“…Therefore, the solvent system and the processing parameters could be a novel method to generate such fibers. In earlier reports, nonporous buckled nanofibers were successfully prepared via electrospinning [2] and had shown potential applications in cardiac tissue engineering [20,21]. However the complexity in the electrospinning set-up poses a disadvantage in the easy production of such patterned nanofibers.…”

“…Nanofibers with porous structures have ultrahigh surface area, can serve potential applications in filtration, absorption, fuel cell, catalysis, tissue engineering, drug delivery [2] and as structural and inductive components in microand nano-electromechanical systems and electromagnetic systems [3]. Porous nanofibers have a broader range of application in comparison with hollow nanofibers.…”

“…A tilted glass slide was used as the collector and it was found that tilt angles greater than 45° did not result in helical fibers [142]. Helical light-emitting conjugated polymers in which the polymer molecular weight affects the loop size and corresponding color shift have also been fabricated using the electrospinning technique [143].…”

Abstract:Traditional electrospun nanofibers have a myriad of applications ranging from scaffolds for tissue engineering to components of biosensors and energy harvesting devices. The generally smooth one-dimensional structure of the fibers has stood as a limitation to several interesting novel applications. Control of fiber diameter, porosity and collector geometry will be briefly discussed, as will more traditional methods for controlling fiber morphology and fiber mat architecture. The remainder of the review will focus on new techniques to prepare hierarchically structured fibers. Fibers with hierarchical primary structures-including helical, buckled, and beads-on-a-string fibers, as well as fibers with secondary structures, such as nanopores, nanopillars, nanorods, and internally structured fibers and their applications-will be discussed. These new materials with helical/buckled morphology are expected to possess unique optical and mechanical properties with possible applications for negative refractive index materials, highly stretchable/high-tensile-strength materials, and components in microelectromechanical devices. Core-shell type fibers enable a much wider variety of materials to be electrospun and are expected to be widely applied in the sensing, drug delivery/controlled release fields, and in the encapsulation of live cells for biological applications. Materials with a hierarchical secondary structure are expected to provide new superhydrophobic and self-cleaning materials.

“…Recently, polymer nanofibres containing carbon nanotubes [8][9][10][11], clay [12,13], ceramics [14] and metals [15,16] have been fabricated by several research groups. At the same time, research on nanofibre assemblies explored various structures and methods, including aligned fibres [17][18][19][20], patterned fibres [21,22], and helical fibres [23]. In this report, we developed a general approach for the creation of polymer nanocomposites with alignment of CNTs.…”

Abstract.A facile way for alignment of carbon nanotubes in macroscopic polymer matrix was developed by combining electrospinning and in-situ polymerization. The approach is based on the formation of nanofibre scaffolds with wellaligned arrays, which is filled with carbon nanotubes (CNTs). CNTs will be well aligned in macroscopic polymer matrix when the aligned nanofibre scaffold containing CNTs has been incorporated into the poly(methyl methacrylate) (PMMA) matrix by in-situ polymerization. We demonstrate that this scaffold approach is broadly applicable and allows for the fabrication of nanocomposites with accurately aligned nanofillers. The results presented in this report show that the approach is ideal by using polyacrylonitrile (PAN) nanofibres as a scaffold of multiwalled carbon nanotubes (MWNTs), and PMMA as the macroscopic polymer matrix. The tensile strength (7.2 wt% MWNTs/PAN nanofibres loadings) reaches 48.61 MPa, 87% higher than that pure PMMA, and the tensile modulus is increased by 175%.
