“…The main absorption band peak at 3,279 cm −1 for the NCFs was lower than that of the matrix, noticing that the consumption of hydroxyl (−OH) functional groups was reduced the Cu +2 ions into CuNPs. The same observation was reported by earlier workers (Amara et al, 2019) during the biosynthesis of CuNPs on NCFs using red sander powder extract as a reducing agent.…”

“…Nanocomposites are gaining importance in our daily life as an emerging field of nanotechnology, which utilizes in pharmaceutical, textile, industrial, biological, and biomedical applications (Jia et al, 2012;Zare and Shabani, 2016). In medicine, metal nanoparticles (MNPs), such as copper, silver, titanium, gold, and platinum, are showing good biological properties (Dizaj et al, 2014;Nasrabadi et al, 2016;Palza et al, 2015;Zain et al, 2014). In specific, copper nanoparticles (CuNPs) were proved to have potential antibacterial, antifungal, and mechanical properties (Bagchi et al, 2013;Viet et al, 2016).…”

Nanomaterials are finding the diversity of application at the leading edge in emerging field of nanotechnology. Copper nanoparticles (CuNPs) were in situ generated on the surface of cotton fabrics, using Achyranthes aspera leaf extract by environmentally benign green synthesis. The structural and morphological properties of synthesized nanocomposite cotton fabrics (NCFs) were characterized by different spectral studies such as Fourier-transformation infrared (FTIR), scanning electron microscopy (SEM) coupled with energy-dispersive X-ray primary and derivative thermogravimetric (TG-DTG), differential scanning calorimetry (DSC), and X-ray diffractometer (XRD). The molecular functionalities of hydroxyl groups in polyphenols of A. aspera leaf extract were identified from FTIR absorption spectrum, and they are responsible for the bioreduction of Cu +2 into Cu 0 for the formation of CuNPs. The average size of the formed CuNPs from SEM studies was found to be 95 nm. The formed CuNPs were exhibited Face centered cubic (FCC) crystalline structure, and it was confirmed by XRD studies. TG-DTG analysis publicized the thermal stability of NCFs. The tensile strength of NCFs was higher than normal cotton fabrics. These NCFs exhibited good antibacterial properties which considered for making aprons and wound dressing materials in medicine and for packing materials.

“…The researchers are now employing in situ method for the generation of MNPs and MONPs in polymer matrices to overcome agglomeration of nanoparticles which leads to low quality properties to the resulting nanocomposites [18]. In current times, in situ generation method was employed for the generation of nanocomposites with silver and copper nanoparticles [19,20]. Recently, the scientists are utilizing biogenic plant species parts as bio reductants and stabilizing agents for the synthesis of nanocomposites for the production of MNPs and MONPs using in situ generation method [21][22][23].…”

A simple, low cost and environmentally bioreduction method was adopted to in situ generate silver nanoparticles (AgNPs) on the surface of cellulose cotton fabrics utilizing Tinospora cordifolia leaf extract as reducing agent. The bio generation of AgNPs in nanocomposite cellulose cotton fabrics (NCCFs) was confirmed by Fourier Transform Infrared spectroscopy, Scanning Electron Microscopy along with Energy Dispersive X-ray (EDX) spectroscopy, X-ray Diffraction (XRD), primary and derivative thermogravimetric (TG and DTG) analysis and Differential Scanning Calorimetry (DSC). The generated AgNPs in NCCFs were found to be spherical in shape with an average size of 90 nm. The presence of silver element was revealed by EDX spectra with an energy absorption peak at 3 keV. The bio synthesized AgNPs were found to be crystalline in nature from XRD. The bio generated AgNPs in NCCFs were found to be stable up to 399 °C as confirmed by DTG and DSC analysis. These NCCFs also exhibited good mechanical properties. Further, these also exhibited good antibacterial activity against pathogenic disease producing Gram positive (G +ve) and Gram negative (G −ve) bacteria. Basing on these properties, the prepared NCCFs can be considered for medical applications such as hospital bed materials, aprons etc. and also for packing applications.

The method of in situ generation was employed to produce binary silver and copper bimetallic nanocomposites (BNCFs) using lesser emission pollutant biological plant species i.e., Tinospora cordifolia (TC) leaf broth as reducing agent. The generated BNCFs were confirmed by different spectrophotometric studies i.e. Fourier Transform Infrared (FTIR), Scanning Electron Microscope (SEM) along with Energy Dispersive X-ray (EDX), X-ray Diffractometer (XRD), Primary and Secondary thermogravimetric (TG & DTG) analysis and Differential Scanning Calorimetry (DSC). The bio synthesized nanocomposite cotton fabrics (NCFs) were found to be spherical in shape and with an average size of 80nm from SEM analysis. The elements silver and copper were confirmed by observing peaks at 3keV and 1keV, respectively, from EDX spectra. The XRD studies revealed the crystalline nature of BNCFs. TG and DTG analysis explained the catalytic activity of silver and copper with lesser thermal stability. The BNCFs showed good tensile properties, using universal testing machine. The BNCFs also exhibited good antibacterial activity against disease producing G+ve and G-Ve bacteria. The BNCFs mat be considered to make bandage cloths, napkins etc., in the medical field.
