Case Study

Anti-Corrosion Treatment of Anodized Aluminum Surface with Trimethoxypropylsilane

Bahareh Javanpour, et al. Journal of Applied Electrochemistry, 2022, 52(1), 67-83.

Double silane treatment of the anodized layer using two alkoxysilanes with different functional groups. The anodized samples were first silane treated with tetraethoxysilane (TEOS) sol, and then subjected to secondary modification treatment with trimethoxypropylsilane (TMPSi). The results show that two alkoxysilanes with different functional groups are compatible and improve overall corrosion resistance.
Silane treatment procedure
· First, prepare the sol starting solution with tetraethoxysilane (TEOS) and ethanol (EtOH). After an aging process for a day, the dip-coating technique was conducted using a dip coater adjusted at a 20 cm/min constant withdrawal rate. Coated samples had been dried under a controlled condition at 60-70 °C for 1 h to avoid cracking, and followed a heat treatment for 1 h at 300 °C for in an oven.
· As for the modifcation step, the sample was retreated by the trimethoxypropylsilane sol (TMPSi). Therefore, a sol was synthesized using distilled water and Ethanol in TMPSi: EtOH: water, 1:10:10 molar ratio adjusted in pH 2.3 by (0.1 M) HNO3. Likewise, the sample was immersed in the second sol (TMPSi sol) and then dried under the same condition. Ultimately, heat treatment lasted for 1 h at 150 °C.

Application of Trimethoxypropylsilane in the Preparation of Superhydrophobic Coating

Emarati, et al. Surface Engineering, 2019, 35(5), 456-465.

A two-step process was used to deposit a superhydrophobic TiO2/TMPSi (trimethoxypropylsilane) composite coating on AISI 316L stainless steel, which exhibited superhydrophobic properties with WCA = 160.1° and SA = 3.7° under optimal conditions.
· Electrophoretic coating of TiO2:
Electrophoretic deposition (EPD) of TiO2 nanoparticles from a colloidal suspension of TiO2 in acetylacetone by adding iodine.
· Modification by trimethoxypropylsilane:
First, a homogeneous solution of 95 vol.-% ethanol and 5 vol.-% of deionised water was prepared. Then by dropwise addition of acetic acid, pH of the solution was adjusted in the range of 5.5-6.5. While water and alcohol were being mixed by magnetic stirring, the TMPSi was gradually added to the container. Then, the solution was magnetically stirred for 10 min. The solution was aged for 24 h in the dark environment to complete the forming of silanol (Si-OH) bonds. While the chemical modifying solution was being stirred by a magnetic stirrer for 10 min, coated samples were immersed in the solution. The samples were removed from the solution and dried at room temperature with humidity less than 35% for 24 h.
