“…However, the authors did not examine the effect of these plasma‐polymerized heptylamine coatings on cell adhesion and proliferation. Besides allylamine and heptylamine, also acrylic acid has been plasma‐polymerized on the surface of biodegradable polyesters 154–156. This plasma polymerization method creates hydrophilic surfaces containing a high amount of COOH groups, which can significantly enhance cell attachment and proliferation 154, 155…”

Besides their use as packaging materials, biodegradable polymers can play a major role in tissue engineering as three‐dimensional porous structures (scaffolds). The success of these biodegradable scaffolds is, however, determined by the response it elicits from the surrounding biological environment and this response is governed, to a large extent, by the surface characteristics of the scaffold. Multiple approaches have been developed to obtain the desired surface properties, however, in the past decade, the use of non‐thermal plasmas for selective surface modification has been a rapidly growing research field. This paper therefore presents a critical overview on recent advances in plasma‐assisted surface modification of biodegradable polymers.

“…Zhao et al . () reported that PBS films functionalized by AAc plasma grafting presented a typical biodegradation pattern with micro‐cracked and fragmented surfaces. The surface modification by NaOH has also been reported to induce significant changes in the surface properties of jute fibres in PBS–jute fibre biocomposites (Liu et al ., ).…”

“…There are a number of approaches that can tailor the surface characteristics of complex shaped 3D structures for TE applications (Pashkuleva and Reis, ; Yoo et al ., ). As a biodegradable aliphatic polyester, PBS is particularly susceptible to surface modification (Zhao et al ., ; Liu et al ., ; Martins et al ., ). Plasma and ultraviolet (UV) irradiation are among the techniques used either for surface modification of biomaterials or for activation of the surfaces before grafting with different functional molecules (Liu et al ., ; Li et al ., ).…”

Textile-based technologies are powerful routes for the production of three-dimensional porous architectures for tissue engineering applications because of their feasibility and possibility for scaling-up. Herein, the use of knitting technology to produce polybutylene succinate fibre-based porous architectures is described. Furthermore, different treatments have been applied to functionalize the surface of the scaffolds developed: sodium hydroxide etching, ultraviolet radiation exposure in an ozone atmosphere and grafting (acrylic acid, vinyl phosphonic acid and vinyl sulphonic acid) after oxygen plasma activation as a way to tailor cell adhesion. A possible effect of the applied treatments on the bulk properties of the textile scaffolds has been considered and thus tensile tests in dry and hydrated states were also carried out. The microscopy results indicated that the surface morphology and roughness were affected by the applied treatments. The X-ray photoelectron spectroscopy and contact angle measurements showed the incorporation of oxygen-containing groups and higher surface free energy as result of the surface treatments applied. The DNA quantification and scanning electron microscopy analysis revealed that these modifications enhanced cell adhesion and altered cell morphology. Generally, sodium hydroxide treatment altered most significantly the surface properties, which in turn resulted in a high number of cells adherent to these surfaces. Based on the results obtained, the proposed surface treatments are appropriate to modify polybutylene succinate knitting scaffolds, influencing cell adhesion and its potential for use in tissue engineering applications.

“…Plasma-induced graft polymerization has been widely applied as a simple, useful and versatile approach in surface functionalization of polymeric materials [1][2][3][4]. When polymers are exposed to plasmas, the irradiation transfers its energy to the polymers through inelastic collisions between the fast moving active species and the substrate surface molecules, leading to free radical formation by chain scission and abstraction (taking-off of atoms on molecular chain) reactions [5].…”
