The present invention relates to a solution or ink composition for fabricating high-performance thin-film transistors. The solution or ink comprises an organic semiconductor and a mediating polymer such as polyacrylonitrile, polystyrene, or the like or mixture thereof, in an organic solvent such as chlorobenzene or dichlorobenzene. The percentage ratio by weight of semiconductor:mediating polymer ranges from 5:95 to 95:5, and preferably from 20:80 to 80:20. The solution or ink is used to fabricate via solution coating or printing a semiconductor film, followed by drying and thermal annealing if necessary to provide a channel semiconductor for organic thin-film transistors (OTFTs). The resulting OTFT device with said channel semiconductor has afforded OTFT performance, particularly field-effect mobility and current on/off ratio that are superior to those OTFTs with channel semiconductors fabricated without a mediating polymer.

A surface treatment liquid capable of making a surface of a treatment target hydrophilic or hydrophobic without including a resin having a coating film formation property, and a surface treatment method using the surface treatment liquid. The surface treatment liquid includes a resin, a solvent and a strong acid having a pKa of 1 or less. The resin includes a functional group I that is at least one of a hydroxyl group, a cyano group, and a carboxyl group, and a functional group II that is a hydrophilic group or a hydrophobic group other than the functional group I.

A method is designed to prepare foamed, opacifying elements each having a target light blocking value (LBV.sub.T) of at least 3, using a textile fabric substrate with a light blocking value (LBV.sub.S). The LBV.sub.T-S difference is calculated; a foamable aqueous composition is chosen; a dry coating weight for the foamable aqueous composition (when foamed) is determined to form a single dry opacifying layer that is foamed, dried, and densified to provide a dry thickness at least 20% less than the original dry thickness. The single dry opacifying layer a has light blocking value that is equal to LBV.sub.T-S, 15%. The desired foamable aqueous composition can be chosen from a set of similar compositions to achieve the desired LBV.sub.T with the noted textile fabric substrate using suitable mathematical formula relating dry coating weight to light blocking value and a suitable data processor.
