The cost-effective spray coated composite was successfully synthesis and characterized by scanning electron microscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, and X-ray diffraction techniques. The one step synthetic strategy was used for the synthesis of nanoplates that have a crystalline nature. The composites are amorphous and hydrophobic with micron thickness (<400 m). The maximum contact angle showed by composite is 132.65° and have wetting energy of −49.32 mN m−1, spreading coefficient −122.12 mN m−1, and work of adhesion 23.48 mN m−1. The minimum thickness of synthesized nanoplate is 3 nm while the maximum sheet resistance, resistivity, and electrical conductivity of the composites are 11.890 ohm sq−1, 0.4399 Ω.cm−1, and 8.967 S.cm−1, respectively. The cobalt nanoplate coated non-woven carbon fabric (CoFC) possesses excellent sheet resistance, hydrophobic nature, and EMI shielding efficiency of 99.99964%. The composite can block above 99.9913% of incident radiation (X band). Hence, the composite can be utilized in application areas such as medical clothes, mobile phones, automobiles, aerospace, and military equipment.

2D titanium carbide (Ti 3 C 2 T x ) MXene films, with their well-defined microstructures and chemical functionality, provide a macroscale use of nano-sized Ti 3 C 2 T x flakes. Ti 3 C 2 T x films have attractive physicochemical properties favorable for device design, such as high electrical conductivity (up to 20 000 S cm -1 ), impressive volumetric capacitance (1500 F cm -3 ), strong in-plane mechanical strength (up to 570 MPa), and a high degree of flexibility. Here, the appealing features of Ti 3 C 2 T x -based films enabled by the layer-to-layer arrangement of nanosheets are reviewed. We devote attention to the key strategies for actualizing desirable characteristics in Ti 3 C 2 T x -based functional films, such as high and tunable electrical conductivity, outstanding mechanical properties, enhanced oxidation-resistance and shelf life, hydrophilicity/hydrophobicity, adjustable porosity, and convenient processability. This review further discusses fundamental aspects and advances in the applications of Ti 3 C 2 T x -based films with a focus on illuminating the relationship between the structural features and the resulting performances for target applications. Finally, the challenges and opportunities in terms of future research, development, and applications of Ti 3 C 2 T x -based films are suggested. A comprehensive understanding of these competitive features and challenges shall provide guidelines and inspiration for the further development of Ti 3 C 2 T x -based functional films, and contribute to the advances in MXene technology.
