Embodiment Construction

[0020] specific implementation plan

[0021] Further illustrate the present invention below in conjunction with accompanying drawing.

[0022] Such as figure 1 As shown, a droplet self-driven functional layer based on the surface energy gradient generated by the array gradient, the functional layer is divided into a plurality of continuous regions, each region has a plurality of hydrophilic patterns, and the other parts of the pattern Hydrophobic; the patterns are arranged in a matrix; the patterns are circular; from the matrix sampling end to the matrix detection end along the matrix axial direction, the area of ​​a single pattern in the area is the same, and the pattern spacing is gradually decreasing, correspondingly, the area The proportion of the hydrophilic region within the gradient increases.

[0023] It can be prepared by the following steps:

[0024] 1) Preparation of superhydrophobic titanium dioxide coating solution: mix 0.1g of titanium dioxide powder with a pa...

Abstract

The invention discloses a droplet self-driven functional layer based on a surface energy gradient generated by an array gradient; the functional layer can be used for detecting alcohol concentration;the functional layer is divided into a plurality of continuous areas, each area is provided with a plurality of hydrophilic patterns, and parts beyond the patterns are hydrophobic; the patterns are arranged in a matrix; the patterns are circular; the areas of the single patterns in each area are the same from a sampling end of a substrate to a detection end of the substrate along the axial direction of the substrate, and the distances between the patterns gradually decrease in a gradient; correspondingly, the proportion of the hydrophilic regions in the areas increases in a gradient. The functional layer has corresponding flow lengths for alcohol of different concentrations, so that the identification of the alcohol concentration is realized by spreading the length, and whether the concentration of medical alcohol is within an effective concentration range or not can be detected.

Description

technical field [0001] The invention relates to a droplet self-driven functional layer based on the surface energy gradient generated by the array gradient and its application in medical alcohol concentration detection. Background technique [0002] In daily life, it is common for some people to scrub wounds with medical alcohol to achieve the purpose of sterilization. But it is worth noting that different concentrations of alcohol have different uses, 40% to 50% alcohol can prevent bedsores, [0003] 25% to 50% alcohol can be used for physical fever reduction. Due to the volatility of alcohol, the concentration of alcohol will decrease with the passage of time, so the detection of the effectiveness of medical alcohol is very important. [0004] Alcohol concentration detection methods are generally divided into two categories, chemical methods and physical methods. Chemical methods are detection methods designed to take advantage of the chemical properties of alcohol. Th...
