An effective utilization of MXene and its effect on electromagnetic interference shielding: flexible, free-standing and thermally conductive composite from MXene–PAT–poly(p-aminophenol)–polyaniline co-polymer

“…3a and 5a). 14,[24][25][26][27]50,56,57 Moreover, peaks at 25.3 and 25.7 agree with XPS result ( Fig. 7a-d .…”

Fabrication of Nonwetting Flexible Free‐Standing MXene‐Carbon Fabric for Electromagnetic Shielding in S‐Band Region

“…The O1s peaks at 529.5 eV were assigned to TiO (TiO 2 ), whereas 531.1, 532.2, and 533.7 eV were allotted to TiC(OH) x , Al 2 O 3, and H 2 O, respectively (Figure (e)). Moreover, the presence of TiO 2 confirmed that slight oxidation of the surface . Hence, MXene formed with the formula of Ti 3 C 2 (F,OH).…”

“…The 2θ peak at 7.14° (002) signified the characteristic peak of MXene, while at 14.36°, 19.12°, 28.98°, 38.86°, and 40.9° 2θ angles confirmed the presence of crystalline MXene . The disappearance peak of Ti 3 AlC 2 at 38.99° generated broad peaks of Ti 3 C 2 T x at 38.85° and 38.95° confirmed the eradication of Al and introduction of surface functionalities . In addition, the intense peaks at 9.5° of Ti 3 C 2 T x were considered as the corresponding MAX stack structure remains after the etching process (Figure (k)).…”

“…In addition, MXene‐coated fabric exhibited some sharp peaks revealed the presence of crystalline structure. The Ti 3 AlC 2 displayed sharp 2θ peaks at 9.54°, 19.53°, 34°, 35.1°, 36.8°, 38.99°, 41.76°, 42.54°, 48.48°, 52.36°, 56.5°, 60.16°, 52.36°, 64.98°, 70.34°, 74.02° represented the corresponding reflection planes those were (002), (004), (101), (102), (103), (008), (104), (105), (107), (108), (109), (110), (1011), (1011), (1012), and (118), respectively . The complete removal of 104 peak indicated that destruction of Ti 3 AlC 2 and introduction of surface functional groups (Figure (b)).…”

Study on Combined Optical and Electrochemical Analysis Using Indium‐tin‐oxide‐coated Optical Fiber Sensor

“…The explanation of this phenomenon is complex due to many factors affecting the EC process. The capacitance of the electrode which depends on the electrolyte properties, i. e., its pH, type of cation and anion species, and salt concentrations, should be mainly taken into consideration . The electrolyte concentration has a significant influence on the mass transport of the analyte according to the Nerst‐Planck equation.…”
