek theory. Hamaker constant involved attractive potential clay-polymer composite measured experimentally. model found fit experimental data terms nucleated period. higher than allowing full latex coverage at end nucleation. Moreover, efficient stabilization against requires almost complete coverage.

Pickering emulsion templated interfacial atom transfer radical polymerization for microencapsulation.
This Article describes a new microencapsulation method based on a Pickering emulsion templated interfacial atom transfer radical polymerization (PETI-ATRP). Cationic LUDOX CL nanoparticles were coated electrostatically with an anionic polymeric ATRP initiator, poly(sodium styrene sulfonate-co-2-(2-bromoisobutyryloxy)ethyl methacrylate) (PSB), prepared by radical copolymerization of sodium styre...
متن کاملPickering Emulsion Polymerization of Styrene-co-butyl Acrylate Nanoparticles by Using Cloisite Na+ as Surfactant
Cloisite Na+was used as a solid surfactant (stabilizer) in Pickering emulsion polymerization of styrene-co-butyl acrylate in presence of oil soluble initiator, azobisisobutyronitrile (AIBN) and water soluble initiator, potassium persulfate (KPS). Fourier transform infrared (FTIR) spectrum approved the corporation of Cloisite Na+ layers within the polymer matrix. Effect of clay content was a...
متن کاملMaterial : Aging mechanism in model Pickering emulsion
The chemicals used for the NPs synthesis are TetraEthylOrthoSilicate (TEOS), l-Arginine, chloride acid 0.1M and ethanol. They were supplied by Aldrich and used as received. High-purity deionized water (18.2 M.cm) was produced using Millipore Milli-Q Gradient system. The synthesis follows the same protocol as in our previous work [1]. It is performed in a 2000 ml reactor thermostated with hot wa...
