In this study, a temperature responsive PGS/PLLA@PNIPAM core-shell nanofiber membrane was prepared by combining electrospinning with surface ATRP grafting polymer technology, in which the core layer of PGS/PLLA nanofiber was prepared by electrospinning, and then the shell layer of temperature responsive PNIPAM polymer was grafted on the nanofiber surface by ATRP reaction. In the experiment, a macromolecule-initiator PGS-Br was prepared and characterized by FTIR and 1H NMR. The surface morphology, composition, element of the core-shell nanofiber membrane were characterized by SEM, FTIR, and XPS. In addition, it is worth noting that the core-shell nanofiber membrane can respond to temperature in drug release tests.

In this work, hollow carbon nanospheres (HCNs) were synthesized by carbonizing core/shell particles of polymethylmethacrylate (PMMA)/ resorcinol formaldehyde. The core/shell particles were prepared using emulsion polymerization; polymethylmethacrylate as a template and resorcinol-formaldehyde polymer as the carbon source. Spheres were first synthesized by batch mode polymerization and then the shell was polymerized on the surface of the spheres. The composite was stabilized, and then carbonized. The effect of calcination temperature was investigated in the range between 200-500oC. Scanning electron microscopy (SEM), energy-dispersive X-ray spectrometer (EDX), Raman and Fourier transform infrared (FTIR) were used for characterization of the resulting carbon.
