β-cyclodextrin and its hyperbranched polymers-induced micro/nanopatterns and tunable wettability on polymer surfaces
关键字：β-cyclodextrin,hyperbranched polymers,micro/nanopatterns
This paper reports an efficient strategy to fabricate micro/nanopatterns on the surfaces of polymers for obtaining tunable wettability. Tepee-like bundles as micro/nanopatterns, composed of irregular polygon ‘‘podium’’ and ‘‘valley’’ structures, are formed by adding b-cyclodextrin (b-CD) or its hyperbranched polymers [HBP(b-CD)s] into a polystyrene (...

Enhanced nanoflow behaviors of polymer melts using dispersed nanoparticles and ultrasonic vibration
关键字：polymer melts,dispersed nanoparticles,ultrasonic vibration
In the micro/nano fabrication of polymer nanostructures, a key factor is the favorable nanoflow behavior of polymer melts. Compared with the fluidic hydrodynamics of simple liquids through micro- or macrochannels, the nanoflow behavior of polymer melts, however, is affected much more by nanoscale effects and surface interactions. Therefore, achieving a favorable nanoflow of polymer melts in nanoch...

关键字：Poly(ethylene glycol)-b-poly(ε-caprolactone); doxorubicin; drug delivery; micelles; crystallinity; drug-polymer compatibility
This study aimed to optimize poly(ethylene glycol)-b-poly(ε-caprolactone) (PEG-b-PCL) based amphiphilic block copolymers for achieving a better micellar drug delivery system (DDS) with improved solubilization and delivery of doxorubicin (DOX). Firstly, the Flory-Huggins interaction parameters between DOX and the core-forming segments [i.e. poly(ε-caprolactone) (PCL) and poly[(&epsi...
