摘要
单向导水织物在吸湿排汗服饰、土壤稳定、水资源管理、农业、环境保护等领域中广泛应用,但是目前制备单向导水织物往往使用有机溶剂和含氟化学品,对环境、人体健康等造成危害.本文基于水基无氟方法制备单向导水织物,先对织物进行聚多巴胺涂层处理,然后将十六烷基三甲氧基硅烷水解产物通过静电纺丝的方法喷涂在聚多巴胺修饰的织物单面,形成防水的单面.由于没有喷涂的一面保持超亲水的特性,织物就形成了从超亲水到超疏水的梯度结构,从而具有单向导水的性质.此制备方法安全环保,具有广泛的应用前景.
Abstract
Directional water transport fabrics have found extensive applications in various fields such as moisture-wicking clothing,soil stabilization,water resource management,agriculture,environmental protection,etc.However,the current manufacturing process of directional water transport fabrics often involves the use of organic solvents and fluorinated chemicals,posing hazards to the environment and human health.This paper introduces a waterborne,fluorine-free approach for producing directional water transport fabrics.The fabric is initially treated with a polydopamine coating,followed by the application of hexadecyltrimethoxysil-ane hydrolysis products using electrospinning on one side of the polydopamine-modified fabric,creating a water-resistant surface.Since the untreated side retains its superhydrophilic properties,the fabric forms a gradient structure ranging from superhydrophilic to superhydrophobic,thereby exhibiting directional water transport property.The preparation method is safe and environmentally friendly,and has wide application prospects.
