The development of multifunctional textiles can be achieved through coating techniques. Natural rubber latex (NRL) presents a promising bio-based coating material. Although, NRL can improve the mechanical properties, NRL alone does not provide multifunctionality. Therefore, incorporating filler into NRL is essential to impart additional functionalities to textiles. This study presents a facile method for fabricating multifunctional textiles by combining NRL with tannic acid (TA)-exfoliated molybdenum disulfide (MoS) nanosheets (MT). MoS was exfoliated using TA via sand grinding, and the resulting nanosheets dispersion was incorporated into NRL, which was then applied to polycotton fabric via a single dipping method. Coating with NRL alone lacked functional properties and MoS without TA led to aggregation. TA alone also failed to improve certain properties. However, the synergy among NRL, MoS and TA significantly improved the mechanical strength, antibacterial properties, hydrophilicity, self-cleaning ability, stain removal efficiency, acid resistance, ultraviolet blocking, and washing durability. These multifunctional coated fabrics hold great potential for application in medical and protective clothing.
多功能纺织品的开发可通过涂层技术来实现。天然橡胶乳胶（NRL）是一种很有前景的生物基涂层材料。尽管NRL能改善机械性能，但仅NRL本身并不能提供多功能性。因此，在NRL中加入填料对于赋予纺织品额外的功能至关重要。本研究提出了一种通过将NRL与单宁酸（TA）剥离的二硫化钼（MoS）纳米片（MT）相结合来制备多功能纺织品的简便方法。通过砂磨用TA对MoS进行剥离，然后将所得的纳米片分散体加入到NRL中，接着通过单次浸渍法将其应用于涤棉织物。单独用NRL涂层缺乏功能特性，而没有TA的MoS会导致聚集。单独的TA也无法改善某些性能。然而，NRL、MoS和TA之间的协同作用显著提高了机械强度、抗菌性能、亲水性、自清洁能力、去污效率、耐酸性、紫外线阻隔性能和洗涤耐久性。这些多功能涂层织物在医疗和防护服领域具有巨大的应用潜力。
