China, 510006摘 要I摘 要本论文主要是对 PET 薄膜进行臭氧处理，然后再接枝以获得较好的亲水性和吸附活性，从而使化学镀铜反应顺利进行。本论文的研究主要有三个部分，第一部分是PET 薄膜的臭氧处理；第二部分是 PET 薄膜的改性，包括液相光接枝改性和液相热接枝改性；第三部分是臭氧处理并经过接枝改性 PET 薄膜的化学镀铜。PET 薄膜的臭氧处理以水作为载体，将 PET 薄膜完全浸泡在其中，讨论了臭氧气流量和处理时间和处理温度对 PET 薄膜处理效果的影响，并得出了三者的最佳值。液相光接枝以丙烯酰胺作为接枝单体，硝酸铈铵为引发剂，讨论了单体浓度、引发剂浓度和接枝时间对液相光接枝的影响，并得出了上述三个因素的最佳值。在最佳值的条件下，所获得的最大接枝率约为 2.3%。热接枝也以丙烯酰胺为接枝单体，过硫酸钾为引发剂，讨论了丙烯酰胺浓度、引发剂浓度、温度和接枝时间对热接枝的影响，确定了上述四个因素的最佳值。在最佳值的条件下，所获得的最大接枝率约为 3.9%。通过对比液相光接枝和热接枝，发现热接枝可以获得更大的接枝率，相关的数据、红外光谱和 X 射线衍射以及扫描电镜均证明了这一点。通过对比光接枝和热接枝 PET 薄膜在化学镀铜的特点，发现热接枝 PET 薄膜可以实现孔内和双面镀铜，而光接枝 PET 薄膜很难实现。而且热接枝 PET 薄膜在起镀时间和镀铜均匀性上表现更好。为了提高化学镀铜的质量，研究了亚铁氰化钾，聚乙二醇-12000 和 2,2-联吡啶对化学镀铜质量的影响，发现三者的最佳值分别为 4 mg/L、60 mg/L 和 15mg/L。在上述条件下，所制得的化学镀铜光泽度好，镀铜纯净致密，颗粒细小，结合力表面电阻和厚度均达到要求，可以用来生产挠性电路板。关键词：化学镀铜，接枝改性，PET 薄膜，臭氧，丙烯酰胺广东工业大学硕士学位论文IIAbstractIIIAbstractOzone treatment and grafting of PET film to achieve good activity which makes the reaction of electroless cooper plating takes place smoothly is the main purpose of the paper. This paper is made of three parts. The first part is the ozone treatment of PET film; the second part is the grafting and modification of PET film, which includes photografting and thermal grafting; the last part is the electroless cooper plating of ozone-treated and modified PET film.The ozone treatment of PET took place in the water. The effect of ozone gas flow, time and temperature on the performance of PET film was discussed.In the photografting reaction, arcylamide was selected as monomer; ceric ammonium nitrate was chosen as initiator. effect of concentration of monomer，initiator and reaction time on the grafting of PET was discussed，In the thermal grafting reaction，arcylamide was used as monomer; potassium peroxodisulfate was used as initiator. Effect of concentration of monomer，initiator，and temperature and reaction time on the grafting of PET was discussed.Compared the photografting reaction with thermal grafting reaction，a larger grafting degree can be achieved by the later，which was also proved by IR spectra, XRD and SEM.Compared the difference of photografted PET film with thermalgrafted PET film in electroless cooper plating， double-face and hole electroless cooper plating is easy for the later but hard for the former. Moreover ，the later does well in the time of starting electroless cooper plating and the uniformity of cooper plating.In order to improve the quality of electroless cooper plating，the effect of potassium ferrocyanide，PEG-12000 and 2,2-bipyridine on quality of electroless cooper plating was studied and the optimum value was 4mg/L,60mg/L and 15mg/L respectively. In the condition above，the electroless cooper plating was compact, small and pure with a good glossiness, adhesive, thickness and surface res
