Problems solved by technology

[0006] However, since surface hydrophobicity and transparency are two competing properties, the increase in hydrophobicity will decrease the transparency.
So far, there has been no report on the simultaneous acquisition of DLC films with wear resistance, hydrophobicity and light transmittance on the surface of polymer substrates.

Embodiment 1

[0034] In this embodiment, the transparent substrate is a PET substrate. Prepare diamond-like carbon film on this PET substrate surface by linear ion beam method, specifically as follows:

[0035] The surface morphology of the PET substrate before treatment is as follows: Figure 1A shown. First, the PET substrate was etched by Ar gas for 10 min, the linear ion beam current was 0.2A, and the Ar gas flow was 60 sccm; then, CH 4 and Ar gas, CH 4 The flow ratio with Ar gas is 15:30, CH 4 The flow rate is 15sccm, the linear ion beam current is 0.2A, and the deposition time is 20min, and a diamond-like carbon film is obtained, and its surface morphology is as follows: Figure 1B shown.

[0036] The naked eye transmittance of the PET substrate to visible light before and after coating is as follows: figure 2 As shown in , after testing, its light transmittance change curve for visible light is as follows image 3 shown. That is, compared with the PET substrate without deposi...

Embodiment 2

[0046] In the present embodiment, the transparent substrate is the same PET substrate as in Example 1, and a diamond-like carbon film is prepared on the surface of the PET substrate by a linear ion beam method, as follows:

[0047] First, the PET substrate was etched by Ar gas for 15 min, the linear ion beam current was 0.2A, and the Ar gas flow was 40 sccm; then, CH 4 and Ar gas, CH 4 The flow ratio with Ar gas is 15:45, CH 4 The flow rate is 15 sccm, the linear ion beam current is 0.1A, and the deposition time is 10 min to obtain a diamond-like carbon film.

[0048] After testing, the change curve of the light transmittance of the PET substrate to visible light before and after coating is as follows: image 3 shown. That is, compared with the PET substrate without depositing the diamond-like carbon film, after depositing the diamond-like carbon film on the surface of the PET substrate, it still maintains the high transmittance of the substrate itself for visible light; fo...

Embodiment 3

[0051] In the present embodiment, the transparent substrate is the same PET substrate as in Example 1, and a diamond-like carbon film is prepared on the surface of the PET substrate by a linear ion beam method, as follows:

[0052] First, pass O 2 Gas etched the PET substrate for 5min, the linear ion beam current was 0.15A, O 2 The air flow is 50sccm; then, pass into C 2 h 2 and Ar gas, C 2 h 2 The flow ratio with Ar gas is 6:60, C 2 h 2 The flow rate is 6 sccm, the linear ion beam current is 0.15A, and the deposition time is 30 min to obtain a diamond-like carbon film.

[0053] After testing, the change curve of the light transmittance of the PET substrate to visible light before and after coating is as follows: image 3 shown. That is to say, compared with the PET substrate without depositing the diamond-like carbon film, after depositing the diamond-like carbon film on the surface of the PET substrate, it maintains the high transmittance of the substrate itself for ...

Abstract

The invention provides a preparation method of a transparent hydrophobic abrasion-resistant diamond-like film on a transparent polymer surface. The method comprises the steps that firstly, the transparent polymer surface is subjected to plasma etching treatment; and secondly, the diamond-like film is deposited by introducing carbon source gas through a linear ion beam deposition method, and Ar gas is introduced during the deposition process of the diamond-like film, so that film deposition and gas etching are carried out simultaneously. The diamond-like film prepared through the method can maintain good abrasion resistance and transparency, has the hydrophobic characteristic, integrates the functions of abrasion resistance, transparency and hydrophobicity, and has good application prospects.

Description

technical field [0001] The invention relates to the technical field of transparent polymer surface treatment, and relates to a method for preparing a transparent, hydrophobic, wear-resistant, diamond-like film on the surface of a transparent polymer. Background technique [0002] In recent years, with the extensive use of polymer devices with good light transmission, the requirements for their transparency, hydrophobicity, wear resistance and other properties are getting higher and higher. Therefore, through surface modification technology, screen suitable surface coating materials to obtain protective coatings with high wear resistance, high transparency and hydrophobicity on the surface of transparent polymers. , self-cleaning and other fields have very important development value. [0003] There are not many studies on transparent hydrophobic coatings at home and abroad. Through literature research, some reported preparation methods have been found, such as plasma-enhanc...
