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...

Surface modification of potassium titanate whisker and its application to thermal insulation coil coatings
Potassium titanate whiskers (PTW) were modified by silane coupling agent KH-570 before and after coating with inorganic SiO2. The influence of the PTWs modified by silane coupling agent before and after coating with SiO2 on thermal insulation performance of coil coating were compared. PTWs before and after modification were characterized by infrared (IR) spectroscopy and thermo-gravimetry (TG). Th...

Al2O3–ZrO2 ceramic coatings fabricated on WE43 magnesium alloy by cathodic plasma electrolytic deposition
Al2O3–ZrO2 ceramic coatings were successfully prepared on WE43 magnesium alloy by cathodic plasma electrolytic deposition (CPED) technique. Surface morphology, elemental and phase composition of the coatings were investigated by scanning electron microscope (SEM), energy disperse spectroscopy (EDS) and X-ray diffraction (XRD). Furthermore, the electrochemical corrosion behavior of the coated...

An emulsifier-free core–shell polyacrylate/diacetone acrylamide emulsion with nano-SiO2 for room temperature curable waterborne coatings
An emulsifier-free core–shell polyacrylate emulsion, containing nano-SiO2 nanoparticles in the core and diacetone acrylamide (DAAM) in the shell, has been successfully prepared by emulsifier-free seeded emulsion polymerization.
The effects of reaction temperature, dropping time, nano-SiO2 and initiator contents, and variation of the composition of core monomers on the amount of coagulum, pa...
