Convenient Synthesis of Fluorinated Latexes and Core−Shell Structures by Miniemulsion Polymerization

Abstract

Fluorinated latexes in the size range of 100-250 nm are made by the polymerization of miniemulsions of fluoroalkyl acrylates as fluorinated monomers under employment of rather low doses of protonated surfactants. In addition, it is shown that miniemulsifaction of mixed monomer species allows efficient copolymerization reactions to be performed with standard hydrophobic and hydrophilic monomers in a joint heterophase situation, resulting either in core-shell latexes or in statistical copolymers. Contrary to the pure fluorinated polymers, those copolymers dissolve in organic solvents but still show the profitable interface properties of the fluorinated species.

A Facile Route to Synthesize Highly Uniform Nanocapsules: Use of Amphiphilic Poly(acrylic acid)‐block‐polystyrene RAFT Agents to Interfacially Confine Miniemulsion Polymerization

“…[6][7][8][9][10] In such a technique, the monomer solution of core material is dispersed into minidroplets with a diameter of 50-500 nm suspended in the water. [6] The minidroplets are kinetically stabilized by surfactant and co-stabilizer.…”

Facile synthesis of superhydrophobic TiO2/polystyrene core-shell microspheres

“…Recently, organic/inorganic composites have been received great interest due to their unique properties and possibility for numerous applications in modern technology [1][2][3], such as electroplating [4], biotechnology [5] and electrochemistry [6]. The core-shell sphere is one of the most attractive composite structure because of its amazing functions originating from the different composition of the core and shell materials.…”

Synthesis and characterization of fluorine-containing poly-styrene-acrylate latex with core–shell structure using a reactive surfactant

“…One strategy to solve this problem is to prepare the fluorine-containing polyacrylate (PA) or poly-styrene-acrylate (PSA) latex particles with a core-shell structure consisting of a fluorine-free core and a fluorine-containing shell and fixing the fluorine in the shell. [9][10][11][12][13][14] In this way, the excellent properties of PA (or PSA) and fluorinated materials can be preserved while the cost of fluorinecontaining materials is decreased considerably. On the other hand, in emulsion polymerization or miniemulsion polymerization, the residual emulsifier in the latex will bring negative effects to the properties of the products.…”
