“…One of the most popular and applicable coupling agents is silane coupling agents. The coupling process can be accomplished via the chemical reaction between the trialkoxy groups of silane molecules and the hydroxyl groups on the nanoparticles, whereas other functional groups of silane molecules, which are generally ethylene, amine, epoxy, thiohydroxy, etc., remain intact [20][21][22].…”

In this study, various optically active poly(ester-amide)/Zinc oxide bionanocomposites (PEA/ZnO BNCs) were synthesized with different amount of modified ZnO nanoparticles using ultrasonic irradiation. To obtain the homogeneous distribution of ZnO in polymer matrix, the surface of nanoparticles was modified to organophile with c-aminopropyltriethoxyl silane. PEA/ZnO BNCs were characterized by Fourier transform infrared spectra, X-ray diffraction, field emission scanning electron microscopy (FE-SEM), atomic force microscopy (AFM), and transmission electron microscopy (TEM). The FE-SEM, AFM, and TEM results confirmed that the nanoparticles were dispersed uniformly in PEA matrix at the nanoscale. In addition, thermogravimetric analysis data indicated an improvement of thermal stability of novel BNC materials as compared to the pure polymer.

“…38,39 Upon the in situ growth of silver nanoparticles by UV irradiation, the T g of PS remained almost invariant at 49 o C whereas that of PECH increased from -15 to -1.6 o C. This result strongly demonstrates that silver nanoparticles selectively interact with ethylene oxide moiety of PECH domains, leading to the restricted chain mobility and T g elevation of nanocomposites. 40,41 Conclusions Amphiphilic PECH-g-PS graft copolymer with 34:66 wt% was successfully synthesized via ATRP technique using PECH backbone as a macroinitiator and used as a template film for the self-assembled formation of silver nanoparticles at solid sate. The nanocomposites consisting of amphiphilic graft copolymer and silver nanoparticles were constructed under UV irradiation through an in situ reduction of silver ions dissolved in microphase-separated PECH-g-PS template film.…”

This work has demonstrated that a novel amphiphilic poly(epichlorohydrine)-graft-polystyrene (PECHg-PS) copolymer at 34:66 wt% was synthesized via atom transfer radical polymerization (ATRP) of styrene using PECH as a macroinitiator. The structure of the graft copolymer was characterized by nuclear magnetic resonance ( 1 H NMR) and FTIR spectroscopy, demonstrating that the "grafting from" method using ATRP was successful. The self-assembled graft copolymer was used as a template film for the in-situ growth of silver nanoparticles from AgCF 3 SO 3 precursor under UV irradiation. The in situ formation of silver nanoparticles with 6-8 nm in average size in the solid state template film was confirmed by transmission electron microscopy (TEM), UV-visible spectroscopy and wide angle X-ray scattering (WAXS). Differential scanning calorimetry (DSC) also displayed the selective incorporation and the in situ formation of silver nanoparticles within the hydrophilic PECH domains, probably due to stronger interaction of the silvers with the ether oxygens of PECH backbone than that with hydrophobic PS side chains.

Recent advances in the field of nanotechnology led several groups to recognize the promise of recruiting nanocomposities to the ongoing battle against pathogenic gram-positive and gramnegative bacteria and metal-polymer nanocomposites are a typical example. On the basis of recent literature, the nanocomposities are synthesized mainly by two techniques i.e. in-situ and ex-situ technique and these nanocomposities have great biomedical applications in terms of their antibacterial activity. A large battery of newly developed and discovered nanocomposities has been accumulating during the last decade.
