摘要:
The invention concerns an electrowetting device comprising first and second immiscible fluids, the liquids being sealed within a structure comprising a cap portion, a base portion, a gasket formed of a first material positioned between a first contact surface on said cap portion and a second contact surface on said base portion, and a first film formed of a second material between said gasket and one of said first contact surface and said second contact surface.
摘要:
The invention is directed to polymerizable vinyl compounds having halogenated aromatic groups and to a method of synthesizing such compounds. In particular, the invention is directed to polymerizable aromatic vinyl compounds wherein, except for the vinylic hydrogen atoms, aromatic C—H bonds are replaced by C—X bonds, where X is a halogen or other selected substituent having a de minimus number, if any, of C—H bonds; for example, without limitation, highly fluorinated fluoroalkanes. In addition, the compounds of the invention have a de minimus number, if any, of N—H and O—H bonds.
