Recently, nano finishing of textiles is increasingly attracted many researchers to create new features on the products. Here a new fabric is introduced through simultaneous aminolysis and hydrolysis of polyester along with in-situ sonosynthesis of hedgehog shaped nickel nanoparticles on the fabric with magnetic properties. To do this, nickel sulfate, hydrazine hydrate, sodium hydroxide and polyvinylpyrrolidone (PVP) were used as a precursor, reducing agent, alkali and stabilizer respectively. Nickel sulfate was reduced to nickel nanoparticles with hydrazine hydrate at the adjusted pH with NaOH in the presence of PVP at 75 °C for 2 h. The polyester fabric was aminolyzed and hydrolyzed produced various functional groups on the fabric surface assisted nucleation and stabilization of nickel nanoparticles. The morphology, crystal phase, magnetic properties and chemical structure of the treated fabrics were characterized by field emission scanning electron microscopy (FESEM), X-ray diffraction (XRD), vibrating sample magnetometry (VSM), and energy dispersive X-ray spectroscopy (EDX). The optimized sample treated with 3.19 (mL) hydrazine hydrate, 3.99 (mL) sodium hydroxide and 0.41 (g) nickel sulfate showed reasonable saturation magnetization value of 4.5 emu g-1. The treated fabrics showed no antibacterial and antifungal behavior indicating the safety of the products.

刺猬样镍纳米粒子在聚酯织物上的原位超声合成产生磁性

最近,纺织品的纳米整理越来越吸引着许多研究人员在产品上创建新功能。在此,通过同时氨解和聚酯水解以及原位引入一种新的织物刺猬形状的镍纳米粒子在织物上的超声合成,具有磁性。为此,分别使用硫酸镍,水合肼,氢氧化钠和聚乙烯吡咯烷酮(PVP)作为前体,还原剂,碱和稳定剂。在PVP的存在下,在75°C的条件下,在NaOH调节的pH值下,用氢氧化钠将硫酸镍与水合肼还原为镍纳米粒子。聚酯织物被氨解和水解,从而在织物表面上产生了各种官能团,从而有助于镍纳米颗粒的形核和稳定。通过场发射扫描电子显微镜(FESEM),X射线衍射(XRD),振动样品磁强法(VSM)表征了经过处理的织物的形态,晶相,磁性和化学结构。和能量色散X射线光谱仪(EDX)。经3.19(mL)水合肼,3.99(mL)氢氧化钠和0.41(g)硫酸镍处理的优化样品显示了4.5 emu g的合理饱和磁化值-1。经处理的织物没有显示出抗菌和抗真菌的特性,表明产品的安全性。
