SiO 2 /Poly(3-aminophenylboronic acid) (PAPBA) composites were synthesized under different experimental conditions, using ultrasonic irradiation method. Polymerization was carried out in the presence of sodium fluoride and D-fructose to anchor 3-aminophenylboronic acid groups on to SiO 2 surface. The SiO 2 /PAPBA nanocomposite prepared by NaF and D-fructose in the polymerization medium was found to show different morphology, electrical properties, thermal behavior and structural characterization in comparison to the nanocomposites prepared under other conditions. Ultrasonic irradiation minimizes the aggregation of nanosilica and promotes anchoring of PAPBA units over SiO 2 surface. The morphology of PAPBA/ SiO 2 nanocomposite was investigated by using transmission electron microscopy, UV-visible spectroscopy; thermogravimetric analysis, Fourier transform infrared spectroscopy, and X-ray diffraction analysis were used for characterization. Transmission electron microscope of the nanocomposites observation shows that SiO 2 /PAPBA composite, prepared with D-fructose and NaF under ultrasonication has a core-shell morphology. The thermal and crystalline properties of core-shell SiO 2 /PAPBA nanocomposite was prepared via ultrasonication method is different from the SiO 2 /PAPBA nanocomposite prepared via conventional stirring method, in which SiO 2 nanoparticles are submerged in PAPBA. Conductivity of the composite prepared via ultrasonication shows around 0.2 S/cm.

“…In the in situ methods, metal particles are generated inside a polymer matrix by decomposition or chemical reduction of a metallic precursor dissolved into the polymer. 18 For example, silver ions are successfully reduced and dispersed in poly(vinyl pyrrolidone) (PVP), poly(vinyl alcohol), and poly(2-hydroxyethyl methacrylate) matrices. Another method was used to prepare polymer-silver nanoparticle composites with g-irradiation, in which Ag 1 reduction and the polymerization of monomer took place simultaneously.…”

A series of antibacterial superabsorbents containing silver nanoparticles based on sodium acrylate (SA), 1-vinyl-2-pyrrolidone-silver ion complex (VP-Ag 1 ) and N, N 0 -methylene-bisacrylamide (NMBA) were prepared by inverse suspension polymerization. The ascorbic acid (vitamin C) was used as reductant to reduce silver ion complex in the gels through in situ reduction method. The influence of the concentration of VP-Ag 1 complex in the superabsorbents on the water absorbency, swelling behavior, and antibacterial effect of Candida albicans was investigated. Results showed that the water absorbency for sodium acrylate and VP copolymeric gel (SV gel) in deionized water was 1016 g H 2 O/g gel, but the water absorbency for SV-Ag series gel decreased when the silver nanoparticle was added. Results also showed that the antibacterial effect of the superabsorbents increased with an increase of the silver concentration (1 $ 10 ppm).
