I have studied surface modification of poly (ethylene terephthalate)(PET) in order to add several new functions such as pleasant feel and antibacterial property without loss of the excellent mechanical properties such as strength and dimensional stability. The method used for surface modification is UV-induced graft polymerization. It is a very simple and effective method, which does not necessitate any degassing and photo-sensitizer addition. Atomic force microscopic analysis (AFM), X-ray photoelectron spectroscopy analysis (XPS), friction test, zeta potential measurement and contact angle measurement were employed for characterization of modified polymer surface. The graft yield increased with the monomer concentration and the UV irradiation time. It is possible to obtain graft chains of different length by varying the monomer concentration and graft chains of different number densities by varying the UV irradiation time. By AFM observation the graft layers were exhibited inhomogeneo … More us cluster structure. When a fixed area of grafted surface was subjected to cyclic scanning by AFM tip with above 2.5 nN load, the deformation (tilting) of clusters was observed in water. It was reversible, recovering to the previous unperturbed shape as soon as loading tip had been taken away. On the surface of PET fabrics grafted with poly (methacrylic acid)(PMAAc), new peaks appeared in the C1s and O1s XPS assigned to the carboxylic group of PMAAc spectra. When they were previously subjected to reaction with Cu2+ ions, two peaks appeared in the Cu2p XPS spectrum on them. It indicated that the carboxylic groups of PMAAc chains were linked to Cu2+ ion through coordinate bonding. Then, this graft polymerization technique facilitates preparation of an antibacterial surface. Antibacterial activity and irritation of fabric treated polyethylenimine were evaluated with two antibacterial tests and skin model, respectively. This fabric showed excellent antibacterial activity, its durability for washing, and negative irritation. Less

我研究了聚对苯二甲酸乙二酯（PET）的表面改性，以增加几种新的功能，如舒适的感觉和抗菌性能，而不损失优异的机械性能，如强度和尺寸稳定性。用于表面改性的方法是UV诱导的接枝聚合。这是一种非常简单和有效的方法，它不需要任何脱气和光敏剂的添加。采用原子力显微镜（AFM）、X射线光电子能谱（XPS）、摩擦测试、zeta电位和接触角等测试手段对改性后的聚合物表面进行了表征。接枝率随单体浓度和紫外光照射时间的增加而增加。通过改变单体浓度可以获得不同长度的接枝链，通过改变紫外照射时间可以获得不同数量密度的接枝链。通过AFM观察，接枝层呈现出连续性， ...更多信息 美国集群结构。当接枝表面的固定区域进行循环扫描的AFM针尖与以上2.5 nN的负载，观察到在水中的变形（倾斜）的集群。这是可逆的，一旦取下加载头端，即可恢复到先前未受干扰的形状。在PET织物表面接枝聚甲基丙烯酸（PMAAc）后，C1 s和O 1 s XPS谱中出现了新的峰，归属于PMAAc的羧基。当它们预先与Cu ~（2+）离子反应时，在它们的Cu ~（2+）XPS谱中出现两个峰。表明PMAAc分子链上的羧基与Cu ~（2+）离子通过配位键连接。然后，这种接枝聚合技术有助于抗菌表面的制备。采用两种抗菌试验和皮肤模型评价了聚乙烯亚胺整理织物的抗菌活性和刺激性。该织物显示出优异的抗菌活性、耐洗涤性和负刺激性。少
