Study of the structure of a polyacrylic acid-Cu (II)-poly-4-vinylpyridine ternary polymeric metal complex

Preparation, structure and properties of metal–copolymer complexes of poly-4-vinylpyridine radiation-grafted onto polymer films

“…In another publication, Kabanov et al reported on studying the structure of polyacrylic acid-Cu(II)-P4VP metal complex. Spectrophotometric and EPR analyses showed that the complex formation depended on both the conformation state of the cuprous ion in the co-ordination sphere and number of functional groups involved in the process [4].…”

Interpolyelectrolyte Complexes Based on Polyionic Species of Branched Topology

“…Some examples include effective and available binders for dispersed systems and flocculants of colloidal dispersions [2], biocompatible coatings [3,4], components of membranes [5][6][7][8][9][10][11], carriers of biologically active compounds (including enzymes and DNA) [12][13][14][15][16], matrices for metal ions and metal nanoparticles [17][18][19][20][21][22], and the formation of multilayered PE films and capsules using layer-by-layer techniques [23][24][25][26][27][28][29][30][31][32].…”

The peculiarities of formation of the metal nanoparticles in irradiated polymer metal complexes

“…The reduction processes were investigated for the films with different composition (9PAA:1PEI, 1PAA:1PEI, 1PAA:9PEI) where the initial concentration of Cu 2+ ions was 6 or 3 wt.%. The assignment of lines in the complex EPR spectra resulting from anisotropic g-tensor and hyperfine interaction was made according to the data presented elsewhere [10] and will not be discussed in detail here. The complexes under consideration may include Cu 2+ ions in different ligand environment: with four imine groups (I), with four imines groups and salt bonds (no coordination) (II), with two carboxylate groups (III), and with two imine groups and two carboxylate groups (IV).…”

“…The magnetic resonance parameters of complexes of Cu 2+ ions with PAA and PEI were analyzed in detail previously [10]. This justifies the choice of PAA-PEI-Cu 2+ complexes as a basic model system for EPR investigation of the peculiarities of ion reduction in triple polymer metal complexes.…”
