本文用傅里叶变换红外光谱（FTIR）研究了1%的γ-甲基丙烯酰氧丙基三甲氧基硅烷（MPS）在水溶液中的水解过程。这项工作的目的是确定的水解时间，为更大数量的Si-OH基团已获得。研究了在pH 4下的不同水解时间，以确定粘合到基材的最佳应用条件。可以观察到对应于纯硅烷光谱中存在的Si-O-C基团的谱带在短时间水解后如何继续出现。然而，这些频带几乎消失后，增加了这一水解时间，与其他新的出现相应的Si-OH振动。对6063铝合金进行了硅烷化处理。通过FTIR对硅烷层的分析表明，根据水解条件，浸泡时间可能是重要的，并且它还允许优化干燥时间。(C)2009 Elsevier B. V.保留所有权利。
In this paper the hydrolysis process of gamma-methacryloxypropyltrimethoxysilane (MPS) at 1% in an aqueous solution by means of Fourier transform infrared (FTIR) spectroscopy was studied. The aim of this work is to determine the hydrolysis time for which a greater number of Si-OH groups has been obtained. Different hydrolysis times at pH 4 were studied to establish the most optimal application conditions for bonding to the substrate. It was possible to observe how the bands corresponding to the Si-O-C groups present in the pure silane spectrum continued to appear after short periods of hydrolysis. However these bands practically disappeared upon increasing of this hydrolysis time, with other new ones appearing corresponding to the Si-OH vibration. The silanization of 6063 aluminum alloy samples was also carried out. Analysis of the silane layers by means of FTIR indicated that the immersion time may be important according to the hydrolysis conditions, and it also allowed optimizing the drying time.
