The core-shell polyacrylate latex particles containing fluorine and silicon in the shell were successfully synthesized by a seed emulsion polymerization, using methyl methacrylate (MMA) and butyl acrylate (BA) as main monomers, dodecafluoroheptyl methacrylate (DFMA), and c-(methacryloxy) propyltrimethoxy silane (KH-570) as functional monomers. The influence of the amount of fluorine and silicon monomers on the emulsion polymerization process and the surface properties of the latex films were discussed, and the surface free energy of latex films were estimated using two different theoretical models. The emulsion and its films were characterized by particle size distribution (PSD) analysis, transmission electron microscopy (TEM), Fourier transform infrared spectrum (FTIR), nuclear magnetic resonance ( 1 H-NMR and 19 F-NMR) spectrometry, contact angle (CA) and X-ray photoelectron spectroscopy (XPS), differential scanning calorimetry (DSC), and thermogravimetry (TG) analysis. The results indicate that the average particle size of the latex particles is about 160 nm and the PSD is narrow, the synthesized latex particles exist with core-shell structure, and a gradient distribution of fluorine and silicon exist in the latex films. In addition, both the hydrophobicity and thermal stability of the latex films are greatly improved because of the enrichment of fluorine and silicon at the filmair interface, and the surface free energy is as low as 15.4 mN/m, which is comparable to that of polytetrafluoroethylene (PTFE).

“…The water contact angle of hybrid film could reach 105.4°, when the amount of fluorinated monomer and SiO 2 is 15 and 2 wt%, respectively. In addition, fluorinated polyacrylate/silica hybrid latex was prepared using multistage emulsion polymerization in the presence of nano-silica particles by Qu [111,112]. The influences of fluoride (DFMA) and alkoxysilane (c-methacryloxypropyltriisopropoxidesilane, MAPTIPS) on latex morphologies and film roughness were investigated.…”

Polyacrylate latexes present good film-forming property, and therefore are used in a wide range of applications including coatings, adhesives, additives for paper, textiles, wood, and leather. However, some drawbacks, such as poor elasticity and low hardness have restricted their applications. This review summarizes recent development of polyacrylate latexes modified by polyurethane, organic fluorine, and inorganic nanoparticles, separately, which most often exhibit superior properties to those of their individual components. For each modification method, a comment is given based on our knowledge and related research experience. At last, some perspectives on the future research and development of modification of polyacrylate latexes are concluded.

Abstract.A superhydrophobic coating with excellent water repellence and gamma irradiation resistance was obtained by multi-walled carbon nanotubes (MWCNTs) modification. The effects of MWCNTs on the mechanical behaviour, water contact angle (WCA) and self-cleaning properties of the coatings were investigated. After 1.23×10 7 rad dose of gamma irradiation, WCA of the coating without MWCNTs modification (EPPM0) decreases from 150º to 140º and the adhesion reduces from 5B to 4B, respectively. While the coating (EPPM3) with 3wt% MWCNTs modification remains high WCA (152º ), excellent adhesion (5B) and hardness (6H). The results of dust removal test suggest that the coating still maintains self-cleaning property after high dose gamma irradiation.
