“…In general, under inert atmosphere, both polymers showed a single‐stage thermal degradation. The PCL nanofiber membrane was completely degraded from 345 to 470 °C with total weight loss (100%) by 430 °C, as reported in the literature . The PA‐6 nanofiber was almost completely degraded from 355 to 503 °C with weight loss of 95.78% at 456.4 °C, similar to the results found by Komalan et al .…”

Nowadays, efficient, economical, and environmentally friendly materials for the removal of emerging contaminants from the aquatic environment have been sought. Electrospun nanofibrous membranes contain fibers with diameters of submicron or nanometer scale, making them very promising adsorbent materials for use in several areas. In this context, the present study aims to synthesize and apply polymeric nanofiber membranes for solid‐phase extraction of estriol from aqueous solution. Nanofiber membranes of poly(ε‐caprolactone) (PCL) and polyamide‐6 (PA‐6) were tested as adsorbent materials and characterized by different techniques. The electrospinning time was evaluated, and the highest removal obtained for the PA‐6 nanofiber was 76.5%, spun for 100 min, whereas for the PCL nanofiber, 80% time‐independent removal was obtained. The thinner nanofibers had a larger contact area, therefore higher removals, except for the PCL nanofiber, which presented exposed beads on smaller thicknesses that impaired their efficiency. Furthermore, the nanofiber membranes have been applied for the determination of 1.0 mg L−1 of E3 in superficial water sample with satisfactory results. These aspects demonstrate that the synthesized nanofibers present an efficient material for the extraction of estriol: of high simplicity, low cost, and using green chemistry. © 2018 Wiley Periodicals, Inc.

“…The associated use of keratin and PCL was mainly explored for fibre casting via the electrospinning technique, especially for cell proliferation scaffolds and supports with controlled mechanical properties, where the α-keratin sources were wool and hair, such as the case of Li et al, [177] that prepared nanonets of wool keratin and poly(ε-caprolactone) (PCL) via one-step electrospinning with formic acid. A dual structure was formed consisting of randomly oriented D = 299-624 nm nanofibers and dense spider-web-like D = 25 ± 5 nm nanonets, with nanonet formation only at large keratin amounts (≥25 wt.…”

“…%). The keratin addition to the structure formed hydrophilic nanonets decreasing the water contact angles 20-50 degrees; however, the mechanical properties also suffered a sharp decline in comparison to the neat PCL nanofibers [177]. Later on, the same group prepared similar electrospun blends with different ratios of wool keratin and PCL for accessing their morphology, biodegradation degree (in phosphate buffer saline, PBS) and cell proliferation.…”

Among the biopolymers from animal sources, keratin is one the most abundant, with a major contribution from side stream products from cattle, ovine and poultry industry, offering many opportunities to produce cost-effective and sustainable advanced materials. Although many reviews have discussed the application of keratin in polymer-based biomaterials, little attention has been paid to its potential in association with other polymer matrices. Thus, herein, we present an extensive literature review summarizing keratin’s compatibility with other synthetic, biosynthetic and natural polymers, and its effect on the materials’ final properties in a myriad of applications. First, we revise the historical context of keratin use, describe its structure, chemical toolset and methods of extraction, overview and differentiate keratins obtained from different sources, highlight the main areas where keratin associations have been applied, and describe the possibilities offered by its chemical toolset. Finally, we contextualize keratin’s potential for addressing current issues in materials sciences, focusing on the effect of keratin when associated to other polymers’ matrices from biomedical to engineering applications, and beyond.

“…The presence of keratin containing rich amino and carboxylic groups led to an improvement of the hydrophilicity and wettability of the CHT membrane, which has been reported before. 61 This is linked to the fact that keratin is a naturally hydrophilic protein. 56 The capacity to react with water is also visible in the weight loss and water uptake properties of the CHT/keratin membranes.…”
