Abstract
Abstract Pellicles of para-xylylene polymers are used as the sole support media for masses of objects supported thereon. The supported objects can be combined with the pellicle either during the formation of the pellicle or after the pellicle has been manufactured. The composite article is used wherever it is desirable to provide a support media which has as little detrimental influence as possible on the intended function of the supported object.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
127 words
An article of commerce which is a simulated rain field consisting essentially of an essentially flat film of p-xylylene polymer having a thickness of up to about 25,000 A and wholly supporting one or more discrete objects which are bonded thereto on at least one face thereof, said objects being in the form of encapsulated liquid droplets, the total surface area of said objects facing said film being less than the total surface area of the supporting face of said film, said supported objects being ohmically isolated with respect to non-supported objects; each of said objects having a particle size of up to about 5 millimeters and supported on said film so as to cover up to about 80 per cent of the surface of said field.
