“…The latter surfaces are often strongly hydrophobic, featuring the well-known water repellent Lotus effect [17]. The amount of different self-ordered surface structures renders various ways of particular surface functionalization possible-as demonstrated in applications for surface colorization [18], the reduction of friction and wear [19], the control of cell or biofilm growths [20,21], or the promotion of protein adsorption [22].…”

“…One of the most efficient ways to increase the surface area of composites consists on the production of microfibers by electrospinning [22], in which the modification of the processing parameters lead to variations in electrospun fiber morphology, orientation and diameter [23]. In this way, electrospinning can produce fibers and membranes that are able to mimic extracellular matrix (ECM) of biological tissues [24], being increasingly important in the development of scaffolds for a variety of biomedical applications [25,26] by allowing tailoring cell functions, adhesion and proliferation [27] through modulation of surface electrostatic charge [28], wettability [29], mechanical properties [30] and topography. The introduction of fillers in fibers can also contribute to modify bioactivity and even biocompatibility suppression can occur.…”

Effect of filler content on morphology and physical–chemical characteristics of poly(vinylidene fluoride)/NaY zeolite-filled membranes

Poly(vinylidene fluoride) electrospun membranes have been prepared with different NaY zeolite contents up to 32%wt. Inclusion of zeolites induces an increase of average fiber size from ~200 nm in the pure polymer up to ~500 nm in the composite with 16%wt zeolite content. For higher filler contents, a wider distribution of fibers occurs leading to a broader size distributions between the previous fiber size values.Hydrophobicity of the membranes increases from ~115º water contact angle to ~128º with the addition of the filler and is independent on filler content, indicating a wrapping of the zeolite by the polymer. The water contact angle further increases with fiber alignment up to ~137º. Electrospun membranes are formed with ~80 % of the polymer crystalline phase in the electroactive  phase, independently on the electrospinning processing conditions or filler content. Viability of MC3T3-E1 cells on the composite membranes after 72 h of cell culture indicates the suitability of the membranes for tissue engineering applications.

“…4,7,8,11À14 The characteristic surface structures formed in this way can be used to tailor a great variety of surface properties, such as adhesion and friction, 14À16 induced cell alignment, 17 liquid crystal alignment, 18,19 and colored images generated by superficial gratings. 20 Typically, the more common way to investigate the morphology of LIPSSs is to carry out direct microscopic imaging of the surface by atomic force microscopy (AFM) 2,5À8, 13,16,17,19 or alternatively by scanning electron microscopy (SEM). 2À4,11,14,15,18 Quantitative information about the height and the period of the nanostructures is readily obtained by AFM over a range from several nanometers to several micrometers.…”

In this work we evaluate the potential of grazing incidence X-ray scattering techniques in the investigation of laserinduced periodic surface structures (LIPSSs) in a series of strongly absorbing model spin-coated polymer films which are amorphous, such as poly(ethylene terephthalate), poly(trimethylene terephthalate), and poly(carbonate bisphenol A), and in a weaker absorbing polymer, such as semicrystalline poly(vinylidene fluoride), over a narrow range of fluences. Irradiation was performed with pulses of 6 ns at 266 nm, and LIPSSs with period lengths similar to the laser wavelength and parallel to the laser polarization direction are formed by devitrification of the film surface at temperatures above the characteristic glass transition temperature of the polymers. No crystallization of the surface is induced by laser irradiation, and crystallinity of the material prevents LIPSS formation. The structural information obtained by both atomic force microscopy and grazing incidence small-angle X-ray scattering (GISAXS) correlates satisfactorily. Comparison of experimental and simulated GISAXS patterns suggests that LIPSSs can be well described considering a quasi-onedimensional paracrystalline lattice and that irradiation parameters have an influence on the order of such a lattice.
