Surface Improvement of Halloysite Nanotubes

A novel development on halloysite-polyvinyl alcohol (HNTs-PVA) nanocomposites has been conducted using malonic acid (MA) by crosslinking PVA and HNTs. PVA-MA crosslinking produces smooth surfaces, which play an important role in enhancing the properties of HNTs-PVA nanocomposite. The crystallographic structures of crosslinked HNTs-PVA show almost no change as depicted by the X-ray diffraction (...

Cellular interactions of doxorubicin-loaded DNA-modified halloysite nanotubes.

Halloysite nanotube (HNT)-based supramolecular complexes are synthesized and evaluated with respect to their cytotoxicity and effects on cellular structures. As HNTs are water-insoluble, DNA is applied for wrapping the surface of HNTs to enhance their water-dispersibility. To investigate the potential of DNA-wrapped HNTs (HD) as a promising drug delivery carrier, doxorubicin (DOX) is introduced...

Mechanochemically Responsive Viscoelastic Elastomers

Mechanochemically responsive (MCR) polymers have been designed to possess unconventional properties such as changing colors, self-healing, and releasing catalysts under deformation. These properties of MCR polymers stem from a class of molecules, referred to as mechanophores, whose chemical reactions can be controlled by mechanical forces. Although extensive studies have been devoted to the syn...

Preparation and characterization of TiO2 nanoparticles surface-modified by octadecyltrimethoxysilane

Titanium dioxide (TiO2) nanoparticles surface-modified by octadecyltrimethoxysilane (commercial name WD-11) are prepared via in situ surface-modification in dehydrated ethanol at room temperature. As-obtained TiO2 nanoparticles are characterized by means of Fourier transform infrared spectrometry, thermogravimetric, X-ray diffraction and transmission electron microscope. The tribological proper...
