摘要

纺织业正在迅速发展,以满足消费者对先进、功能性产品日益增长的需求。虽然传统纺织品在机械强度、耐用性和阻燃性等方面有所改善,但由于保持水分,棉织物仍然容易受到微生物降解的影响。本研究提出了一种利用氮化硼(BN)和纳米银(Ag NPs)赋予棉织物抗菌性能的新方法。合成了银饰BN (BN- ag),并将其羧基官能团化,与棉纤维素形成强酯键,显著提高了对革兰氏阳性金黄色葡萄球菌(S. aureus, 99.57%)和革兰氏阴性大肠杆菌(E. coli, 99.64%)的抑菌效果。BN-Ag处理后织物的抗氧化活性(51.78%)和紫外线(UV)防护能力(UVA防护能力为98.39%,UVB防护能力为98.4%)均优于未处理棉。此外,热阻降低了21.23%,表明智能纺织品应用的散热得到了改善。紫外线防护系数(UPF)分析将BN-Ag织物列为优秀的紫外线防护剂(UPF为62.56)。长期稳定性评估表明,经20次家庭洗涤6个月后,织物的抗菌效果(对金黄色葡萄球菌的抗菌效果为97.61%,对大肠杆菌的抗菌效果为97.11%)和抗氧化活性(抗氧化活性为43.73%)保持不变,显示出功能性能的耐久性。这种创新的方法有望彻底改变纺织材料,提高各种应用的性能和性能。

Silver-decorated boron nitride nanocomposite-infused cotton fabric with durable antimicrobial and multifunctional properties

Silver-decorated boron nitride nanocomposite-infused cotton fabric with durable antimicrobial and multifunctional properties
The textile industry is rapidly evolving to meet growing consumer demands for advanced, functional products. While traditional textiles have improved in mechanical strength, durability, and attributes like flame retardancy, cotton fabrics remain vulnerable to microbial degradation due to moisture retention. This study presents a novel approach that utilizes boron nitride (BN) and silver nanoparticles (Ag NPs) to impart antimicrobial properties to cotton fabrics. Silver-decorated BN (BN-Ag) was synthesized and functionalized with carboxyl groups, enabling strong ester bond formation with cotton cellulose, significantly enhancing antimicrobial efficacy against Gram-positive Staphylococcus aureus (S. aureus, 99.57%) and Gram-negative Escherichia coli (E. coli, 99.64%). The BN-Ag treated fabric exhibited impressive antioxidant activity (51.78%) and ultraviolet (UV) protection (98.39% for UVA and 98.4% for UVB), surpassing untreated cotton. Furthermore, thermal resistance was reduced by 21.23%, indicating improved heat dissipation for smart textile applications. UV protection factor (UPF) analysis classified BN-Ag fabrics as excellent UV protectors (UPF 62.56). Long-term stability assessments revealed that the fabrics maintained antimicrobial efficacy (97.61% against S. aureus and 97.11% against E. coli) and antioxidant activity (43.73%) after six months with 20 home washes, demonstrating the durability of functional properties. This innovative approach promises to revolutionize textile materials, enhancing properties and performance for diverse applications.
