Fabrication of MXene (Ti2C3Tx) based conducting polymer materials and their applications as anticancer and metal ions removal from wastewater

Abstract

A new types of 2D MXene based conducting polymer materials was constructed by in-situ polymerization techniques. In addition, the MXene (Ti3C2Tx) was synthesized with the combination of Ti3AlC2 and HF, after successful preparation of Ti3C2Tx then, their surface was functionalized with glycidyl methacrylate (GMA) and formed the Ti3C2Tx@PGMA. Further, the Ti3C2Tx@PGMA is combined with polyaniline (PANI) to form conducting polymer grafted thin film nanosheets named Ti3C2Tx@PGMA/PANI with a thickness in micrometer size through the grafting method. The prepared materials were characterized by SEM, FTIR, XRD, XPS, and EDX techniques. To check the performance of materials, the in-vitro anticancer activities were performed with laser and without laser. Ti3C2Tx@PGMA/PANI-treated cancer cells exposed to an 808 nm laser (0.48 W cm2, 10 min) showed a significant anticancer impact, and practically all anticancer cells were destroyed. The MTT findings demonstrating the effective in vitro anticancer impact of Ti3C2Tx@PGMA/PANI were supported by the Calcein AM/PI double staining examination. Additionally, an adsorption investigation was conducted using the metals Cr3+ and pb2+, and the maximum adsorption reached 303.3 and 201.6 mg/g, correspondingly. The recovering study was also conducted, and Ti3C2Tx@PGMA/PANI nanosheets can be easily recycled and regenerated after ten successful recovering recycle. It is anticipated that the developed process for making the MXene and conducting polymer-based Ti3C2Tx@PGMA/PANI nanosheets would be usable for various other advanced applications.
