Clean low-temperature in situ synthesis of durable silver nanoparticles along with aminolysis of polyester fabric using dopamine hydrochloride

摘要

In this study, aminolysis of polyester fabric was carried out along with in situ synthesis of silver nanoparticles in a single-step processing at room temperature producing fabric with antistatic through hydrophilic properties with enhanced tensile strength. AgNO3 was used as a source of silver in the presence of dopamine hydrochloride as a friendly reducing and stabilizing agent that played a prominent role in the synthesis and adsorption of Ag nanoparticles on the polyester fabric. Formation of a polydopamine layer on the fabric surface leads to higher wettability, antistatic property, and strong linkage of nanoparticles on polyester fabric. XRD pattern confirmed the presence of Ag nanoparticles with crystal size of 34.4 nm on the fabric surface, and FESEM images showed the distribution of nanoparticles on the fiber surfaces with an average size of 64 nm. A new hydrophilic and antistatic polyester fabric with higher tensile strength and reasonable durability was obtained through in situ synthesis of Ag nanoparticles at room condition using silver nitrate and dopamine as a desirable fabric for various medical and industrial applications.
