“…Different techniques have been used to process PVDF and its polymer/composites based in different strategies (Table 1) to obtain various morphologies including micropillars [21], particles [20,22], films [23][24][25] and fibers [15,[26][27][28][29][30][31] in order to better suit specific tissue engineering strategies. Further, it has been shown that substrates based on PVDF have different influence on cell adhesion, proliferation and differentiation [7] depending on their morphology.…”

Cell supports based on electroactive materials, that generate electrical signal variations as a response to mechanical deformations and vice-versa, are gaining increasing attention for tissue engineering applications. In particular, poly(vinylidene fluoride), PVDF, has been proven to be suitable for these applications in the form of films and two-dimensional membranes. In this work, several strategies have been implemented in order to develop PVDF three-dimensional scaffolds. Three processing methods, including solvent casting with particulate leaching and three-dimensional nylon, and freeze extraction with poly(vinyl alcohol) templates are presented in order to obtain three-dimensional scaffolds with different architectures and interconnected porosity. Further, it is shown that the scaffolds are in the electroactive β-phase and show a crystallinity degree of ~ 45%. Finally, quasi-static mechanical measurements showed that an increase of the porous size within the scaffold leads to a tensile strengths and the Young's modulus decrease, allowing tuning scaffold properties for specific tissues.

“…The growth rate of the average film (0.1 lm min À1 ) is relatively high in comparison to chemical vapor deposition (CVD; <0.05 lm min À1 ) or physical vapor deposition (PVD; <0.06 lm min À1 ) [1]. Electrospray deposition operates under ambient conditions, it can deposit many different chemical compounds, and it does not damage the substrate or the deposited material [2][3][4][5][6][7][8]. An important attribute of electrospray is its capability of 'vaporizing' polymer molecules; the basis of its success in electrospray assisted mass spectrometry.…”

“…Firstly, poly(vinylidene fluoride) film of 25 nm was prepared with a roughness of 14 nm [7]. It took 15 min for a 0.05 wt.% solution with a flow rate of 2 lL min À1 to produce the film, resulting in a deposition rate of 1.7 nm min À1 (1 lg min À1 ).…”

“…[12,13] For example, poly(methyl methacrylate) (PMMA)/ethyl acetate solution [14] forms particles of decreasing size with increasing voltage. Poly(vinylidene fluoride) (PVDF) [15] particles have been processed by electrospraying its N,N-dimethylformamide (DMF) solution. It was concluded that the droplet size is controlled by the conductivity and flow rate of the solution.…”

Electrospinning at relatively low polymer concentrations produces polymer particles rather than fibers. To study the relationship between solvent characteristics and particle morphologies, PMMA was electrospun from seven different solvents and PSVPh random copolymers were electrospun from solutions in MEK. High‐speed photography was used to visualize the particle‐formation process. Based on these studies, a qualitative relationship between the solvent properties and the electrospun particle morphologies is discussed. By tailoring the solution properties and electrospinning conditions, particles with different morphologies (porous polygonal particles, solid polygonal particles, hollow spheres, cups etc) can be produced.
