(J. Coat. Technol. Res.)Effects of solvents on the curing and properties of fully bio-based thermosets for coatings
With the increasing concern about the depletion of fossil reserves and greenhouse gas emissions, it is desired to replace coatings which are made using petrochemical-based materials with renewable alternatives such as bio-based polymers. In this paper, fully bio-based thermosets for coatings were prepared from epoxidized sucrose soyate (ESS) derived from sucrose an...

Chitosan/titanium dioxide nanocomposite coatings: rheological behavior and surface application to cellulosic paper
Incorporation of nanofillers into a polymeric matrix has received much attention as a route to reinforced polymer nanocomposites. In the present work, an environmentally friendly chitosan (CTS) /titanium dioxide (TiO2)
nanocomposite coating was designed/prepared and subsequently employed for imparting antibacterium and
improved mechanical properties to cellulosic paper via s...

Multifunctional cotton fabrics with graphene/polyurethane coatings with far-infrared emission, electrical conductivity, and ultraviolet-blocking properties
In order to introduce multifunctional properties into flexible cotton fabric, graphene and waterborne anionic aliphatic polyurethane composites were prepared and then deposited on the surface of the fabric substrate through facile pad-dry-cure process. The fabrics thus obtained were characterized by scanning electron microscopy and Fourier transform infrared spectroscopy, and their functional prop...

Double-layered reactive microcapsules with excellent thermal and non-polar solvents resistance for self-healing coatings
Double-layered polyurea microcapsules containing hexamethylene diisocyanate (HDI) with outstanding shell tightness have been successfully synthesized via interfacial polymerization reaction in an oil-in-water emulsion. The resultant capsules were systematically characterized by scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and Fourier...

Macroporous Biphasic Calcium Phosphate Scaffolds Reinforced by Poly-L-lactic acid/Hydroxyapatite Nanocomposite Coatings for Bone Regeneration
Three-dimensional
(3D) interconnected porous scaffolds with biomimetic hierarchical architectures
and mechanical characteristics are critical for the success of bone
regeneration. In this paper, biphasic calcium phosphate (BCP) scaffolds were
coated with medical-grade poly-L-lactic acid/hydroxyapatite
(mPLLA/HA) nanocomposites to create controlled surface roughness while
remaining the interconnect...

A Versatile Approach towards Multifunctional Robust Microcapsules with Tunable, Restorable, and Solvent-Proof Superhydrophobicity for Self-Healing and Self-Cleaning Coatings
Numerous microencapsulation techniques have been developed to encase various chemicals, for which specific processing parameters are required to address the widely differing features of the encapsulated materials. Microencapsulation of reactive agents is a powerful technique that has been extensively applied to self-healing materials. However, the poor solvent compatibility and insufficient ther...

Robust microcapsules with polyurea/silica hybrid shell for one-part self-healing anticorrosion coatings
Silica/polyurea hybrid microcapsules loaded with hexamethylene diisocyanate (HDI) as core materials were prepared via a combined strategy of interfacial polymerization and an in situ sol-gel process in an oil-in-water emulsion. They were clearly characterized by scanning electron microscopy. Fourier transform infrared spectroscopy, and X-ray photoelectron spectroscopy. The resultant microcapsule...

Comparative study on the optical, surface mechanical and wear resistant properties of transparent coatings filled with pyrogenic and colloidal silica nanoparticles
We applied two kinds of silica nanoparticles, i.e. colloidal and pyrogenic ones, to improve the performance of transparent coatings on polymer substrates. The urethane–acrylate oligomer was mixed with varied concentrations of silica nanoparticles, spin-coated onto polycarbonate substrate and finally cured by ultraviolet rays. The resultant thickness of the coatings can be controlled in ...

High-refractive-index transparent coatings enhance the optical fiber cladding modes refractometric sensitivity
The high order cladding modes of standard single mode optical fiber appear in quasi-degenerate pairs corresponding to mostly radially or mostly azimuthally polarized light. In this work, we demonstrate that, in the presence of a high-refractive-index coating surrounding the fiber outer surface, the wavelength spacing between the orthogonally polarized cladding modes families can be drastically enh...
