In this manuscript, the novel sodium alginate-g-poly [acrylic acid–N-(3-dimethylaminopropyl) methyl acrylamide] [NaAlg-g-P(AA-co-DMAPMA)] hydrogel was prepared using free radical polymerization. Fourier transform infrared spectroscopy (FT-IR), thermogravimetry (TG), point zero charge and scanning electron microscopy were used to investigate the structure, thermal stability, surface charge and microstructure...
A new series of core–shell structured silver/polyimide (PI) nanocomposites was prepared by in situ polymerization followed by the chemical imidization of poly(amic acid) (PAA, precursor of PI) at a low temperature. The TEM images showed that the silver cores of the nanocomposites were encapsulated with homogeneous shells with thickness of 4 and 8 nm at silver contents of 90 and 60 %, respectively...
