树枝状聚合物已被用作开发纺织品的抗微生物性能的载体。我们已经利用了大量的功能团存在于规则和高度支化的三维结构的树枝状聚合物。在这项研究中，聚（酰胺胺）（PAMAM）G-3树枝状大分子进行了修改，以提供抗菌性能。按照与文献中所建议的类似的程序，将具有伯胺端基的PAMAM（G3）转化为铵官能团。然后通过FTIR和C-13-NMR分析证实了改性。树枝状聚合物由于其球形形状和可调腔而具有独特的性质，这使得它们能够与各种离子和化合物形成络合物;并且还可以作为模板来制造金属纳米颗粒。形成AgNO 3-PAMAM（G3）复合物以及MesoSilver-PAMAM（G3）复合物，并通过紫外-可见分光光度计对这些修饰的树枝状聚合物进行表征以研究复合物的形成。将改性树枝状聚合物应用于棉/尼龙混纺织物。进行SEM和EDX分析以研究银纳米颗粒在织物上的分散。经处理的织物对金黄色葡萄球菌的抗微生物测试对于每种类型的改性树枝状聚合物表现出显著的杀菌活性。(C)2009 Wiley Periodicals，Inc.

Dendrimers have been used as a vehicle to develop the antimicrobial properties of textile fabrics. We have taken advantage of the large number of functional groups present in the regular and highly branched three-dimensional architecture of dendrimers. In this study, the poly(amidoamine) (PAMAM) G-3 dendrimer was modified to provide antimicrobial properties. Following a procedure similar to what is suggested in the literature, PAMAM (G3) with primary amine end groups was converted into ammonium functionalities. The modification was then confirmed by FTIR and C-13-NMR analysis. Dendrimers have unique properties owing to their globular shape and tunable cavities, this allows them to form complexes with a variety of ions and compounds; and also act as a template to fabricate metal nanoparticles. AgNO3-PAMAM (G3) complex as well as a MesoSilver-PAMAM (G3) complex were formed and these modified dendrimers were characterized by a UV-Visible spectrophotometer to study the complex formation. Modified dendrimers were applied to the Cotton/Nylon blend fabric. SEM and EDX analysis were performed to study the dispersion of silver nanoparticles onto the fabric. An antimicrobial test of the treated-fabric against Staphylococcus aureus exhibited significant biocidal activities for each type of modified-dendrimer. (C) 2009 Wiley Periodicals, Inc.
