“…However, some inferior properties of waterborne polyurethanes, such as low mechanical strength and water resistance, have limited its available application range, and hence, problems related to their properties and processing can largely be resolved by proper molecular designs and hybridization with other materials [2][3][4][5][6][7].…”

To study the dispersity of different amine-graphene oxide (amine-GO) in polymer matrix and the interfacial interactions between functionalized graphene oxide and matrix, two kinds of modifiers-organoamine-and aminosilane-coupling agents-were used to functionalize graphene nanosheets to obtain functionalized graphene oxide/waterborne polyurethane nanocomposites by in situ polymerization. The chemical structure, morphology, and interlayer space of amine-GO nanoplatelets were confirmed by FT-IR, Raman, TGA, XPS, TEM, AFM, and XRD. The dispersity behaviors between different amineGOs and polymers were evaluated by FESEM. The thermal, mechanical, and hydrophobic properties of the nanocomposites were investigated by TGA, tensile testing machine, and water contact angle test, respectively. It was found that the tensile strength of nanocomposites was increased from 10.13 to 27.79 and 28.96 Mpa after the addition of amine-GO functionalized by APTMS and APTES, respectively. The better thermal stability and hydrophobicity of nanocomposites were also achieved by the addition of amine-GO, especially those modified by aminosilane-coupling agents. This study paves a new route for designing and developing chemically converted graphene oxide nanosheets/polymer nanocomposite materials by altering suitable amine-modifier to functionalize graphene oxide nanosheets and then optimizing the interphases between graphene oxide nanosheets and polymer matrices.

“…The alkyd resin was synthesized from soya fatty acid, phthalic anhydride, benzoic acid and pentaerythritol. The insertion of anhydride moieties within the acrylic prepolymer ensured the efficient coupling between the acrylic prepolymer and the alkyd resin and prevented the phase separation [25] .…”

SbstractFour waterborne hyperbranched alkyd-acrylic resins (HBRAA) were synthesized by miniemulsion polymerization from a hyperbranched alkyd resin (HBR), methyl methacrylate (MMA), butyl acrylate (BA) and acrylic acid (AA), by using benzoyl peroxide (BPO) and ammonium persulfate (AP) as initiators. The reaction between HBR and acrylic monomers was evidenced by differential scanning calorimetric (DSC), nuclear magnetic resonance (NMR) and gel permeation chromatography (GPC). The conversion percentage, glass transition temperature (T g ), content of acrylic polymer (determined by soxhlet extraction) and molecular weight increased with the content of acrylic monomers used in the synthesis. The main structure formed during the synthesis was the HBRAA. The analysis by dynamic light scattering (DLS) showed that the particle size distribution of HBRAA2, HBRAA3 and HBRAA4 resins were mainly monomodal. The film properties (gloss, flexibility, adhesion and drying time) of the HBRAA were good.

“…In this study, we carry out a mixture design in the surroundings of a specific composition of the hybrid dispersion retained on the basis of our previous study [12,13]. The composition of the hybrid dispersion was varied in a four-component system with constraints and results were analyzed using a mathematically independent variable approach [16,17].…”

“…The chemical hybridization of acrylic and alkyd structures is expected to provide the advantages of acrylic polymers such as hardness, gloss, weatherability and chemical resistance, and also the advantages of alkyds such as good adhesion, high gloss and good penetration. Furthermore, given the low glass transition of the alkyde backbone, there is no need to add the coalescing solvent in order to ensure good film formation [12]. In our previous work, self-emulsifying hybrid acrylic-alkyd waterborne dispersions, exempt of any added solvent or surfactant were synthesized by melt condensation reactions between oil-modified acrylic pre-polymers and medium-oil alkyd resins, followed by an emulsification through the neutralization of the carboxylic groups by a base [13].…”
