“…During this process, h-BN powder (UT and PT) was sonicated in DMF for 30 min to obtain excellent dispersion discussed in mutual support of literature. [32][33][34] Further h-BN solution was slowly added into solute C (for 2 h at 60 C at 600 rpm). Finally, PVDF/ PSF/h-BN nano blends solution was poured into a glass petri dish and dried at 60 C temperature in a hot-air oven overnight to obtain solvent free films.…”

In the present era electrostatic dissipation (ESD) property is crucial for packaged electronic device to protect from humidity over long duration. It was important to control the ESD for better integrated packaged electronic gadgets. Polymer blends and composites were modified with nano fillers as a promising area for ESD applications. In the present investigation, polyvinylidene fluoride (PVDF)/polysulfone (PSF) was modified by untreated (UT) and air plasma treated (PT) hexagonal boron nitride (h‐BN) by solution dispersion method. Spherulitic morphology of nano blends was foreseen through scanning electron microscopy. Surface topography was investigated by atomic force microscopy. Surface roughness was decreased due to plasma exposure. Phonon vibrations and Raman active mode of nano blends were confirmed by Raman spectroscopy mutually supporting ESD phenomenon. Increased electrical conductivity and semicircular impedance pattern of modified blends reveals an excellent ESD property disclosed by impedance spectroscopy. Moderate increased surface energy and decreased relative contact angle of modified blends may be due to the incorporation of polar groups during plasma exposure was confirmed by surface goniometer. Mechanical properties of nano blends were evaluated by universal testing machine. Increased 10–27% tensile strength and 34–55% Young's modulus of plasma treated admix composition. Softness of polymer nano blends was increased (20%) due to excellent interaction of filler and polymer host system were tested by Shore “A” durometer. Increased glass transition temperature (Tg = 16 and 30°C as function of treatment time) in view of thermal stability of modified nano blends were analyzed by thermogravimetric technique. Hence the PT h‐BN dispersed PVDF/PSF emerging polymer nano blends would be a choice for the new development for electrostatic dissipation applications.

“…The quality of the nanotubes is increased by adding functional moiety on the surface of the nanotube in the container [22]. Some of the factors affecting the dispersion of nanotubes are the size of the pebbles, rotational speed, milling time, and amount of nanotube added [23]. As a result, nanotubes with less than 100 nm can be obtained by the grinding process.…”

Nanomaterials are endowed with unique features and essential properties suitable for employing in the field of nanomedicine. The nanomaterials can be classified as 0D, 1D, 2D, and 3D based on their dimensions. The nanomaterials can be malleable and ductile and they can be drawn into wires and sheets. Examples of nanomaterials are quantum dots (0D), nanorods, nanowires (1D), nanosheets (2D), and nanocubes (3D). These nanomaterials can be synthesized using top-down and bottom-up approaches. The achievements of 0D and 1D nanomaterials are used to detect trace heavy metal (e.g., Pb2+) and have higher sensitivity with the order of five as compared to conventional sensors. The achievements of 2D and 3D nanomaterials are used as diagnostic and therapeutic agents with multifunctional ability in imaging systems such as PET, SPECT, etc. These imaging modalities can be used to track the drug in living tissues. This review comprises the state-of-the-art of the different dimensions of the nanomaterials employed in theranostics. The nanomaterials with different dimensions have unique physicochemical properties that can be utilized for therapy and diagnosis. The multifunctional ability of the nanomaterials can have a distinct advantage that is used in the field of theranostics. Different dimensions of the nanomaterials would have more scope in the field of nanomedicine.

“…The fabrication steps of the gFPCs via the matrix modification method are demonstrated in Figure 8 . A certain amount of graphene (wt.%) is mixed with the polymer resin by a wide variety of mixing techniques including shear mixing either mechanical or magnetic [ 143 , 144 ], extrusion [ 145 ], rolling (calendaring), or ball milling [ 146 ], and ultrasonication [ 147 ]. These techniques can also be applied together to ensure the proper dispersion of the nanomaterials resulting in the ultimate desired properties of the composite structures [ 148 ].…”

Graphene-based materials in the form of fibres, fabrics, films, and composite materials are the most widely investigated research domains because of their remarkable physicochemical and thermomechanical properties. In this era of scientific advancement, graphene has built the foundation of a new horizon of possibilities and received tremendous research focus in several application areas such as aerospace, energy, transportation, healthcare, agriculture, wastewater management, and wearable technology. Although graphene has been found to provide exceptional results in every application field, a massive proportion of research is still underway to configure required parameters to ensure the best possible outcomes from graphene-based materials. Until now, several review articles have been published to summarise the excellence of graphene and its derivatives, which focused mainly on a single application area of graphene. However, no single review is found to comprehensively study most used fabrication processes of graphene-based materials including their diversified and potential application areas. To address this genuine gap and ensure wider support for the upcoming research and investigations of this excellent material, this review aims to provide a snapshot of most used fabrication methods of graphene-based materials in the form of pure and composite fibres, graphene-based composite materials conjugated with polymers, and fibres. This study also provides a clear perspective of large-scale production feasibility and application areas of graphene-based materials in all forms.
