Curable Composition for Nano-Fabrication

EX1)—47 parts 3,4-Epoxycyclohexylmethyl 3,4-epoxycyclohexanecarboxylate (EHEHC) (expanding monomers), 50 parts isobornyl acrylate (IBOA) (monoacrylate monomers), 2.5 parts diphenyliodonium hexafluorophosphate (DPIPF) (photoinitiator), 0.5 parts 2-isopropylthioxanthone (ITX) (photosensitizer), and 1 part surfactant fluorinated surfactant FS2000M1 made by Wonda Science were combined to form a curable composition. Each of the components are weighted on a balance and placed into an opaque bottle. Next, the components in the bottle are vortex mixed for 1 min and then left on a roller mixer for about 8 hours to form the curable composition.

EX2)—15 parts 1,4-Cyclohexanedione bis(ethylene ketal) (CHDB) (expanding monomers), 85 parts IBOA, 2.5 parts DPIPF, 0.5 parts ITX, and 1 part surfactant were prepared using the same method as in Example 1.

EX3): 79 parts Spiro[1,3-benzodioxole-2,2′(3′H)-furan], octahydro-, (T1, shown below) (expanding monomers), 19 parts of neopentyl glycol diacrylate, 0.9 parts DPIPF, 0.2 parts ITX, and 1.6 part surfactant were prepared using the same method as in Example 1.
