“…Resin emulsion‐stabilized chemical surfactants are usually used as film former of sizing agent. However, because of the thermodynamic instability of general emulsifier, the stability of emulsion would easily be affected by the external factors such as temperature, pH value and occur the phenomenon of stratification or precipitation, etc . Meanwhile, surfactant molecules could move freely and tend to assemble on the surface of sizing agent film and form a hydrophilic layer.…”

The Graphene oxide (GO) sheets were used for preparing the epoxy resin Pickering emulsion. The particle size and the zeta potential of the Pickering emulsion were measured to evaluate its stability. The stable emulsion could be served as the film former of sizing agent for carbon fiber (CF). The effect of the Pickering emulsion stabilized by GO sheets on the properties of CF and the interfacial adhesion property of CF reinforced composite were investigated. Scanning electron microscopy (SEM) images showed that there existed a layer of sizing agent film with GO sheets evenly on the CF surface. Abrasion resistance and stiffness values of CF were tested and the results indicated that the sized CF conformed to the requirement of CF handleability. The interlaminar shear strength (ILSS) test indicated that the interfacial adhesion of the composite could be greatly improved. The fracture surfaces of CF composites were examined by SEM after ILSS tests. © 2015 Wiley Periodicals, Inc. J. Appl. Polym. Sci. 2015, 132, 42285.

“…With the initial size of WPU without silane incorporation of 32 nm, the size of A10 has reached 120 nm, while the size of A20 is about 148 nm. We suppose that the alkoxysilane groups in the side chains of WPU may have a chance to take part in the hydrolysis reaction and convert to hydrophilic silanol groups, which make a contribution to stabilizing the polymer colloidal particles and prevent them from coalescing at large scales . In all of the APD‐Si contents, AWPU with a homogeneous emulsion‐like appearance is observed, as displayed also in Figure .…”

Environmentally friendly waterborne polyurethanes (WPUs) modified by moisture‐curable alkoxysilane have been much studied nowadays. In this work, a new diol‐bearing pendant urea‐propyl trimethoxysilane (APD‐Si) was synthesized and used as the chain extender in the preparation of a silicone‐modified WPU dispersion. Both the formation of hybrid networks based on the condensation of trimethoxysilane groups and the enhanced microphase separation of the hard and soft segments have been found to rely on the strong hydrogen‐bonding capability of the urea‐containing spacers, which link the alkoxysilane groups with the backbone of WPU. Because of the synergism of chemically bonded silsesquioxane and physically hydrogen bonded hard domains serving as crosslinking points, the mechanical properties of the hybrid films of WPU are improved, especially the modulus and yield strength. © 2018 Wiley Periodicals, Inc.

“…However, when 1 or 21 g of silica was employed, the latices displayed strong shear-thinning behavior. Based on the stabi- lization mechanism presented in our previous work [20], we would believe that some hydrogen bonds between hydroxyl groups of the silica particles increased the viscosity of the latex. However, the hydrogen bonds were easily cleaved under mechanical stirring.…”
