The present disclosure is directed to dielectric elastomeric composites that include a retainable processing membrane, an elastomer material, and an electrically conductive material. The elastomer layer may be partially imbibed into the retainable processing membrane. The retainable processing membrane may be porous. The retainable processing membrane is compacted in the transverse in direction, machine direction, or in both directions prior to the application of an elastomer material and an electrically conductive material. The compaction of the retainable processing membrane may form structured folds or folded fibrils in the membrane, giving the retainable processing membrane a low modulus and flexibility. In some embodiments, the dielectric composites are positioned in a stacked configuration. Alternatively, the dielectric elastomeric composites may have a wound configuration. The dielectric composites have a total thickness less than about 170 μm. The dielectric elastomeric composites may be used, for example, in dielectric elastomer actuators, sensors, and in energy harvesting.

The thick polyimide-based carbon film with high thermal conductivity has a thickness greater than 100 μm and an in-plane thermal conductivity of even reaching 1700 W/mK or above.

Due to the increased glazed area of modern vehicles, especially the large panoramic glass roofs, we have seen a substantial growth in the use of anti-reflective coatings. Unfortunately, these types of coatings accentuate fingerprints and smudges. The invention provides an automotive glazing which is substantially resistant to fingerprints, and a method of manufacture thereof through the application of an anti-fingerprint coating based on low surface energy silanes.

The photochromic helmet visor includes a transparent piece, an adhesive layer attached to the transparent piece, a flexible base layer attached to the adhesive layer, a self-repairing layer attached to the flexible base layer, and a number of photochromic elements integrated with the flexible base layer or the self-repairing layer. The self-repairing layer includes a. PU layer and a. Siloxane layer attached to the PU layer. The photochromic elements are integrated with the flexible base layer or the self-repairing layer. The flexible base layer is made of PU, TPU, PVC, or PET, and may be tightly and smoothly joined to the transparent piece along with the adhesive layer. The self-repairing layer allows self-repairing to scratches or abrasions under a high temperature, thereby preventing the malfunction of the photochromic elements out of wear and usage and the resulted constant replacement, and enhancing the visor's durability.
