“…The investigation of literature shows that the mechanical properties of electrospun PCL nanofibers improve at the presence of different nanoparticles [7,8,11,12]. Among different nanoparticles, graphene and its derivatives could present a higher improvement in mechanical properties due to their higher surface area than other nanoparticles [13][14][15][16][17][18]. However there are few studies on the mechanical properties of electrospun PCL fibers in the presence of different amounts of GO and RGO.…”

“…[33,43] However, compared to nanotubes, relatively little work has been done to investigate the potential of 2D nanosheets as fillers in composite fibres. A number of papers have used chemically modified graphene (graphene oxide, GO) as a filler in composite fibres, [44][45][46][47][48][49][50][51][52][53] while other groups have studied graphene-oxide-only fibres. [54][55][56][57][58][59][60][61][62][63][64][65] However, while GO nanosheets may show good polymernanosheet stress transfer, they are not ideal reinforcements as they have impaired mechanical properties due to their high defect content (i.e.…”

Here we describe using nanosheets of both graphene and boron nitride, produced by liquid phase exfoliation, as fillers in composite fibres. The fibres were prepared by coagulation spinning using polyvinylalcohol as a matrix. We obtained good quality fibres with diameter and nanosheet volume fraction which could be controlled via the ratio of nanosheet to polymer injection rates. The mechanical stiffness (modulus, Y) and strength, σB, increased relatively slowly with volume fraction (dY/dVf 160 GPa and dσB/dVf 0.8 GPa). However, both stiffness and strength continued increasing with nanosheet content to loading levels of ~20vol%, after which the properties fell off. Such relatively high loading levels result in impressive mechanical properties with stiffness and strength of up to 30 GPa and 260 MPa observed. In addition, we found the graphene-filled fibres to be electrically conducting with conductivities of up to 3 S/m.

“…He et al injected sodium alginate/graphene oxide (GO) into a bath of CaCl 2 . 29 The maximum tensile strength and Young's modulus were increased by several fold at 4 wt% GO loading (from 0.32 and 1.9 to 0.62 and 4.3 GPa, respectively). Fibers were seeded with rabbit cartilage cells and showed a good attachment and proliferation.…”

Engineering tissues and organs for implantation in the human body or research require the fabrication of constructs that reproduce a physiological environment. Moreover, the construction of complex and sizable three-dimensional tissues requires a precise control over cell distribution and an effective vasculature network to supply oxygen and nutrients, and remove waste. Fiber-based tissue engineering that forms 3D structures using fibers can address many of these challenges, but depends on the quality of the fibers. Recent progresses in microtechnologies have enabled researchers to fabricate biocompatible fibers with advanced biochemical and physical properties, including cell-laden fibers that are pre-seeded with cells. In this chapter, we discuss fiber fabrication techniques including co-axial flow spinning, wetspinning, meltspinning, and electrospinning, which have leveraged microtechnologies to improve their performance. We compare the properties of the fibers fabricated with these methods and discuss their strengths and weaknesses in the context of tissue engineering.
