Electronic assemblies, especially one containing volatile memory, used a flexible membrane with conducting lines which acts as an intrusion sensor against chemical and mechanical attacks. The lines are fabricated from inherently conducting polymers which are solution processed and directly patterned. The material was applied to a flexible polymer film by spin coating and patterned by application of a resist, followed by exposure / development of the resist and transferring the image into the polyaniline by reactive ion etching techniques. The conducting lines have high conductivity, tranparency properties which made them difficult to detect and possess excellent adhesion to the substrate film, as well as to the potting material which enclosed the structure. They also offered lightweight advantages over conventionally filled materials. These materials can also be used in conjunction with conventional conductor materials to further enhance protection against intrusion by sophisticated mechanical means.

Porous films with straight pores oriented normal to the plane of the films are produced through solution processing techniques. The production takes advantage of inorganic-surfactant or inorganic-polymer co-assembly and a patterned substrate. The patterned substrate, which is also produced via solution phase self-assembly, forces vertical orientation in a hexagonal cylinder system with no practical limits in substrate size or type. This provides a route to vertically oriented inorganic pores with a pitch ranging from 3 nm to over 15 nm and pore sizes ranging from 2 nm to over 12 nm. The size is tuned by choice the choice of organic templating agents and the deposition conditions. The pores can be produced with or without a capping layer which can be used to seal the nanopores.

Polymer binders, e.g., crosslinked polymer binders, have been found to be an effective film component in creating high quality transparent electrically conductive coatings or films comprising metal nanostructured networks. The metal nanowire films can be effectively patterned and the patterning can be performed with a high degree of optical similarity between the distinct patterned regions. Metal nanostructured networks are formed through the fusing of the metal nanowires to form conductive networks. Methods for patterning include, for example, using crosslinking radiation to pattern crosslinking of the polymer binder. The application of a fusing solution to the patterned film can result in low resistance areas and electrically resistive areas. After fusing the network can provide desirable low sheet resistances while maintaining good optical transparency and low haze. A polymer overcoat can further stabilize conductive films and provide desirable optical effects. The patterned films can be useful in devices, such as touch sensors.

Directly on this treated surface, a hydrophilic layer is applied, which hydrophilic layer contains a non-crosslinked hydrophilic polymer having carboxylic acid side chains.

The optical downshifting layer can be applied as a low cost solution processed film composed of highly absorbing and emissive quantum dot heterostructure nanomaterial embedded in an inert matrix to improve the short wavelength response of the photovoltaic material. The enhanced efficiency provided by the optical downshifting layer permits advantageous modifications to the solar cell platform that enhances its efficiency as well.
