The core electronic property of this compound stems from the highly electronegative trifluoromethyl (-CF₃) group on its side chain. This group significantly reduces the molecule's polarization and imparts extremely low surface energy to the polymer. Although its bulk form is an excellent insulator, the introduction of the -CF₃ group enables the homopolymer or copolymer to exhibit outstanding hydrophobicity, oil repellency, high chemical stability, and excellent optical transparency (especially in the ultraviolet region). Additionally, the fluorinated structure brings lower dielectric constant and dielectric loss, making it highly promising for high-speed, high-frequency signal transmission applications.

In electronic applications, this compound is primarily used to prepare high-performance electronic protective coatings and low-dielectric materials. It is widely employed in ultra-hydrophobic, moisture-resistant, and anti-contamination coatings for printed circuit boards (PCBs) and precision electronic components, effectively protecting against moisture, flux, and chemical erosion. Meanwhile, its polymer is a key component in the preparation of low-dielectric constant (low-k) inner-layer insulation materials for chips or high-frequency circuit boards, helping to reduce signal transmission delay and crosstalk. Furthermore, in optical waveguides and LED packaging, TFEMA-based transparent, weather-resistant resins are also used to protect sensitive optical interfaces.
