A Study on Extraction and Characterization of Keratin Films and Nanofibers from Waste Wool Fiber

ABSTRACT

Fabrication and characterization of keratin films extracted from waste Merino wool fiber using two different methods and three different pH concentrations is the main focus of this study. Also, wool keratin (WK) loaded polymer surfaces were fabricated. The chemical, structural and morphological characteristics of keratin extracted from aqueous solutions were analyzed and compared for both methods. It is concluded that optimized results in this study could contribute in future research studies to select the parameters and methods to extract keratin films from recyclable wool fibers. Also, WK loaded nanofibrous films could be potential in filtration, air purification and tissue engineering.

摘要

用两种不同的方法和三种不同的pH浓度从废美利奴羊毛纤维中提取角蛋白膜的制备和表征是本研究的主要焦点。同时，制备了羊毛角蛋白负载聚合物表面。从两种方法中分析和比较了从水溶液中提取的角蛋白的化学、结构和形态特征。结果表明，本研究的优化结果有助于今后研究从可回收羊毛纤维中提取角蛋白膜的参数和方法。此外，羊毛角蛋白负载纳米纤维膜在过滤、空气净化和组织工程方面具有潜在的应用前景。
