“…Upon longer acetylation (2 h and 3 h; Figure 2d,e, respectively), the fibers appeared rougher, possibly as a result of swelling that was caused by the pyridine catalysis used for the acetylation reaction. Indeed, pyridine is known to swell and open cell walls in fibers to ease penetration of acetic anhydride [19,25]. In summary, fiber surface morphology was altered depending on the extent of acetylation; the morphology changes could be related to the chemistry occurring on and in the fibers.…”

As a result of industrialization and environmental pollution, increasing importance is being given to eco-friendly materials and technology. In particular, eco-friendly biocomposites using polylactic acid (PLA) have attracted great interest. In this work, fiber-reinforced composites were investigated in order to enhance the mechanical properties and improve the economic efficiency of PLA. Specifically, composite materials using natural fibers, such as kenaf were actively studied. In the utilization of natural fibers, such as kenaf, the treatment method for increasing the bonding force between the fiber and the matrix is very important. In this study, the surface of kenaf was treated using an acetylation technique, and the PLA composite material was prepared using surface-treated kenaf. Changes in fiber properties were observed with acetylation treatment time. The mechanical properties, thermal stability, and water absorption resistance of the acetylated kenaf and PLA composites prepared for each condition were evaluated. Finally, was concluded that acetylation treatment is effective for improving the performance of PLA/kenaf composites. This behavior was found to relate to the surface cleaning of acetylated kanaf, in addition to the efficient modification of the hydrophilic characteristics of kenaf.

“…BC has been used as reinforcement in different polymeric matrices such as cellulose acetate butyrate, polylactic acid, polyhydroxy butyrate, starch, hydroxyl ethyl cellulose, polyvinyl alcohol, acrylic resin, epoxidised soyabean oil etc [17,[19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35]. In the ex situ synthesis of BC nanocomposites the penetration of the second component through the BC network may not be uniform which results into a non-homogeneous structure.…”

In the present study nanocomposite fibers and film scaffolds based on poly (2-hydroxy ethyl methacrylate) and microcrystalline cellulose were prepared by electrospinning method and solvent casting method, respectively. Paclitaxel (20 ppm) was incorporated during the preparation of fibers and film to result in paclitaxelincorporated nanocomposite film and fibers with an encapsulation efficiency of 63% and 72%, respectively. These prepared nanocomposite films and fibers were characterized and confirmed by FTIR, XRD and SEM analysis. The biocompatibility of the nanocomposite scaffolds were assessed using VERO cell lines. The in vitro release of paclitaxel from the nanocomposite fibers, and film was found to be 74 AE 1.2% and 64 AE 1.2%, respectively.
