“…Based on the XPS spectrum, the intensity of the signal coming from fluorine (F1s) was higher in the film-air interface than in film-glass interface. Migration of fluorinecontaining groups from the copolymer structure to the filmair interface results from a decrease in the free energy in the surface of the latex film [45]. Examples of XPS spectra demonstrating the surface composition and deconvoluted C1s profile are presented in the Fig.…”

“…The morphology of particles composed of a polystyrene core with a shell of polyacrylate containing fluorine was successfully determined by depositing of a diluted particle suspension on a carbon-coated copper grid, staining it with 1.0 wt% phosphotungstic acid (PTA) for 3 min and drying it [45]. The use of phosphotungstic acid also allowed for successful determination of the structure of particles composed of a poly(methyl methacrylate) core and a hydrophilic shell made of biopolymers or polymers containing amine groups, such as casein, gelatin, chitosan, branched poly(ethylene imine), poly(allylamine) [66] or poly(vinylamine) [67].…”

The design and synthesis of various polymer coreshell particles result from their distinct characteristics, which combine the properties of two or more components into one material. Many accessible synthetic strategies for obtaining polymer core-shell particles lead to the formation of particles for which the internal morphology differs from the ideal coreshell structure. Understanding the precise morphology characteristics is important for mechanistic studies of particle formation, which ultimately results in the design of particles for specific structures and properties. The detailed characteristics of complex polymer particle structures are complicated and require more than one method. This review focuses on imaging methods such as transmission electron microscopy (TEM), cryo-TEM, scanning transmission electron microscopy (STEM) and confocal fluorescence microscopy that reveal the radial redistribution of the components and methods for the quantitative analysis of individual phases (core, shell and interfacial layer), such as small-angle X-ray scattering (SAXS), small-angle neutron scattering (SANS), differential scanning calorimetry (DSC) and nuclear magnetic resonance (NMR). Methods that can determine the surface composition and makeup of the character of interfacial layer (gradient or containing small domains, etc.) were also reviewed.

“…The polymerizable emulsifier could be chemically bonded to the PUs to avoid long‐term leaching, and it is therefore more environmentally friendly than conventional emulsifiers. In addition, since the PU emulsion was dispersed in water via self‐emulsification, the preparation of fluorinated polyurethane–acrylate (FPUA) emulsions could be considered as a soap‐free emulsion polymerization . Transmission electron microscopy (TEM) was used to observe the morphology of PU and FPUA emulsions, and the results showed that fluorine could aggregate onto the surface of FPUA particles during the formation of the core–shell structure.…”

Fluorinated polyurethane-acrylate (FPUA) hybrid emulsion was prepared by copolymerization of polyurethane, methyl methacrylate, and 1H,1H,2H,2H-heptadecafluorooctyl acrylate (FA) via emulsion polymerization in the presence of a perfluoronated reactive surfactant. The polyurethane was synthesized from isophorone diisocyanate, poly(propylene glycol)-1000, dimethylolpropionic acid, 1,4-butanediol, and 2-hydroxyethyl methylacrylate. The influence of the monomer on the surface properties, wetting behaviors, particle size, and viscosity of the emulsion was investigated. The mechanical properties of FPUA latex films were improved, and water absorption and contact angle were improved with the addition of methyl methacrylate and FA. V C 2016 Wiley Periodicals, Inc. J.

“…In recent years, the development of soap-free emulsion polymerization [8,9] and reactive surfactants [10][11][12] has promoted the substantial improvement of the resistance to water of the polyacrylate latex films. In order to improve the adhesion properties of polyacrylate emulsions, the tackifying resins especially rosin resin and its derivatives have attracted more and more attentions.…”

Hydrogenated rosin/polyacrylate composite miniemulsions-based pressure sensitive adhesives were synthesized by in situ miniemulsion polymerization method. The effect of HR amount on the monomer conversion rate, particle size and its polydispersity, coagulum rate, Zeta potential, and stability of the composite miniemulsions were studied, the effect of HR and crosslinker amount on the adhesion properties of the composite latex films were also investigated, and the composites were characterized by differential scanning calorimetry (DSC) and gel permeation chromatograph. The results showed that with HR amount increasing, the monomer conversion rate decreased, and the absolute value of Zeta potential and the molecular weight of the sol in the composite latex films also decreased, while the particle size and its polydispersity were almost unaffected. DSC analysis indicated that HR had relative good compatibility with polyacrylate. However, excess HR amount led to the decrease of the centrifugal stability and storage stability of the composite miniemulsions. Furthermore, with HR amount increasing, the ball tack of the latex films increased gradually, 180 o peel strength first increased and then decreased, and holding force decreased constantly. When HR amount exceeded 10 wt%, the failure style changed from interface failure to cohesion failure. The crosslinker CX-100 was helpful for the improvement of 180 o peel strength and holding force. When HR and CX-100 amount were 10 and 0.6 wt%, the ball tack, 180 o peel strength, and holding force were 9 #, 8.9 N/25 mm, and 178 h, respectively.
