Electrospun PLA: PCL composites embedded with unmodified and 3-aminopropyltriethoxysilane (ASP) modified halloysite nanotubes (HNT)

Strengthening and stiffening carbon fiber epoxy composites by halloysite nanotubes, carbon nanotubes and silicon carbide whiskers

Effect of annealing on the mechanical properties of PLA/PCL and PLA/PCL/LTI polymer blends.

The effects of annealing on the mechanical properties of polymer blends of poly(lactic acid) (PLA) and poly(ε-caprolactone) (PCL) were investigated. The bending strength and modulus of PLA/PCL tend to increase due to crystallization of the PLA phase by annealing. The mode I fracture energy, J(in), of PLA/PCL decreases dramatically due to the suppression of the ductile deformation of the spheric...

Electrospun poly(vinyl alcohol) composite nanofibers with halloysite nanotubes for the sustained release of sodium dpantothenate

Poly(vinyl alcohol) (PVA) nanofibers containing halloysite nanotubes (HNTs) loaded with sodium D-pantothenate (SDP) were successfully fabricated via simple blend-electrospinning. SDP was efficiently loaded into the innate HNT lumen with an SDP/ HNT mass ratio of 1.5:1 via vacuum treatment. The SDP-loaded HNT-inclusion complex was evaluated with drug-loading efficiency testing, Fourier transform...

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...

Electrokinetic and adsorption properties of sepiolite modified by 3-aminopropyltriethoxysilane.

Surface modification of clay minerals has become increasingly important for improving the practical applications of clays such as fillers and adsorbents. An investigation was carried out on the surface modification of sepiolite with aminopropylsilyl groups in 3-aminopropyltriethoxysilane (3-APT). The zeta potential of the modified sepiolite suspensions was measured as a function of initial elec...
