1. Core Working Principles
-
Solvent Release Mechanism:
-
Nano-encapsulation: Each microcapsule contains 0.5-2μL solvent, released gradually through fiber friction
-
Diffusion formula: Q=K·ΔP·t (Q=release amount, K=material coefficient, ΔP=pressure difference, t=time)
-
-
Structural Design:
-
Sandwich architecture: PE barrier layer (anti-evaporation) + dual-gradient fibers (absorption/release balance)
-
2. Materials Science Perspective
✅ Fiber Properties:
-
Polyester/nylon blend (0.3-0.8μm diameter)
-
Specific surface area >200m²/g (enhanced solvent loading)
✅ Solvent Formulations: -
Electronic grade: 99% IPA + 0.1% corrosion inhibitor
-
Medical grade: 75% ethanol + 0.5% glycerol (humectant)
