“…Ag, AgO and Ag 2 O; (3) the final innermost dense layer of 100 nm includes “Li-containing/Ag-rich” oxides Li x Ag y O z and “Li-free”/“Ag-rich” components. Previously, it was found that mechanical reinforcement could be obtained in soft epoxy materials by adding a slight amount of silver oxide, 10 and interestingly, similar stiffness enhancement is observed in our case.

“…In addition, silver(I) oxide can be found in sensors, optical memories, batteries or capacitors [ 28 , 29 , 30 , 31 , 32 ]. In the case of polymers, silver(I) oxide can be used as a reinforcing filler to epoxy resin, causing an increase in hardness and compression strength and a reduction in wear rate [ 33 ].…”

The purpose of this work was to cross-link chloroprene rubber (CR) with silver(I) oxide (Ag2O) and to investigate the properties of the obtained vulcanizates. Silver(I) oxide was chosen as an alternative to zinc oxide (ZnO), which is part of the standard CR cross-linking system. The obtained results show that it is possible to cross-link chloroprene rubber with silver(I) oxide. This is evidenced by the determined vulcametric parameters, equilibrium swelling and elasticity constants. As the Ag2O content in the composition increases, the cross-link density of the vulcanizates also increases. However, the use of 1 phr of Ag2O is insufficient to obtain a suitably extensive network. Exclusively, the incorporation of 2 phr of Ag2O results in obtaining vulcanizates with great cross-link density. The obtained compositions are characterized by good mechanical properties, as evidenced by high tensile strength. The performed thermal analyses—differential scanning calorimetry (DSC) and thermogravimetry (TGA) allowed us to determine the course of composition cross-linking, but also to determine changes in their properties during heating. The results of the thermal analysis confirmed that CR can be cross-linked with Ag2O, and the increasing amount of oxide in the composition increases the degree of cross-linking of vulcanizates. However, the amount of Ag2O in the composition does not affect the processes occurring in the heated vulcanizate.

Interelastomer Reactions Occurring during the Cross-Linking of Hydrogenated Acrylonitrile-Butadiene (HNBR) and Chloroprene (CR) Rubbers Blends in the Presence of Silver(I) Oxide (Ag2O) and Mechanical Properties of Cured Products

The purpose of this paper was to examine the possibility of producing new blends of hydrogenated acrylonitrile-butadiene and chloroprene rubbers (HNBR/CR) unconventionally cross-linked with silver(I) oxide (Ag2O), and to investigate the physicomechanical properties of the obtained materials. From the obtained results, it can be concluded that HNBR/CR composites were effectively cured with Ag2O, which led to interelastomer reactions, and the degree of binding of HNBR with CR was in the range of 14–59%. The rheometric and equilibrium swelling studies revealed that the cross-linking progress depended on the weight proportion of both elastomers, and the degree of cross-linking was greater with more content of chloroprene rubber in the tested blends. Interelastomer reactions occurring between HNBR and CR improved the homogeneity and miscibility of the tested compositions, which was confirmed by differential scanning calorimetry (DSC) and scanning electron microscopy (SEM) analyses. The tensile strength and hardness of the obtained HNBR/CR/Ag2O vulcanizates proportionally increased with the content of CR, while the tear strength showed an inverse relationship. The obtained new, unconventional materials were characterized by significant resistance to thermo-oxidative factors, which was confirmed by the high aging factor.
