Samples were prepared from mixtures of tetraacetoxysilane and the corresponding organically modified alkoxide RTES (R = Ph (phenyl) and pFPh (pentafluorophenyl)) in the appropriate ratio to obtain ormosil matrices. The maximum R/Si molar ratios used for sample preparation were 0.9 and 0.7 for Ph and pFPh functionalized samples respectively, as larger amounts of organic functional substituents in the matrices resulted in the formation of opaque films. 以上是我看的一個(gè)文獻(xiàn)的一部分,我怎么沒明白他說的啥意思呀,還是我英語比較差。。 我剛接觸者方面 我看很多文獻(xiàn)都是直接硅酸乙脂加醇再加點(diǎn)酸就完了呀 這個(gè)怎么還有機(jī)修飾下? 這也沒說加有機(jī)溶劑呀,取代的什么? 求高手指點(diǎn)下這個(gè)是什么意思 [ Last edited by diablewow on 2010-11-15 at 10:08 ] |
