Present innovation emphasizes the design and development of hybrid nanoarchitecture by using simple twostep chemical routes, namely, "dip and dry", for multiwalled carbon nanotubes (MWCNTs) followed by coating of molybdenum telluride (MoTe 2 ) nanopebbles using successive ionic layer adsorption and reaction (SILAR) to form a thin film onto flexible stainless steel (SS) substrate toward the fabrication of a symmetric solid-state and flexible supercapacitor device. The MWCNTs/MoTe 2 nanostructured composite exhibits strong synergy and materials mutualism between electric double-layer capacitive (EDLC) behaved MWCNTs and pseudocapacitive MoTe 2 leading to the enhanced supercapacitive performance. Interestingly, the formed unique nanoarchitecture offers an excellent charge-storing capability of 502 F/g as the specific capacitance at 2 mV/s in liquid configuration with excellent rate capability and cyclic stability. The formed flexible complete solid-state symmetric supercapacitor (FCSS-SC) device using two SS/MWCNTs/MoTe 2 electrodes with poly(vinyl alcohol)-lithium perchlorate (PVA-LiClO 4 ) gel electrolyte as a mediator has demonstrated an upgraded potential window resulting in superior capacitance and energy density. Additionally, mechanical flexibility, cyclic stability, and hands-on application by a glowing light-emitting diode (LED) can attract the value of the formed device toward the advanced energy storage meadow.

“…Hence, the presence of B [233][234][235] The presence of oxide components in the XPS spectra indicates that the surface of the MoTe2 is slightly oxidized due to its air-sensitive properties upon exposure to air. [236][237][238][239] The extracted atomic ratio of Mo to Te was 1:2.2, in good agreement to the ideal stoichiometry of MoTe2.…”

First and foremost, I would like to express my sincere gratitude to my thesis supervisor Prof. Edwin Hang Tong Teo for his continuous support on my research and postgraduate study over the past four years. He gave me insightful advices on research projects, taught me the essential skill in conducting and presenting research, and provided me with precious opportunities to work close with many outstanding members in our group. I would also like to thank the rest of my thesis advice committee: Prof. Ken Tye Yong and Prof. Qihua Xiong for their insightful comments and encouragement.

“…These results confirm that Formvar transfer preserves the chemical composition of 1T′-MoTe 2 . In contrast, the XPS spectra of 1T′-MoTe 2 after PMMA transfer exhibits not only strong peaks attributed to MoTe 2 but also new peaks assigned to MoO 3 (232.5 eV, 235.7 eV) and TeO 2 (576.5 eV, 586.9 eV) . The ratios of MoO 3 and TeO 2 are 23.9% and 31.5%, indicating that partial oxidation of 1T′-MoTe 2 occurs during PMMA transfer.…”

Even though avoiding air whenever possible during transfer, sensitive 2D materials inevitably degrade, since PMMA transfer involves water and reactive etchants.…”

Scalable and Versatile Transfer of Sensitive Two-dimensional Materials

Damage-free transfer of large-area two-dimensional (2D) materials is indispensable to unleash their full potentials in a wide range of electronic, photonic, and biochemical applications. However, the all-surface nature of 2D materials renders many of them vulnerable to surrounding environments, especially etchants and water involved during wet transfer process. Up to now, a scalable and damage-free transfer method for sensitive 2D materials is still lacking. Here, we report a general damage-free transfer method for sensitive 2D materials. The as-transferred 2D materials exhibit well-preserved structural integrity and unaltered physical properties. We further develop a facile TEM sample preparation technique that allows direct recycling of materials on TEM grids with high fidelity. This recycling technique provides an unprecedented opportunity to precisely relate structural characterization with physical/chemical/electrical probing for the same samples. This method can be readily generalized to diverse nanomaterials for large-area damage-free transfer and enables in-depth investigation of structure−property relationship.
