This work analyses the properties of calcium phosphate coatings obtained by pulsed laser deposition on the surface of the ferroelectric polymer material. Atomic force and scanning electron microscopy studies demonstrate that, regardless of the type of sputtering target, the calcium phosphate coatings have a multiscale rough surface that is potentially capable of promoting the attachment and proliferation of osteoblasts. This developed surface of the coatings is due to its formation mainly from a liquid phase. The chemical and crystalline 2 composition of the coatings depends on the type of sputtering target used. It was shown that, regardless of the type of sputtering target, the crystalline structure of the ferroelectric polymer material does not change. Cell viability and adhesion studies of mesenchymal stromal cells on the coatings were conducted using flow cytometry and fluorescent microscopy. These studies indicated that the produced coatings are non-toxic.

“…However, the hydrophobic property of PVDF causes fouling and decreases the life of the membrane. Various methods for modification of PVDF have been reported [2][3][4][5]. In one of these methods, the PVDF membrane surface was modified by grafting with active compounds using high-energy radiation [2].…”

“…Another method highlighted PVDF modification using a surface impregnation coating with active compounds such as hydroxypropyl cellulose (HPC) [3]. Radiation treatment was also suggested to create surface defects, which may act as active sites for the attachment of suitable compounds to the surface [4]. It has been well established that the mixing or blending of hydrophobic commercial polymers with active monomers such as acrylic acid increased hydrophilicity and enhanced their properties [5].…”

Poly(vinylidene fluoride) (PVDF) was modified with a styrene-based copolymer. The crystalline behavior, phase, thermal stability, and surface morphology of the modified membranes were analyzed. The membrane surface roughness showed a strong dependence on the styrene-acrylonitrile content and was reduced to 34% for a PVDF/styrene-acrylonitrile blend membrane with a 40/60 ratio. The thermal and crystalline behavior confirmed the blend miscibility of both polymers. It was observed in X-ray diffraction (XRD) experiments that the modified PVDF membranes show a drastic reduction in their crystallinity. The neat PVDF membrane has the highest degradation rate, which decreased with the addition of the styrene-based copolymer.

“…In addition to its use for biocompatibility applications, PTFE has also been employed as self-cleaning coating [8][9][10]. Other widely used fluoropolymers such as PVDF and PFA have been plasma-treated to improve their chemical and mechanical properties [11][12][13][14].…”

Among various surface modification techniques, plasma can be used as a source for tailoring the surface properties of diverse materials. HDPE and fluoropolymer surfaces have been treated by the post-discharge of an atmospheric RF-plasma torch supplied with helium and oxygen gases. The plasma-treated surfaces were characterized by measurements of mass losses, water contact angles, x-ray photoelectron spectroscopy and atomic force microscopy. This experimental approach correlated with an optical characterization of the plasma phase allowed us to propose etching mechanisms occurring at the post-discharge/polymer interface. We discuss how competitive and synergistic effects can result from the oxidation and/or the roughening of the surface but also from the excimer VUV radiation, the He metastable species and the O radicals reaching the plasma-polymer interface.
