“…We were unable to perform the electrospinning procedure with solutions with a concentration of greater than 40% copolymer. Other studies dispersing conductive elements in solution have also found difficulty with electrospinning at higher concentrations . Part of this difficulty may be a result of partially charged areas on the PPy–PCL molecules (or conductive particles in general) interacting strongly with the applied voltage and disrupting the electrospinning process.…”

Advancements in tissue engineering and biomaterial development have the potential to provide a scalable solution to the problem of large-volume skeletal muscle defects. Previous research on the development of scaffolds for skeletal muscle regeneration has focused on strategies for increasing conductivity, which has improved satellite cell attachment and differentiation. However, these strategies usually increase scaffold stiffness, which some studies suggest may be detrimental to myoblast development. In this study, the polymers polypyrrole (PPy) and polycaprolactone (PCL) were synthesized together into a copolymer (PPy-PCL) designed to increase scaffold conductivity without significantly influencing stiffness. Different scaffold groups were fabricated via electrospinning, characterized, and assessed for their suitability for myoblast proliferation and differentiation. The groups included an aligned and random iteration of pure PCL, 10% PPy-PCL, 20% PPy-PCL, and 40% PPy-PCL. Only the 40% PPy-PCL group had a measureable conductivity, and the addition of PPy-PCL had no significant effect on the stiffness of the scaffolds. The PPy-PCL copolymer significantly increased the attachment of C2C12 myoblasts as compared to pure PCL scaffolds, but the concentration of PPy-PCL did not significantly alter cell attachment. In addition, scaffolds with PPy-PCL promoted myoblast differentiation to a greater extent than scaffolds made of PCL as measured by fusion index and number of nuclei per myotube. Aligned scaffolds were superior to random scaffolds in almost all measures. These results suggest that conductivity may not be the key factor in improving skeletal muscle scaffolds. Instead, cell attachment and aligned guidance cues may have a greater impact on myoblast differentiation.

There has been a steady progress in developing synthetic fibers in the past few years. Bicomponent fibers and nanofibers in a core/shell (C/S) configuration, including two dissimilar materials have presented unusual potential for use in many novel applications. These fibers can be produced using a variety of materials via different techniques i.e., coaxial melt spinning and electrospinning. In this review, we discuss the recent advances in C/S fibers and nanofibers' production. The first part has been assigned to the bicomponent fibers manufacturing technology, while production and applications of C/S nanofibers have been described in the second part.

Günümüzde, sentetik lifler insanların yaşamında önemli rol oynamaktadır. Sentetik lifler ve bu liflerden oluşturulan tekstil yüzeyleri, geleneksel tekstil ürünlerinin yanı sıra, hava yastığı, kord bezi, filtreler, kompozit malzemeler, konveyör bantlar, optik malzemeler, ısı ve ses yalıtım malzemeleri gibi teknik tekstil endüstrisinde pek çok uygulamada kullanılmaktadır. Bikomponent lif üretimi farklı iki polimerin birlikte çekilmesi esasına dayanan sentetik lif üretim yöntemlerinden birisidir. Bu yöntemle liflere farklı özellikler kazandırılabilmektedir. Son kullanım yerine bağlı olarak, lif kesiti seçilerek, özel lifler üretmek mümkündür. Bikomponent lifler, ticari olarak da ilgi görmektedir. Bu makalede; bikomponent liflerin tarihçesi, bikomponent lif tanımı, üretim yöntemleri ve bikomponent lif pazarının durumu özetlenerek, ticari bikomponent liflere ve özellikle son yıllardaki literatür çalışmalarına yer verilmiştir.
