In this thesis, monomer with unsaturated double bond was firstly synthesized byreacting acryloyl chloride with bifunctional monomer. Such synthesized monomer ormonomer with initial unsaturated double bond was used to prepare linear polymericmaterials by free radical polymerization. A series of new degradable space polymerswith acylamino bond were subsequently synthesized using diisocyanate as thecross-linker.

We also for the first time compared the the storage stability of the allylamine plasma samples in the different mediums , including the hydrophilicity and biocompatibility, and the results indicated the samples had good stability in the different mediums.

同时还首次比较了丙烯胺等离子体修饰样品在多种不同介质中的储存稳定性，包括亲水性和生物相容性，结果显示样品在不同介质中均有较好的稳定性。

Secondly, the pulse discharge plasma with allylamine was discussed, and the modification results with two kinds of discharge models were compared. The results showed that discharge models had influences on the plasma treatment results, especially under lower pressure and higher temperature with pulse discharge. The nitrogen element content in the layer under the pulse discharge was obviously lower than that under the continuous discharge, but there was higher proportion NH〓 groups remaining in the layer under the pulse discharge. The sample surfaces obtained by pulse discharge also had good biocompatibility.

其次讨论了脉冲放电模式下丙烯胺单体的等离子体修饰，比较了两种放电模式对修饰结果的影响，研究结果显示，放电模式对表面修饰层的结果有一定的影响，其中脉冲放电对低压及高温两等离子体条件下的影响尤为明显；脉冲放电下所得到的修饰层中的氮元素含量明显低于连续放电模式下，而脉冲放电下有较高比例NH〓基团保留在修饰层中；脉冲放电所得到的表面修饰层同样有较好的生物相容性。

The deposition thickness of allylamine was increased with the treating time. The surface textures were changed following different procedures except allylamine groups and it means that the 30 min deposition thickness of allylamine is too thin to change the surface contours.

SEM-EDS的结果显示在未经任何处理及经氩气电浆清洁后的钛金属表面，侦测到主要为钛元素，丙烯胺电浆处理后，即可测到氮元素；戊二醛作用后表面有氧元素的出现；白蛋白处理后即可测得碳及氧元素。

During the low temperature plasma polymerization, different factors (reaction power, pulse duty factor, reaction time, bias voltage and pressure) were investigated to get the best film. The results of X-ray photoelectron spectroscopy and Fourier transformed infrared spectoscopy implied that polymer nano-film containing carboxyl or amido were deposited successfully by using allylamine or acrylic acid as a reagent, respectively.

低温等离子聚合过程中，研究了反应的功率、脉冲占空比、反应时间、偏压、反应室压强这五个因素对薄膜性质的影响，确定了最佳的工艺参数。X光电子能谱和傅立叶转换红外光谱分析结果表明，以丙烯胺和丙烯酸为反应物可以在样品表面分别得到含有羧基或氨基的有机薄膜。
