“…For adoption in a practical scenario, an FED eld emitter must possess the following traits: low turn-on eld, high current density and stable emission etc. Among these synthesized nanostructures, eld emission properties of CuPc nanobres and nanowires with turn-on elds 13.6 V mm À1 and 8.1 V mm À1 was reported by Suen et al and Tong et al, 11,12 respectively. [2][3][4][5] Onedimensional (1D) semiconductor nanostructures are well known to be promising in this regard due to their large aspect ratio.…”

“…In comparison to its peers, FED has advantages such as higher brightness, lower power consumption, larger color gamut and shorter response time. [7][8][9][10][11][12][13][14][15] Being highly resistant to chemical and thermal degradation, copper phthalocyanine CuPc is a superior candidate as a eld emitter among the organic semiconductors. Inspired by this speculated array of exciting features, several groups have focused their attentions to design excellent cold cathode emitting materials.…”

In the present work, we report fabrication and field emission responses of 3D copper phthalocyanine (CuPc) nanotip arrays synthesized over nanotube walls by facile plasma treatment. Significant field emission enhancement is confirmed for a nanotip-nanotube hybrid system (turn-on field 4.2 V mm À1 @10 mA cm À2 ) as compared to pristine CuPc nanotubes (turn-on field 6.8 V mm À1 @10 mA cm À2 ). Root of the observed enhanced cold cathode emission performances is further probed by a finite element method based simulation protocol that computed local electric field distribution for a single tube without and with plasma etching in a manner parallel to the experimental setup. Our obtained results strongly suggest that CuPc nanotip-nanotube hybrid nanostructures are a major potential candidate as field emitters for vacuum nanoelectronics and cold cathode based emission display applications.

“…Making use of the aromatic heterocyclic molecules with high symmetry, planarity and 18 π-electron delocalized systems, special architectures (microsphere, nanofiber, nanowire and nanoflower) have been successfully fabricated by self-assembly of CuPc [2][3][4], which can be served as the building block for the fabrication of solar cells, fuel cells, optical-limiting material, gas sensors and field-effect transistors [5][6][7].…”

Abstract.A novel kind of selectively functionalized-graphene reinforced copper phthalocyanine (RGO-O-CuPc) nanocomposites was successfully fabricated through a facile and effective three-step method, involving preferential surficial modification and reduction of graphene oxide (GO) sheets, and followed by incorporating with CuPc via in situ polymerization. The results of SEM, AFM, XPS, FTIR, XRD and UV-vis confirmed that GO was effectively surficial functionalized by a ring-open covalent reaction between amino in 3-aminophenoxyphthalonitrile (3-APN) and epoxy groups on the GO sheets, and partly reduced back to graphene under solvothermal conditions. And the RGO-O-CuPc was successfully fabricated by self-assembling of CuPc molecule on graphene sheets via in situ polymerization. As a consequence, the selective surface functionalization and solvothermal reduction of GO facilitated the improvement in the dielectric constant and AC conductivity, and the decrease in the dielectric loss of the graphene/CuPc nanocomposites.

“…One such area includes nanofibre-based technology, which has grown exponentially considering the potential opportunities provided by nanofibres. The technologies usually employed for the production of nanofibres are the template method (Zhang & Liu 2008;Dougherty & Liang 2009) et al 2005), phase separation (Zhang & Hsieh 2008), self-assembly (Suen et al 2006;Mao et al 2008) and electrospinning (Vohra et al 2011;Zhang et al 2011). From the above-mentioned technologies, electrospinning has attracted tremendous interest due to its simplicity, low cost and versatility in design with potential for industrial-scale processing of continuous nanofibres.…”

New correlation formulae for the straight section of the electrospun jet from a polymer drop

An electrospun polymer jet issued from a Taylor cone follows a straight-line motion before experiencing electrical bending instability resulting in curling and spiralling of the jet in three-dimensional space. Experiments are performed to characterize the fluid dynamics of an electrospun polymer jet. Appropriate image processing is performed to systematically analyse flow regimes of the electrospun jet. These regimes include Taylor cone formation/jet initiation and the straight section of the jet. Dimensional analysis was performed to identify the salient dimensionless parameters, which govern the electrospun jet characteristics. Three new correlation formulae were obtained to characterize the dimensionless jet diameter at the apex of the Taylor cone (d = 1.03Q 0.44 ), the dimensionless jet diameter at different locations along the jet's straight section (dz 1/4 = 1.09Q 1/2 ), as well as the length of the straight section of the jet (Z in = 86Q 0.42 ). These correlation formulae are valid for the analysed range of dimensionless flow rates (2.6×10 −4
