“…However, a small new bond appeared around 1540 cm −1 , corresponding to carbonyl imide group beside the sharp carbonyl bond, which could confirm the chemical reaction conducted in Scheme 1 [27]. Further, the peak in 1093 cm −1 area confirmed COOH groups [16,28]. The broad peak formed in the area over 2500 cm −1 and a strong peak formed in the area 2921 cm −1 , which were not observed in the non-modified fiber spectrum, were likely related to the formation of the hydrogen bond between (NH 2 ) groups in the polymer latex with the (C = O) groups on the polyester fibers.…”

“…The nearly unchanged water retention was due to the strong water absorption, which was formed by the hydrogen bonding between carboxylate groups in PCA-PAEK polymer and water molecules. 32 At this stage, more than 72% water remained, demonstrating the polymer fibers had a good stability in water bonding. However, after 210 min, the water retention decreased dramatically.…”

As a high-performance polymer, carboxylic-functionalized poly(arylene ether ketone)s (PCA-PAEK) was electrospun into ultrafine fibers and characterized. To optimize the process, a set of experiments were designed. As a result, the optimum condition was obtained and the polymer concentration was determined as the most important factor. Incidentally, the PCA-PAEK fibers were found to exhibit superabsorbent behavior. In order to investigate processing characteristics, PCA-PAEK fibers fabricated from different solution concentrations were employed and characterized. The results showed that porosity and changes in water contact angle and water absorbency decreased with an increase in concentration. In addition to a high water absorption capacity, the fibers exhibited good water retention and repeated water absorbency as well. The study on kinetics of water absorption and swelling behavior showed that the mechanism was dependent on the polymer concentration from which the fibers were electrospun. Moreover, both dry and wet PCA-PAEK fibers showed high mechanical properties. Due to these properties, the PCA-PAEK ultrafine fibers are potentially useful as a water-absorbent material.

“…Absorption peaks of AMPS were observed at 1046 cm −1 , which demonstrated the SO group. The peaks at 1456 and 1406 cm −1 were related to the vibration of the bands H-C (CO) and CH 2 , respectively [23][24][25].…”
