摘要: Composite particles are successfully fabricated in a shape of bead-on-bead through heterocoagulation. Submicron poly(styrene-co-acrylic acid) (PSAA) spheres prepared and used as guest materials composite particles. The adsorb on the gold surface host material perfect monolayered form pH dependence adsorption degree is also investigated. At strong acidic condition, effectively adsorbed materials, while efficiency dramatically decreases with increasing due to deprotonation carboxyl groups at spheres. Even though immersed good solvents PSAA for 12 h, exhibit excellent stability.
