Enhanced Functional Properties of ZrO2/SiO2 Hybrid Nanosol Coated Cotton Fabrics

Abstract

In this present investigation, the colloidal silica and nano ZrO2 embedded silica solution were prepared using sol-gel method followed by the sonication process. The particle size was measured for the prepared silica sol with and without ZrO2 nanoparticles. The prepared nanoparticles were coated on the cotton fabric through pad dry method. The phase and functional group analysis of the cotton fabrics after coating reveals the presence of metal oxides on the surface. The surface morphology of the coated fabrics analysed using SEM shows that the nanoparticles were in spherical morphology with slight agglomerations. The element analysis confirms the presence of silica (SiO2) and ZrO2/SiO2 nanoparticles along with cellulose on the surface. The washing durability of the coated fabrics after 5th and 10th wash indicates that the nanoparticles were strongly adhered on the fabric surface. The burning performance of coated fabrics is in the order of ZrO2/SiO2 (19.5 s) > SiO2 (11.3 s) before and after wash; UV resistance of fabric was in the order of ZrO2/SiO2 > SiO2 > uncoated fabric. Cotton fabrics coated with ZrO2/SiO2 particles show better UV and flammability protection for textile applications.

Development of functional hybrid cotton fabrics by coating with SiO2and ZrO2/SiO2composites

“…This is due to the removal of nanoparticles by the washing process, which is clearly shown in Figs. 3b and c. These observations are similar to those reported earlier [12]. The obtained results are further compared with coated and uncoated fabrics before and after washes.…”

Multifunctional cellulose-containing fabrics using modified finishing formulations

“…The enhancements in the imparted functionalities, gained through modifying the nishing formulation, reect the positive impacts of the added MO-NPs on the surface morphology, location and distribution of crosslinks, creation of antibacterial active sites on the nish/ fabric matrix and thermal stability and re-retardant functionality of the treated substrates, thereby improving UVprotection, easy-care, antibacterial activity and increasing the ammability time, respectively. 47 The enhancement in the ame retardant attributes of the treated substrates is governed by the type of immobilized MO-NPs, and their thermal stability, synergetic effects, ability to act as a barrier to heat and mass transfer, capability to change the degradation pathway of the textile polymer and ability to hinder the mobility of textile polymer chains and/or to absorb the generated active species, 48 keeping other parameters xed. The degree of xation of both the phosphorous sulfur and nitrogen components to the nish/fabric matrix cannot be rolled out.…”

Larvicidal, super hydrophobic and antibacterial properties of herbal nanoparticles from Acalypha indica for biomedical applications

“…A similar observation was reported in our previous study on obtaining the herbal nanoparticles from Tridax procumbens under different milling periods. 26 The TEM (Fig. 7) image of the prepared AINPs conrms the spherical nature with high dispersion.…”

“…The XRD pattern of AINPs is shown in Fig. 2, which conrms the absence of diffraction peaks i.e., amorphous nature, except for the observed broad band at 2q values (20)(21)(22)(23)(24)(25)(26)(27)(28)(29)(30). Generally, the amorphous nature of the particles is non-toxic to living organisms and hence, amorphous herbal nanoparticles enhance the biocompatibility for clinical applications.…”

“…23,24 The recent studies on the selfcleaning, water repellent, high durability, antibacterial and UV protection properties, etc., of the herbal nanoparticles coated textiles strongly suggest their application in medicine. 25,26 In the present study, we focus on the development of bio medically important herbal nanoparticles using the green synthesis method. The herbal nanoparticles are prepared from A. indica leaves using a ball mill without the addition of chemicals for aggregation and template shaping.…”
