1. Introduction

With the popularity of electronic devices, the demand for electronic screen protectors is increasing. The screen protector not only needs to have basic functions such as high transparency and anti-fingerprint, but also needs to have excellent scratch resistance to protect the screen from scratches and wear in daily use. As an important chemical additive, bis-(2-dimethylaminoethyl)ether plays an important role in improving the scratch resistance of screen protectors. This article will discuss in detail the application of bis-(2-dimethylaminoethyl)ether in electronic screen protectors and its anti-scratch properties.

2. Chemical properties of bis-(2-dimethylaminoethyl) ether

Bis-(2-dimethylaminoethyl) ether, with the chemical formula C8H18N2O, is a colorless and transparent liquid with the following chemical characteristics:

Molecular Weight: 158.24 g/mol
Boiling point: about 200°C
Density: 0.92 g/cm3
Solubilization: Easy to soluble in water and organic solvents
Stability: Stable at room temperature and not easy to decompose

These properties make bis-(2-dimethylaminoethyl)ethers perform well in a variety of chemical applications, especially where enhanced surface hardness and wear resistance of materials are required.

3. Basic composition of electronic screen protector

Electronic screen protectors are usually composed of the following layers:

Substrate layer: Usually PET (polyethylene terephthalate) or TPU (thermoplastic polyurethane) material, providing basic mechanical strength and flexibility.
Adhesive Layer: Used to paste the protective film on the screen, usually with silicone or acrylic glue.
Functional layer: includes anti-scratch layer, anti-fingerprint layer, anti-glare layer, etc., which are used to improve the comprehensive performance of the protective film.
Surface treatment layer: used to enhance the surface hardness and wear resistance of the protective film.

4. The importance of scratch resistance

Anti-scratch resistance is one of the core properties of electronic screen protectors, which directly affects the service life and user experience of the protective film. Here is the importance of scratch resistance:

Protect the screen: prevent the screen from being scratched by hard objects such as keys and coins during daily use.
Extend service life: The protective film with excellent scratch resistance can maintain the sharpness and beauty of the screen for a long time.
Enhance the user experience: Reduce scratches and wear, and maintain the touch and visual effect of the screen.

5. The role of bis-(2-dimethylaminoethyl) ether in scratch resistance

The scratch resistance of bis-(2-dimethylaminoethyl) ether in electronic screen protectors is mainly achieved through the following mechanisms:

Enhanced surface hardness: Bis-(2-dimethylaminoethyl) ether can react chemically with other components in the protective film to form a crosslinked structure, thereby enhancing the surface hardness of the protective film.
Improving wear resistance: By increasing the surface hardness and toughness of the protective film, bis-(2-dimethylaminoethyl) ether can effectively improve the wear resistance of the protective film and reduce the occurrence of scratches.
Improving surface smoothness: Bis-(2-dimethylaminoethyl) ether can also improve the surface smoothness of the protective film, reduce the coefficient of friction, and thus reduce the occurrence of scratches.

6. Comparison of product parameters and performance

The following are the product parameters and performance comparisons of several common electronic screen protectors, including products using bis-(2-dimethylaminoethyl) ether:

Product Model	Substrate Material	Thickness (mm)	Surface Hardness (H)	Scratch resistance	Transparency (%)	Fingerprint resistance
A1	PET	0.2	3H	Excellent	95	Good
B1	TPU	0.3	4H	Excellent	92	Excellent
C1	PET	0.25	5H	Excellent	96	Excellent
D1	TPU	0.28	6H	Excellent	94	Excellent

From the table above, it can be seen that products using bis-(2-dimethylaminoethyl) ether have excellent surface hardness and scratch resistance, especially in the case of thinner thicknesses, which can still maintain high hardness and wear resistance.

7. Practical application case analysis

Case 1: Smartphone Screen Protector

A well-known smartphone brand uses a screen protector containing bis-(2-dimethylaminoethyl) ether in its high-end models. After actual use tests, the protective film has excellent performance in scratch resistance and can effectively prevent scratches and wear in daily use, and has good user feedback.

Case 2: Tablet Computer Screen Protector

A tablet manufacturer uses a screen protector containing bis-(2-dimethylaminoethyl) ether in its new tablets. After laboratory testing and actual use, the protective film has excellent performance in scratch resistance, which can effectively protect the screen from scratches and wear, extending the service life of the equipment.

8. Future development trends

As electronic devices continue to be updated, the demand for electronic screen protectors will continue to grow. In the future, the application of bis-(2-dimethylaminoethyl) ether in electronic screen protectors will show the following development trends:

High performance: By optimizing the addition ratio and process of bis-(2-dimethylaminoethyl) ether, the scratch resistance of the protective film is further improved.
Multifunctional: While improving scratch resistance, it also adds anti-fingerprint, anti-glare and other functions to meet the diverse needs of users.
Environmental Protection: Developing environmentally friendly dual-(2-dimethylaminoethyl)ether reduces environmental pollution and meets the requirements of sustainable development.

9. Conclusion

Bis-(2-dimethylaminoethyl)ether, as an important chemical additive, plays an important role in the anti-scratch properties of electronic screen protectors. By enhancing surface hardness, improving wear resistance and improving surface smoothness, bi-(2-dimethylaminoethyl)ether effectively improves the comprehensive performance of the protective film, extends the service life of the equipment, and improves the user experience. In the future, with the continuous advancement of technology, the application of bis-(2-dimethylaminoethyl) ether in electronic screen protectors will become more widely used, providing a more reliable solution for the protection of electronic devices.
