| 英文摘要 | Poly(epsilon-caprolactone)-block-poly[2-(dimethylamino)ethyl methacrylate] (PCL-b-PDMAEMA) block copolymers were applied to fabricate elongated polymer platelets with axial length of 5-20 mu m and thickness of ca. 10 nm by crystallization-driven self-assembly (CDSA). The block copolymer platelets composed of a crystallized PCL layer sandwiched between two PDMAEMA layers were obtained spontaneously by adding methanol, a selective solvent of PDMAEMA, into the block copolymer solution of THF at 25 degrees C. Therefore, this is a facile approach to generate lamellar nanoobjects of block copolymers. Effects of the block copolymer compositions on the morphologies of platelets were investigated. The presence of PDMAEMA segments along the lamellar surfaces was further confirmed by loading gold nanoparticles. Moreover, PEO-b-PCL-b-PDMAEMA triblock terpolymer could form spindle platelets by this approach. The crystalline platelets were characterized by the transmission electron microscopy (TEM), scanning electron microscopy (SEM), atomic force microscopy (AFM), small-angle X-ray scattering (SAXS) and wide-angle X-ray diffraction (WAXD).
