基于肽增强的纳米纤维素高性能材料Peptide-Enhanced Nanocellulose for High-Performance Materials
➀ 米兰理工大学的研究人员及其合作机构利用纤维素纳米纤维的机械特性和防水性开发了疏水性纸张，旨在为包装和生物医学应用创造可持续、高性能的材料。➁ 通过不进行化学改性的方法，将短蛋白链（肽）与纤维素纳米纤维结合，显著提高了其机械性能和防水性。➂ 在肽中引入氟原子，形成结构化的疏水薄膜，提高了防水性，同时保持了生物相容性和可持续性。➀ Researchers from Politecnico di Milano and collaborating institutions developed hydrophobic paper using the mechanical properties and water resistance of cellulose nanofibers. The study aims to create a sustainable, high-performance material for packaging and biomedical applications. ➁ The approach combines short protein chains (peptides) with cellulose nanofibers without chemical modification, enhancing their mechanical performance and water resistance. ➂ Incorporating fluorine atoms into the peptides creates a structured hydrophobic film, improving water resistance while maintaining biocompatibility and sustainability.
