WebZein fibers were successfully fabricated via solution blow spinning (SBS) using acetic acid as solvent. Surface tension, viscosity and modulus of zein solutions were respectively determined by force tensiometer and rheometer. Increases of these properties were observed with an increase of concentration from 20% to 35% (w/w). WebFeb 28, 2024 · The surface tension of water is much higher than that of alcohol (flux), however, which prevents penetration of cavities. Further complicating matters, tap water itself contains ions that will themselves contaminate circuitry. Removing ions from water (“deionized water”) causes surface tension to increase.
