description | [Image: see text] Herein, we report cellulose-based threads from Indian sacred Lotus (Nelumbo nucifera) of the Nymphaceae family embellished with MoS(2) nanosheets for its enhanced hydrophobic and antimicrobial properties. MoS(2) nanosheets synthesized by a coprecipitation method using sodium molybdate dihydrate (Na(2)MoO(4)·2H(2)O) and thioacetamide (CH(3)CSNH(2)) were used as a sourse for MoS(2) particle growth with cellulose threads extracted from lotus peduncles. The size, crystallinity, and morphology of pure and MoS(2)-coated fibers were studied using X-ray diffractometry (XRD) and scanning electron microscopy (SEM). the XRD pattern of pure lotus threads showed a semicrystalline nature, and the threads@MoS(2) composite showed more crystallinity than the pure threads. SEM depicts that pure lotus threads possess a smooth surface, and the MoS(2) nanosheets growth can be easily identified on the threads@MoS(2). Further, the presence of MoS(2) nanosheets on threads was confirmed with EDX elemental analysis. Antimicrobial studies with Escherichia coli and Candida albicans reveal that threads@MoS(2) have better resistance than its counterpart, i.e., pure threads. MoS(2) sheets play a predominant role in restricting the wicking capability of the pure threads due to their enhanced hydrophobic property. The water absorbency assay denotes the absorption rate of threads@MoS(2) to 80%, and threads@MoS(2) shows no penetration for the observed 60 min, thus confirming its wicking restriction. The contact angle for threads@MoS(2) is 128°, indicating its improved hydrophobicity. |
