Preparation and surface modification of electrospun aligned poly(butylene carbonate) nanofibers

Abstract

In this study, aligned poly(butylene carbonate) nanofibers were fabricated by electrospinning with a high‐speed transfer roller as the receiving device. Cold plasma treatment technology was applied to improve its hydrophilicity and activity to expand its application in biological materials. The morphology of the fibers was investigated with scanning electron microscopy. X‐ray diffraction was used to research the impact of the rotation speed on the crystallization and orientation degree of the crystals. The tensile properties of the materials were evaluated by a universal tester. The surface properties of the fibers pretreated by Helium (He) and those grafted with gelatin were evaluated with water contact angle measurement and X‐ray photoelectron spectroscopy. The experimental results indicate that the order degree of fibers, crystallinity, and orientation of the crystalline region, including the mechanical properties, all increased correspondingly with the rotation speed. After plasma pretreatment, the hydrophilicity was improved significantly, and the grafting reaction was realized successfully. © 2013 Wiley Periodicals, Inc. J. Appl. Polym. Sci., 2013

Improvement of thermal stability, crystallinity and degradation of poly(butylene carbonate) by incorporation of bio‐based poly(ethylene sebacate) segment

“…. The water contact angle of PBCU is about 104.9°, which shows that PBC is a typical hydrophobic material . Nevertheless, with the PESe segment content increasing, the water contact angle of PBC‐PESe1–4 decline from 89.2 to 80.5 o , which indicate that the hydrophilicity of PBC‐PESe improves along with the increasing content of incorporating PESe segment.…”

Electrospun anisotropic architectures and porous structures for tissue engineering

“…Furthermore, the surface modification of synthetic biomaterials with the intent to improve biocompatibility has been extensively studied. Many common techniques, such as plasma treatment [208][209][210] and gradients, 211 can be considered for the modification of aligned electrospun nanofibers. For instance, electrospun aligned poly(propylene carbonate) (PPC) microfibers were treated with oxygen plasma and chitosan nanofibers were introduced by freeze drying.…”

Effect of Cold Plasma Treatment on Electrospun Nanofibers Properties: A Review

“…136 Another pathway to graft peptides onto the surface of nanofibers by plasma is without the use of coupling agent according to a supposed mechanism detailed in Figure 13c. 138,144 It is important to note that the plasma gas used influences the procedure. Indeed, for direct coupling, O 2 and CO 2 are favored to create carboxylic acid functions.…”

“…Finally, Shao et al reported the low-pressure helium plasma treatment of poly(butylene carbonate) (PBC) nanofibers to graft gelatin, through polymer grafting without coupling, 144 and found that for a plasma power comprised between 20 and 80 W, the contact angle decreased rapidly and the absorption rate of the drop quickly increased. However, for a plasma power higher than 100 W, these characteristic rates started to decrease.…”
