Description
Technical Field
The invention relates to the technical field of nano materials, in particular to Ag @ Zn (OH)2A preparation process of nano-sheet conductive cotton cloth.
Background
The extremely wet super-hydrophobic solid surface with the contact angle larger than 150 degrees has great potential application value in high-tech fields such as corrosion resistance, antifogging, antibiosis, antifreezing, self-cleaning, oil-water separation, liquid lens, micro-fluidic control and the like and daily life. The conductivity is also a key technical requirement for the application of the super-hydrophobic material in the field of flexible electronic equipment. The combination of electrical conductivity and superhydrophobicity not only imparts versatility to flexible materials (e.g., electronic skin, electromagnetic interference (EMI) shielding, electric heaters, and wearable devices), but also ensures their long-term use in wet or corrosive environments. However, flexible electronics still have some drawbacks, and the complexity and time consuming manufacturing process and the sensitivity to the environment are one of the main drawbacks, so that achieving integration of electrical conductivity with superhydrophobicity in textiles is a huge challenge. Although the current development of Superhydrophobic Conductive Textiles (SCT) has achieved a range of results, there are significant distances from practical use in terms of conductivity, cost accounting, and mechanical stability. It is undoubtedly the most straightforward and simple method to modify the surface of flexible cotton cloth with conductive superhydrophobic coatings due to the renewable nature and low cost of cotton cloth. At present, only a few conductive super-hydrophobic coatings are reported, the preparation process of the coatings is complex and expensive, even a plurality of coatings contain toxic substances, the environment is polluted, the adhesion force of the coatings and flexible textiles is weak, the coatings are easy to fall off, and the problems prevent the large-scale application of the super-hydrophobic conductive coatings in the actual life production. Therefore, the synthesis process of the super-hydrophobic conductive cloth which is environment-friendly, low in cost, high in mechanical stability and capable of being prepared on a large scale is still very necessary.
The metal silver (Ag) has high conductivity and is environment-friendly. Zinc hydroxide (Zn (OH)2) Is an inorganic compound with simple preparation method and lower cost, has no toxicity, and is obviously an ideal base material for preparing the super-hydrophobic coating. But the surface energy is higher, the super-hydrophobic property is not possessed, and the electric conduction is realized.
