Abstract In this study, using three types of resins (each with unique material properties) as a matrix, and carbon black (CB) conductive additive, fibres were fabricated through melt-spinning process. An examination the electrical conductivity revealed that CB/polyethylene terephthalate (PET) composite had low percolation value 0.58 wt%, thus highest resin types. These results indicate CB/PET could be used to manufacture antistatic fabrics.
Conventional cancer targeting with nanoparticles has been based on the assumed enhanced permeability and retention (EPR) effect. The data obtained in clinical trials to date, however, have rarely supported presence of such an To address this challenge, we formulated intracellular nitric oxide-generating (NO-NPs) for tumor site-specific delivery NO, a well-known vasodilator, intention boosting EPR. These are self-assembled under aqueous conditions from amphiphilic copolymers poly(ethylene...
Polymer-dispersed liquid crystals (PDLCs), an indispensable class of electrically switchable materials, where nano- or microsized crystal (LC) droplets are phase-separated from the polymer matrix, have been widely used in fabrication highly efficient and systematic smart windows.
