The wettability of solid surfaces is of fundamental scientific interest and related to many diverse chemical and physical phenomena at the heart of practical technologies. In particular, the hydrophilicity of the photocatalytically active metal-oxide TiO2 has attracted considerable attention for many applications. However, the intrinsic hydrophilicity of Ti-oxide surfaces is not fully understoo...

Hydrophobicity properties of graphite and green synthesized graphene (gsG) from exfoliated graphite/GO towards polymer membrane characteristic and properties at different weight percentage concentrations (1, 2, 3, 4 and 5 wt. %) were investigated. PSf/graphite and PSf/gsG membranes were characterized in term of hydrophobicity, surface bonding, surface roughness and porosity. FTIR peaks revealed...

Poly(dimethylsiloxane) (PDMS) is commonly used for fabricating microand nanofluidic devices due to its low cost and ease of fabrication. The major disadvantage to using PDMS for these applications is its hydrophobic properties. The current methods that enhance the hydrophilicity of elastomers used for microand nanofluidic applications are intricate and cost-inefficient. This contribution demons...

Scaffolds have an important role in cartilage tissue engineering. Poly(hydroxybutyrate‑co‑hydroxyvalerate) (PHBV) has been demonstrated to have potential as a scaffold for the three dimensional construction of engineered cartilage tissue. However, the poor hydrophilicity and mechanical strength associated with PHBV affects its clinical applications as a scaffold in cartilage tissue engineering....

A complete and permanent hydrophilic modification of poly (ethyleneterephthalate) (PET) films is achieved by argon-plasma irradiation, subsequently grafting acrylic acid (AA) in vapor phase onto their surface. Both Ar plasma irradiation alone and post grafting AA rendered a complete hydrophilicity to PET surfaces. However, the hydrophilicity of the PET surface, only treated with the Ar plasma, ...

Changes of titanium surface roughness and surface free energy may influence protein absorption that increases cell differentiation through activation of focal adhesion kinase related pathways. However, the influence of titanium surface roughness and hydrophilicity on fibroblast behavior is not well understood. The aim of this study was to investigate the influence of topography and hydrophilici...

The dynamic hardness of rutile TiO(2) single crystal surfaces was investigated using a nanoindentation technique and the hardness increase was observed only in the near-surface region, possibly due to the volume expansion accompanied by the photoinduced high hydrophilicity.

Magnetic nanoparticles functionalized with maltosylated glycopeptide dendrimers were prepared via azide-alkynyl click reaction. The functionalized magnetic nanoparticles exhibited high hydrophilicity and good efficiency in glycopeptide enrichment by HILIC.

Diamond and diamond-like carbon coatings are used in many applications ranging from biomedicine to tribology. A wide range of dopants have been tested modify the hydrophilicity these surfaces, since this is central their biocompatibility tribological performance aqueous environments. Despite large number experimental investigations, an atomistic understanding effects different on film still lac...

Surface modification on Mg alloys is highly promising for their application in the field of bone repair. In this study, a new metal-organic framework/MgF₂ (Mg-MOF-74/MgF₂) composite coating was prepared on the surface of AZ31B Mg alloy via pre-treatment of hydrofluoric acid and in situ hydrothermal synthesis methods. The surface topography of the composite coating is compact and homogeneous, an...
