X-ray study of structural formation, thermomechanical and antimicrobial properties of copper-containing polymer nanocomposites obtained by the thermal reduction method

Effect of the type of reducing agents of silver ions in interpolyelectrolyte-metal complexes on the structure, morphology and properties of silver-containing nanocomposites

“…Within the last decades, interest in studying of nanodimensional particles of various metals is constantly grown 1,2 . First of all, it is explained by their unique optical, electronic, catalytic and other properties, which sharply distinguish them from their analogs -microscale objects.…”

Antimicrobial Polymeric Structures Assembled on Surfaces

“…A prominent category of such structures is represented by drug-loaded and gel-like structures [ 42 , 53 , 99 , 100 , 101 , 102 ]. Another equally important category of antimicrobial structures includes those obtained from polymeric systems assembled on specific surfaces [ 103 , 104 , 105 , 106 , 107 , 108 , 109 , 110 , 111 , 112 , 113 , 114 , 115 , 116 ]. In this work, we further review only the most recent antimicrobial structures falling within the last category.…”

“…This composite was able, after 1 h of contact, to reduce about 80%, 87% and 96% of attached live E. Coli , P. aeruginosa and S. aureus bacteria, respectively ( Figure 10 d). The second example is depicting a Cu-containing polymer film composite prepared by thermal reduction of Cu 2+ ions to metallic Cu in the pectin–Cu 2+ –PEI interpolyelectrolyte–metal complexes, i.e., by transferring electrons from the nitrogen atoms of amino groups of PEI to Cu 2+ ions accompanied by the destruction of the metal-based complexes [ 115 ]. Resulting pectin-PEI-Cu heterogeneously structured composite exhibited better antimicrobial attributes against S. aureus and E. coli than did its counterpart pectin-PEI.…”

Structure and Thermophysical Properties of Polymer Composites Based on Oligomers of Various Molecular Weight

“…Гетерогенну структуру (на нанорозмірному рівні) зазначених полімерних систем досліджували методою малокутового розсіяння Рентґенових променів за допомогою камери ÊРМ-1, оснащеної щілинним коліматором первинного пучка випромінювання, виконаним за методою Êратки. Геометричні параметри камери задовольняють умові нескінченної висоти первинного пучка [15]. Профілі інтенсивности нормували на величину об'єму розсіяння Рентґенових променів і фактор послаблення первинного пучка досліджуваним зразком.…”
