The invention provides a structural base that includes a coating film on at least a portion of the surface thereof, the coating film having a difference between the maximum film thickness and the minimum film thickness of not more than 1000 ?. A method of the invention produces such structural bases. The coating film includes a copolymer including a repeating unit containing a group represented by formula (a), and a repeating unit containing a group represented by formula (b):

##STR00001##

wherein U.sup.a1, U.sup.a2, U.sup.b1, U.sup.b2, U.sup.b3 and An.sup.? are as defined herein.

The present invention is directed towards a moisture resistant radiation detector core assembly which was constructed by first assembling the photon-electron conversion layer, integrated circuit and the connection elements between and then encapsulating the whole assembly. This provides improved moisture barrier properties, since the encapsulation also covers the connection elements and does not have to be opened to apply the electrical connections, as is done for known radiation detector core assemblies.

The present invention provides a method of forming paracyclyophane containing disulfide functional group. The paracyclophane is prepared by adding 3,3-dithiodipropionic acid (DPDPA) and N-ethyl-N-(3-(dimethylamino)propyl)carbodiimide (EDC) into 4-aminomethyl [2,2] paracyclophane. The present invention further provides a chemical film and a method of forming the same. The chemical film contains poly-p-xylylene with disulfide functional group and is formed on a substrate by a chemical vapor deposition process.
