Abstract:
The use of solutions of acrylamide (AAm) opens up new ways for easy one-step synthesis of ZnO nanoparticles (NPs) and their composites with polyacrylamide (PAAm). To obtain a nanocrystalline product in which the composition of NPs is close to {(ZnO)m(Zn2+)n}(CH3COO−)2n with n/m = 0.292, the hydrolysis of Zn(CH3COO)2·2H2O should be carried out in 96% ethanol. In this process, AAm plays the role of an organic base that accepts protons and does not act as a protective ligand. The ZnO NPs/PAAm composite is formed as a viscous transparent colorless hydrogel if the same reaction is carried out in an aqueous medium simultaneously with the radical polymerization of AAm initiated by (NH4)2S2O8. A solid composite can be isolated due to the destruction of the hydrogel by the addition of ethanol. In the composite, PAAm acts as a polymeric matrix in which ZnO NPs are distributed. The synthesis products were characterized by XRD, TEM, SEM, EDX, DLS, IR, Raman scattering, photoluminescence, and chemical analysis. The particles in both products were nanocrystals of hexagonal ZnO about a few nanometers in size. The powder of {(ZnO)m(Zn2+)n}(CH3COO−)2n NPs had a yellow photoluminescence with emission maximum at λem = 590 nm. The photoluminescence band of the ZnO NPs/PAAm hydrogel had a maximum at λem = 449 nm.
