摘要： A substrate is coated with a hydrophilic layer(s) or coatings(s) that includes, for example, amorphous carbon in a form of diamond-like carbon (DLC). In certain embodiments, the DLC inclusive layer may be doped with at least one polar inducing dopant (e.g., Boron, Nitrogen, and/or any other suitable polar inducing dopant) in order to make the layer more polar and thus more hydrophilic so as to have a lower contact angle υ (e.g., no greater than about 10 degrees in certain embodiments, and more preferably no greater than about 8 degrees).

摘要： This invention relates to thermoplastic interlayers for laminated safety glass with superior vacuum de-airing at elevated temperatures and superior tacking and edge sealing properties. The sheeting has surface pattern on at least one of the surfaces characterized by flat surfaces with substantially uninterrupted channels for air flow in at least two intersecting directions. The channels allow for rapid de-airing while the area roughness parameter ratio ARp/ARt in the range of 0.52 to 0.62, ARt being less than 32 νm, and area kurtosis less than 2.5, allow for ease of tacking of the interlayer onto glass and edge sealing after de-airing has been completed. Said surface pattern may also be superimposed onto a pattern which is generated by melt fracture or other means on at least one side to enhance de-airing and aid edge sealing.
