Problems solved by technology

[0004] Currently, there is little literature on MXene-based superhydrophobic textiles
Moreover, most superhydrophobic textiles are directly soaked in low surface energy substances such as polydimethylsiloxane (PDMS), and there is a lack of firm bonding between low surface energy substances and textiles.

Abstract

The invention provides a durable super-hydrophobic cotton fabric and a preparation method thereof.The preparation method comprises the steps that cotton fabric oxidized through sodium periodate is placed in silver nitrate at the normal temperature for 30-60 min, then the cotton fabric is soaked in octadecylamine-KH560 modified Ti3C2Tx / TiO2 dispersion liquid for padding finishing, padding and rolling are conducted twice, the pick-up rate is controlled to be 100%, drying is conducted for 2 min at the temperature of 80 DEG C, shaping is conducted for 5 min at the temperature of 120 DEG C, and the durable super-hydrophobic cotton fabric is obtained. Finally, the durable super-hydrophobic cotton fabric with the characteristics of washing resistance, ultrasonic resistance, bending resistance, strong acid / alkali resistance and the like is prepared. The adhesive force between the octadecylamine-KH560 modified Ti3C2Tx / TiO2 and the cotton fabric is firm, and the octadecylamine-KH560 modified Ti3C2Tx / TiO2 is not easy to fall off from the surface of the cotton fabric, so that the super-hydrophobic property has long-term In addition, the durable super-hydrophobic cotton fabric also has the functions of antibiosis / antivirus, ultraviolet resistance, electromagnetic shielding, electric conduction and the like.

Description

technical field [0001] The invention relates to the fields of nanomaterials and textiles, in particular to a durable superhydrophobic cotton fabric and a preparation method thereof. Background technique [0002] Superhydrophobic surfaces are usually achieved through the modification of low surface energy substances and the construction of micro-nano rough structures. Due to its special surface wettability, it not only shows attractive prospects in the fields of self-cleaning, surface anticorrosion, oil-water separation, and anti-icing, but also has potential application value in daily life, biomedicine, and military fields. However, in the actual application process, low surface energy substances are easily decomposed by the stimulation of temperature, light, and strong oxidants, and the micro-nano rough structure is also easily damaged by physical effects such as mechanical friction or abrasion, thus affecting the adhesion of the coating. force and wettability, resulting i...
