Poly(acrylic acid) + zinc diacetate hybrid composites have been prepared by precipitation from aqueous solutions and drying. The lowest glass transition temperature Tg determined by differential scanning calorimetry (DSC) is 392°C, providing a service temperature range unusually large for polymer-based materials (PBMs). Thermogravimetric analysis (TGA) shows that thermal decomposition begins so...

Application of a delaminated kaolin clay base coat onto linerboard provides a barrier coating for a subsequently applied polymer top coat with potential advantages of increased paper stiffness, improved water resistance at reduced polymer overcoat. Motivated by coating material cost reduction, feasibility of the technique is demonstrated by applying a delaminated clay coating online followed by...

Waterborne coating has recently been paid much attention. However, it cannot be used widely due to its performance limitations. Under the specified conditions of the selected resin, selecting the function pigment is key to improving the anticorrosive properties of the coating. Zinc phosphate is an environmentally protective and efficient anticorrosion pigment. In this work, zinc phosphate was u...

This paper deals with the development of acrylic latexes providing high-performance water-resistant coatings. For this purpose, mutual effects anionic surfactant type (ordinary and polymerizable), covalent intra- and/or interparticle crosslinking (introduced by allyl methacrylate copolymerization keto-hydrazide reaction, respectively) ionic (provided nanostructured ZnO additive) were investigat...

A polymeric coating was enlarged by incorporating carbon-based nanofiller such as graphene (GR), oxide, chopped carbon fibers (CF), etc., into the polymer to be utilized for various technological applications. In this framework, acrylic composites and hybrid coatings were made casting a combination of polymer, GR, CF at room temperature. The hybrids composed different ratios (0.25, 0.5, 1, 2 wt...

Hydroxyapatite (HA) nanoparticles are similar to bone apatite in size, phase composition, and crystal structure. When compared with micron-size HA particles, nano-HA possesses improved mechanical properties and superior bioactivity for promoting bone growth and regeneration. However, scaffolds fabricated from nano-HA alone cannot meet the mechanical requirements for direct-loading applications....

BACKGROUND The ability to present signalling molecules within a low fouling 3D environment that mimics the extracellular matrix is an important goal for a range of biomedical applications, both in vitro and in vivo. Cell responses can be triggered by non-specific protein interactions occurring on the surface of a biomaterial, which is an undesirable process when studying specific receptor-ligan...

In recent years, with the development of coating industry and increasing awareness environmental protection, modification waterborne wood coatings has become focus research. Generally, system composed silica sol UV curing can make up for defects poor mechanical properties, low hardness, slow speeds coatings. Herein, we used sol-reinforced UV-curable acrylic tested related physical properties FT...

To improve the overall performance of polyurethane acrylic (PUAs) coatings applied to an iron or wood substrate, a modifier, trivinylisooctyl polyhedral oligomeric silsesquioxane (TVi7iso–POSS), was successfully synthesized by polycondensation reaction in presence organotin catalyst. TVi7iso–POSS is POSS derivative possessing three olefin and seven isooctyl bonds; its molecular structure confir...
