I used methylcyclohexane/ ethylcyclohexane / n-butyl acetate mixed solvent to dissolve thermoplastic SBS & terpene resin. The mixture is then poured onto a glass substrate. After solvent volatilization, a large number of pores caused by trapped bubbles remained on the surface of SBS membrane. Is there any effective way to get rid of the bubbles? Is NIPS (Nonsolvent Induced Phase Separation) the right direction to explore?
Dear Sheng Lu,
You could put your samples into a vacuum oven or a vacuum chamber to get rid of bubles before your pouring your liquid on the substrate. Sometimes the bubbles could be gone from your samples if you put them under a fumehood for a number of hours.
In addition to the vacuum, yoi can use ultrsonic degassing for the whole mixtrue bedore castinf
