报道了一种在玻璃微毛细管内壁上沉积稳定的氨基功能膜的微等离子体共聚技术。以乙二胺(EDA)、3-氨基丙基三乙氧基硅烷(APTS)和六甲基二硅氧烷(HMDSO)为有机前驱体进行了共聚反应。利用独创的液体注入和螺旋混合技术，精确地给出了血浆中单体混合物的比例。EDA-HMDSO制备的涂层比EDA和APTS制备的涂层更稳定。用X射线光电子能谱、傅里叶变换红外光谱、紫外可见光谱、原子力显微镜和生长速率测量等手段对薄膜进行了表征。通过水接触角和表面自由能的测量分析了薄膜的疏水和亲水特性。用这种方法制备的涂层在水介质中的稳定性表明，它们可以用于生物和微流体应用。(C)2014爱思唯尔B.V.保留所有权利。
We report a technique of microplasma copolymerization for depositing a stable amino functional film on the inner walls of a glass microcapillary. The monomers ethylenediamine (EDA), 3 aminopropyltriethoxysilane (APTS) and hexamethyldisiloxane (HMDSO) were used as organic precursors for copolymerization. The ratio of the monomer mixture in the plasma was precisely fed using an original technique of liquid injection and helical mixing. The coatings obtained from EDA-HMDSO were found to be more stable than those produced using EDA and APTS. The films were characterized using X-ray photoelectron, Fourier transform infrared and UV-vis spectroscopy, atomic force microscopy and growth rate measurements. The hydrophobic and hydrophilic characteristics of the films were analyzed through water contact angle and surface free energy measurements. The stability of the coatings formed using this method in aqueous media indicated that they could be utilized for biological and microfluidic applications. (C) 2014 Elsevier B.V. All rights reserved.
