The tensile properties of poly (l-lactic acid) (PLLA) and polycaprolactone (PCL) composites filled with nanometer calcium carbonate (nano-CaCO 3 ) were measured at room temperature and different tensile rates. With increase of the PCL weight fraction, the tensile elastic modulus, tensile strength and tensile strength at fracture for the PLLA/PCL/nano-CaCO 3 composites decreased nonlinearly,...
The key problems faced in developing indwelling catheters are how to incorporate antibacterial agents into the substrate and how to improve the antibacterial effectiveness. In this study, an antibacterial composite coating layer is inversely in situ formed on the silicone substrate by a novel technique involving deposition of an antibacterial agent, solution casting and crosslinking of a silicone...
