Super Hydrophobic Material
What is Super Hydrophobic Material?
A super hydrophobic material is a coating that mimics nature’s water-repellent surfaces (e.g., lotus leaves) by combining micro-nano rough structures with low-surface-energy materials, creating a surface where water forms beads with a contact angle > 150°, enabling efficient water repellency, self-cleaning, and protection against moisture, corrosion, and short circuits in electronic applications.
Industry Applications
Electronic Lock
200h salt spray resistance, 168h extreme temperature (-40℃~80℃), waterproof and anti-condensation.
Earphone/Smartwatche
Resists sweat spray for 2h, 50m waterproof, stable in high-temperature & humidity (95%RH).
Motherboard/Switche
Anti-corrosion and anti-condensation for circuit safety in harsh environments.
Core Technical Advantages
Industry Breakthrough: The first scalable super hydrophobic coating for electronics, verified with Huawei, suitable for PCB boards.
Performance Data: Contact angles of 157°/158° on copper/tin plates, remaining > 150° after 100 days of water immersion.
| Property | Super Hydrophobic Coating | Traditional Conformal Coating |
|---|---|---|
| Waterproofing | Water droplets bounce (contact angle > 160°), durable for 100+ days | Depends on density, fails after long immersion |
| Anti-Short Circuit | Isolates moisture/liquids, 1.5x better than 3M conformal coating | Prone to short circuits due to saltwater infiltration |
| Corrosion Resistance | Withstands 2000h+ salt spray, stable in pH2-12 solutions | Typically < 1000h salt spray resistance |
| Self-Cleaning | Lotus-effect, dust easily removed | No self-cleaning function |
| Ease of Application | Dip/spray coating, no masking needed, surface-dry in 3-5 mins | Complex process with masking required |
| Thermal Conductivity | 3.3W/mK (1 order higher than conformal coatings) | Poor heat dissipation in polymer materials |
| Eco-Friendly | Non-toxic, non-flammable, odorless | Contains benzene/solvents, toxic volatiles |
