Spherical macroporous poly(lactic-co-glycolic acid) (PLGA) has been synthesised using an emulsion method. Polyvinyl alcohol and Pluronic F127 have been used as dispersing and porogen agent, respectively. The diameter of the spherical PLGA is about 20 μm and the pore size of the PLGA macroporous is about 2–2.5 μm observed by scanning electron microscopy. After immersing in simulated body fluid, the...
A novel hierarchical porous bioactive glasses were synthesised with cattail stem and triblock polyethylene oxide–propylene oxide block copolymer (P123) as macroporous template and mesoporous template, respectively. The structural and textural properties of materials were characterised by X-ray diffraction, scanning electron microscope, Fourier transform infrared spectroscopy, nitrogen adsorption–desorption,...
