specific Embodiment approach 1

[0021] Specific implementation mode one: the method for biomimetic preparation of high-adhesion superhydrophobic on the surface of bamboo in this embodiment is implemented according to the following steps:

[0022] 1. The bamboo is cleaned and air-dried to obtain the cleaned bamboo;

[0023] 2. Place the cleaned bamboo into the cavity of the magnetron sputtering device, use the copper target as the target, and control the vacuum in the cavity to 5×10 -3 ~1×10 -2 Pa, the argon gas flow rate is 20-60sccm, the RF power is 40-400W for pre-sputtering for 10-20 minutes, then adjust the RF power to 300-400W, the reverse sputtering power is 5-10W, and the sputtering pressure is 1.0-1.5 Pa carries out sputter coating, obtains the bamboo of surface coating;

[0024] 3. Soak the coated bamboo in a stearic acid solution, take it out, ultrasonically clean it, and dry it to complete the bionic preparation of high-adhesion superhydrophobic on the surface of the bamboo.

[0025] In this em...

specific Embodiment approach 2

[0026] Embodiment 2: The difference between this embodiment and Embodiment 1 is that in step 1, the bamboo is placed in deionized water for ultrasonic cleaning. Other steps and parameters are the same as those in Embodiment 1.

specific Embodiment approach 3

[0027] Embodiment 3: This embodiment differs from Embodiment 1 or Embodiment 2 in that the temperature inside the cavity of the magnetron sputtering device in Step 2 is 25-35°C. Other steps and parameters are the same as those in Embodiment 1 or Embodiment 2.

Abstract

The invention discloses a bionic preparation method for a high-adhesion super-hydrophobic surface on a bamboo surface, and relates to a bionic preparation method for a high-adhesion super-hydrophobic surface on a bamboo surface, and the bionic preparation method aims to solve the problems that a method of constructing a super-hydrophobic surface on a bamboo surface at present is complex in process, and the super-hydrophobic surface is relatively low in hydrophobic and adhesive property. The method for preparing the high-adhesion super-hydrophobic surface comprises the following steps of: I, cleaning the bamboo; II, putting the bamboo into a cavity of a magnetron sputtering device, taking a copper target as a target material to carry out pre-sputtering for 10-20 minutes, and carrying out sputtering coating by regulating radio frequency power to be 300-400 W, re-sputtering power to be 5-10W and sputtering pressure intensity to be 1.0-1.5 Pa; and III, putting the surface-coated bamboo into a stearic acid solution to soak, and finally drying. The high-adhesion super-hydrophobic surface constructed on the bamboo surface has good high-adhesion super-hydrophobic property, so that contact angles, on the high-adhesion super-hydrophobic surface, of water drops are 153 degrees.

Description

technical field [0001] The invention relates to a method for preparing a high-adhesion super-hydrophobic surface on bamboo. Background technique [0002] my country's bamboo resources are very rich, but wood resources are relatively scarce. With the adjustment of my country's forestry policy, more emphasis on environmental protection, and the improvement of resource crisis awareness, the development space for wood as a building material has been greatly reduced. Bamboo, as a green material, is bound to enter the public eye. Bamboo itself has the characteristics of good earthquake resistance, eco-environmental protection, sufficient raw materials, heat preservation, and sound insulation. [0003] However, in practical application, the disadvantages of bamboo are more obvious. Once it is exposed to the sun and moisture, it is prone to delamination. In humid areas, it is more prone to mold and insects, which seriously affects the service life of bamboo. [0004] The Chinese p...
