The development of composite materials consisting of metal nanoparticles embedded in macromolecular compounds, obtained via in-situ reduction process has attracted research interest. Silver nanoparticles (AgNPs) have been synthesized by a one-step method at 25 °C, that involves photo-reduction of AgNO₃ dissolved in a solution of oligomers which promoted Ag${}^{\circ }$ generation. These highly functionalized oligomers, obtained from ethylene glycol diglycidyl ether (EGDE), imidazole and methacrylic acid, were tested as reagents in photo-reduction/NP stabilization. Their functional groups acted as ligands on coordinating ${\mathrm{Ag}}^{+}$ and then stabilizing AgNPs, being particularly involved ether function of EGDE, according to DLS and FT-IR evidence. These organic macromolecules strongly promoted the adherence of AgNP-oligomers structures to polystyrene substrate. The composite materials were further characterized by UV–visible spectroscopy, electrochemical methods, SEM and TEM. The antimicrobial activity of the polystyrene surface modified with AgNP-oligomers was studied, concluding that it had biocidal activity against Gram positive and Gram negative bacteria.

通过原位还原过程获得的由嵌入大分子化合物中的金属纳米颗粒组成的复合材料的开发引起了研究兴趣。银纳米颗粒（AgNPs）已通过一步法在25°C下合成，该过程涉及光还原溶解在促进Ag的低聚物溶液中的AgNO ₃${}^{\circ }$代。从乙二醇二缩水甘油醚（EGDE），咪唑和甲基丙烯酸获得的这些高度官能化的低聚物已作为光还原/ NP稳定剂进行了测试。它们的官能团充当配体${\mathrm{银}}^{+}$然后根据DLS和FT-IR证据，稳定AgNP，尤其是涉及EGDE的醚功能。这些有机大分子强烈促进了AgNP-低聚物结构对聚苯乙烯基质的粘附。通过紫外可见光谱，电化学方法，SEM和TEM对复合材料进行了进一步表征。研究了用AgNP-低聚物改性的聚苯乙烯表面的抗菌活性，认为它对革兰氏阳性和革兰氏阴性细菌具有杀生物活性。
