Preparation of Silica Nanoparticles Through Microwave …
Silica is a dielectric material of great interest for industrial appliions because of its properties- highly transparent, highly functional surface, and low toxicity 28-33. The microwave-assisted techniques presented in this manuscript have significance over existing methods because they provide a quick and reproducible synthesis for SiO 2 NPs with varying diameters under microwave heating

15/9/2011· It is true that modifiion of silica particles with thiols makes them somewhat more hydrophobic compared with unmodified silica particles [32, 45]. The contact angles of self-asseled MPTMS on silicon oxide are 71° and 84° for the well-ordered and partially ordered structures, respectively [ 45 , 46 ], but the contact angle for CPTMS has a similar value of about 80° [ 46 ].
