The monomers triethylene glycol dimethacrylate (TEGDMA), 95%, and 2,2-Bis[p-(2′-hydroxy-3′-methacryloxypropoxy)phenylene]propane (Bis-GMA) were both provided by SIGMA-ALDRICH CHEMIE GmbH (Steinheim, Germany). The co-initiator 2-(dimethylamino)ethylmethacrylate (DMAEMA), 99%, and initiator camphorquinone, 98%, were purchased from J&K Scientific GmbH (Pforzheim, Germany). Organically modified silica nanopowder (S.MPS) with 3-(trimethoxysilyl)propyl methacrylate (γ-MPS) was synthesized and subsequently characterized in our previous work [29 (link)]. The commercially available organomodified montmorillonite Nanomer® I.34MN, i.e., an –onium ion modified clay containing 25 to 30 wt% methyl dixydroxyethyl hydrogenated tallow ammonium ion (QA-clay), was produced by Nanocor Company (Hoffman Estates, IL, USA) and supplied by Aldrich (Taufkirchen, Germany). Two experimental QA-clays, namely, a clay type intercalated with cetyltrimethylammonium chloride (MMT-CTAC), as well as its surface-modified analog with 3-(trimethoxysilyl)propyl methacrylate (S.MMT-CTAC), were both prepared and characterized in our previous works [22 (link),30 (link)]. The particular structures of the above QA-clays are presented in Scheme 1 . All other chemicals used were of reagent grade.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
