Adhesion promotion for e-paper vapor barriers

The passive e-paper assembly of claim 8, comprising:

• a second adhesion-promoting layer interposed between the airborne-charge receiving layer and the moisture vapor barrier, the second adhesion-promoting layer comprising at least one of:
• a hybrid material including at least one inorganic functional group and at least one organic functional group;
• and
• an organic polymer material.

An adhesion-promoting element comprising:

• an organic polymer layer to be interposed between a charge-transmissible, moisture vapor barrier layer and a first side of a charge-responsive, re-writable media layer of a flexible, passive e-paper assembly,
• wherein the moisture vapor barrier comprises a flexible inorganic material,
• wherein the organic polymer layer comprises a first ingredient comprising a silicone acrylate, silicone epoxy, alkyl acrylate, alkyl epoxy, and combinations thereof, and the organic polymer layer comprises a second ingredient comprising a dipentaraerythritol penta-hexacrylate material,
• wherein the adhesion-promoting element is to permit migration of charges from an airborne-charge receiving layer and the moisture vapor barrier layer through the inorganic polymer layer to the charge-responsive, re-writable media layer.

A method of manufacturing comprising:

• performing in a roll-to-roll arrangement:
• applying, onto a first side of a charge-responsive re-writable media layer of a flexible passive e-paper assembly, a first adhesion-promoting layer comprising comprises an electrical resistivity between about 108 and about 1013 Ohm-cm;
• and
• applying, onto the first adhesion-promoting layer, a charge-transmissible moisture vapor barrier layer which comprises a flexible inorganic material.
