“…Recent studies indicate that incorporating metal nanoparticles, such as silver nanoparticles, into inorganic carriers can enhance nanoparticle dispersion in polymers and mitigate the aggregation of these nanoparticles due to surface effects. This improvement facilitates the optimal utilization of the antibacterial properties of silver nanoparticles ( Liu et al., 2019 ). Common carriers for nano-silver include zinc oxide ( Pham et al., 2021 ), silica ( Wong et al., 2017 ), montmorillonite ( Fernández Solarte et al., 2019 ), zeolite ( Youssef et al., 2019 ), graphene oxide ( Huong et al., 2020 ), and zirconium phosphate ( Liu et al., 2022 ).…”

Polymethyl methacrylate (PMMA) frequently features in dental restorative materials due to its favorable properties. However, its surface exhibits a propensity for bacterial colonization, and the material can fracture under masticatory pressure. This study incorporated commercially available RHA-1F-II nano-silver loaded zirconium phosphate (Ag-ZrP) into room-temperature cured PMMA at varying mass fractions. Various methods were employed to characterize Ag-ZrP. Subsequently, an examination of the effects of Ag-ZrP on the antimicrobial properties, biosafety, and mechanical properties of PMMA materials was conducted. The results indicated that the antibacterial rate against Streptococcus mutans was enhanced at Ag-ZrP additions of 0%wt, 0.5%wt, 1.0%wt, 1.5%wt, 2.0%wt, 2.5%wt, and 3.0%wt, achieving respective rates of 53.53%, 67.08%, 83.23%, 93.38%, 95.85%, and 98.00%. Similarly, the antibacterial rate against Escherichia coli registered at 31.62%, 50.14%, 64.00%, 75.09%, 86.30%, 92.98%. When Ag-ZrP was introduced at amounts ranging from 1.0% to 1.5%, PMMA materials exhibited peak mechanical properties. However, mechanical strength diminished beyond additions of 2.5%wt to 3.0%wt, relative to the 0%wt group, while PMMA demonstrated no notable cytotoxicity below a 3.0%wt dosage. Thus, it is inferred that optimal antimicrobial and mechanical properties of PMMA materials are achieved with nano-Ag-ZrP (RHA-1F-II) additions of 1.5%wt to 2.0%wt, without eliciting cytotoxicity.

“…[8][9][10] The studies on the compositions, properties, morphology and ceramization are concentrated, and some interesting results are revealed by many researchers. In the preparation field of CSRs, polydimethylsiloxane 11 and methyl vinyl silicone rubber (MVSR) [12][13][14] are often selected as the matrix to play a main role in insulation protection. MVSR containing unsaturated double bonds can be beneficial to the irradiation or chemical crosslinking.…”

In the current study, the ceramifiable-silicone-rubber-composites (CSRs) containing allyl-functionalized cyclophosphazene (CP-Allyl) were prepared for studying as novel fire-resistant insulating materials. Electron-beam (EB) irradiation was applied to obtain the cross-linked networks, and the gel content of 98.8% could be achieved at an irradiation dose of 120 kGy. The thermal, mechanical, flame retardancy and insulation properties were well investigated, and it was found that the involvement of CP-Allyl could have a great influence on the properties. The tensile stress of the EB-irradiated CP-Allyl containing composite reached 5.2 MPa, and its limiting oxygen index was up to 32.4%. After ablation at 700-1000 C, it was observed that the shapes of the CSR samples could be well maintained, and the hard and integrated ceramic phases were formed. All the studies indicate that these CSRs may be the promising insulating materials for wires and cables.

“…As a kind of heterochain elastomer, silicone rubber (SR) has been used as the substrate material for ablative composites because of its excellent properties, such as high temperature resistance, pyro-oxidation resistance and shaping [6,7,8,9,10,11]. However, the intrinsic shortcomings of SR, i.e., low mechanical strength and poor carbon residue rate, have restricted its applications [3,12].…”

A novel type of silicon rubber composite with benzoxazine resins (BZs) and ZrO2 was prepared. The ablative response of the composites was investigated. The results showed that the composites with BZs had superior thermal stability and higher resides compared to the pristine composites. The linear ablation rate of the composites decreased significantly with the increase in ZrO2 content. The maximum back-face temperature of the burnt samples was no more than 100 °C for the obtained composites. Three major ablation processes were carried out simultaneously during the ablation processing. These mainly involved the carbonization of the composite, and the formation of ceramic compounds such as SiC and ZrC, as well as the shielding effect of the ablated layer, which subsequently enhanced the ablation resistance of the composites.
