Controlled radiation-chemical synthesis of metal polymer nanocomposites in the films of interpolyelectrolyte complexes: Principles, prospects and implications
2020, Radiation Physics and ChemistryCitation Excerpt :In recent years, the progress in the synthesis of metal–polymer nanostructures by different methods was associated with the use of coatings and films of IPECs (Pergushov et al., 2014; Shi et al., 2004; Demchenko et al., 2017a, 2017b). Different combinations of polyanions and polycations were used for the preparation of films and soluble metal-polymer hybrids: poly(acrylic acid) - polyethyleneimine (PAA-PEI) (Dai and Bruening, 2002; Feldman et al., 2013; Klimov et al., 2018; Lei et al., 2008; Zezin et al., 2010); PAA-polyallylamin (Bakar et al., 2012, 2014); pectin and PEI (; Demchenko and Shtompel’, 2014) PAA - poly(allylaminehydrochloride) (PAH) (Bruening et al., 2008; Wang et al., 2002, 2003). The advantages of synthesis of metal nanoparticles in multilayer polyanion-polycation systems (IPECs) and the development of this method were discussed previously (Shi et al., 2004).
Radiation-induced preparation of metal nanostructures in coatings of interpolyelectrolyte complexes
2019, Radiation Physics and ChemistryCitation Excerpt :The use of chemical approaches for the reduction of metal ions in such systems resulting in formation of the nanoparticles of silver and noble metals was reported previously (Dai and Bruening, 2002; Macanás et al., 2010; Dotzauer et al., 2009). Recently silver or copper nanoparticles and bimetallic nanostructures were synthesized in solutions and films of interpolyelectolyte and interpolymer complexes irradiated in water-alcohol media using accelerated electrons, γ- or X-ray irradiation (Bakar et al., 2012, 2014; Klimov et al., 2018; Feldman et al., 2013; Zezin et al., 2011a) It should be noted that the metal ions are strong absorbers for X-ray photons in the energy range up to several tens of keV, which results in significant increase in the absorbed dose rate for metal polymer complexes. The intensification of nanoparticle assembling in the systems with high content metal ions makes it possible to use X-ray irradiation for effective production of the metal-polymer film nanocomposites (Feldman et al., 2013; Zezin et al., 2009, 2011b).
Nanocomposites based on interpolyelectrolyte complex and Cu/Cu<inf>2</inf>O core-shell nanoparticles: Structure, thermomechanical and electric properties
2016, European Polymer JournalCitation Excerpt :Copper’s nanoparticles possess an interesting optical properties, high catalytic, antibacterial and fungicide activities and this urges an interest for design and preparing a metallo-polymer and hybrid composites, having controllable structure and particles of nano-size level. In the last decade, researches dealing with elaboration of such hybrid materials [18–21], including synthesis of Cu-nanoparticles directly in a polymers films [11,22,23], are intensively developed. In particular, in the publications [8,23,24] structure and physico-mechanical characteristics of nanocomposites based on interpolyelectrolyte complex (IPEC), like polyacrylic acid–polyethyleneimine and Cu2O nanoparticles were studied.
