Electrospun nanofibers: A nanotechnological approach for drug delivery and dissolution optimization in poorly water-soluble drugs
(International Association of Physical Chemists, 2020)
Electrospinning is a novel and sophisticated technique for the production of nanofiberswithhigh surface area, extreme porous structure, small pore size, and surface morphologies that make them suitable ...
Composites of carbon nanofibers and thermoplastic polyurethanes with shape-memory properties prepared by chaotic mixing
(Wiley Inter Science, 2009)
Composites of carbon nanofibers (CNFs), oxidized car bon nanofibers (ox-CNFs), and shape-memory thermo plastic polyurethane (TPU) were prepared in a chaotic
mixer and their shape-memory properties evaluated.
The polymer ...
Kinetics of Isothermal Degradation Studies in Adhesives by Thermogra vimetric Data: Effect of Hydrophilic Nanosilica Fillers on the Thermal Properties of Thermoplastic Polyurethane-Silica Nanocomposites
(Recent Patents on Nanotechnology, 2008)
The kinetics of thermal degradation process on thermoplastic polyurethanes (TPUs) adhesives with hydrophilic
nanosilicas was studied using isothermal thermogravimetric analysis within the temperature range from 360 °C ...
Analysis of energy transfer and ternary non-covalent filler/matrix/UV stabilizer interactions in carbon nanofiber and oxidized carbon nanofiber filled poly(methyl methacrylate) composites
(Elsevier, 2011-10-27)
Ternary non-covalent interactions between carbon nanofibers (CNFs), oxidized carbon nanofibers (ox-
CNFs), poly(methyl methacrylate) (PMMA) chains, and benzotriazole-containing UV stabilizers were
analyzed using ...
