“…The increase in AgNPs could reduce their effective interaction with the polymer, lead to structural disorder of the nanocomposite, and reduce mechanical strength. 13 At higher concentrations, nanoparticles may act as inhibitors of polymerization, reducing the degree of conversion or leaving unreacted monomer within the resin matrix, hence lowering the FS. 25 However, the FS of AgNP groups in this study, except 1-layer 1.5% AgNPs, was found to exceed the ISO 20795-1:2008 (ISO, 2008) recommended value for FS of polymeric materials (65 MPa).…”

“…antimicrobial activity and gained attention in the development of different antibacterial agents. [8][9][10][11][12][13] AgNPs are well tolerated by living tissues, have a low degree of cytotoxicity or genotoxicity in comparison with antibiotics, and tend not to induce microbial resistance. [14][15][16][17][18] Recent studies have investigated materials containing AgNPs and concluded that the bacterial toxicity of silver filler was mainly from damage to cell membranes and disruption of ion homeostasis.…”

“…Это связано с тем, что наночастицы металла могут связываться с молекулами полимера, сшивая их между собой и тем самым увеличивая псевдокристалличность полимера и формируя упорядоченную систему. Однако увеличение концентрации наночастиц в полимере снижает хемосорбционное взаимодействие металлической наночастицы с полимером, что приводит к неупорядоченной структуре нанокомпозита и снижает механическую прочность[17]. При более высоких концентрациях наночастицы могут также действовать как примеси полимеризации, вызывающие снижение степени отверждения.…”
