1. Introduction

Smart glass, also known as electrochromic glass or dimming glass, is a material that can change its optical properties through external stimuli (such as electricity, light, heat, etc.). This material has a wide range of application prospects in the fields of construction, automobile, aerospace, etc. In recent years, with the advancement of technology, the performance of smart glass has been continuously improved. DMEA dimethylamine, as an important additive, has significantly enhanced the dimming performance of smart glass. This article will discuss in detail the application of DMEA in smart glass and its enhancement mechanism for dimming performance.

2. Basic principles of smart glass

The core principle of smart glass is to change its internal structure through external stimulation, thereby adjusting the transmittance of light. Common smart glass types include electrochromic glass, photochromic glass, and thermochromic glass. Among them, electrochromic glass is a common type, and its working principle is to change the redox state of the electrochromic material in the glass by applying a voltage to adjust the transmittance of light.

2.1 Working principle of electrochromic glass

Electrochromic glass is usually composed of a multi-layer structure, including a transparent conductive layer, an electrochromic layer, an ionic conductor layer, and an ion storage layer. When a voltage is applied, the material in the electrochromic layer undergoes a redox reaction, resulting in changes in its color and transparency. This process is reversible, and by changing the polarity of the voltage, the glass can be restored to its original state.

2.2 Working principle of photochromic glass

Photochromic glass changes its optical properties through light. When exposed to ultraviolet light, the molecular structure of the photochromic material in the glass changes, resulting in changes in color and transparency. After the light stops, the material will gradually return to its original state.

2.3 Working principle of thermochromic glass

Thermochromic glass changes its optical properties through temperature changes. As the temperature rises, the thermochromic material in the glass undergoes phase change, resulting in changes in color and transparency. After the temperature drops, the material will gradually return to its original state.
