The invention pertains to certain perfluorinated thermoplastic elastomers suitable for being processed through additive manufacturing techniques, thanks to their surprising ability to possess better processability (notably more significant shear thinning at processability temperature) than corresponding perfluorinated thermoplasts, which possess similar product profile and hence performances, offering hence advantages in throughput and part design accurate control, containment of degradation, reduction of fumes, and yet delivering parts with outstanding chemical resistance.

The invention discloses a separator with a wide temperature range and a low heat shrinkage and a method for preparing the same. The invention belongs to the field of electrochemistry. The separator of the invention includes: an irradiation crosslinked fluoropolymer A with a melting point above 150° C. and/or a polymer B containing a benzene ring in its main chain; an ultrahigh molecular weight polyethylene having a molecular weight of 1.0×10.sup.6-10.0×10.sup.6, and a high density polyethylene having a density in the range of 0.940-0.976 g/cm.sup.3; the temperature difference between pore closing temperature and film breaking temperature of the separator is 80-90° C., preferably 85-90° C., the heat shrinkage of the separator is 2.0% or less. The separator of the invention has a high temperature difference between film breaking temperature and pore closing temperature, and a low heat shrinkage; when the separator of the invention is used in an electrochemical device, the reliability and safety of electrochemical device can be effectively improved.

Disclosed is a molded article including a modified fibroin and a water resistance-imparting material. The modified fibroin and the water resistance-imparting material may be covalently bonded.

A method for determining pane thicknesses and a wedge angle of a coated windshield for a projection arrangement of a head-up display. A wedge angle and a combination of glass thicknesses are determined by means of which the glass ghost image and the layer ghost image are optimally reduced. The method proceeds from a starting thickness of the two glass panes of the windshield for which that wedge angle is determined, in an iterative process, that represents an optimal compromise between the minimization of the glass ghost image and the minimization of the layer ghost image. Then, the glass thicknesses are determined varied within a specified range for each combination of the optimal wedge angles. Thus, it is possible, iteratively, to identify that combination of glass thicknesses that results in the least occurrence of ghost images, in addition to the associated optimal wedge angle.

An embodiment relates to a sheet comprising an acrylic resin layer and a fluorinated polymer resin layer directly formed on one surface of the acrylic resin layer; a laminated steel plate comprising the sheet; and a manufacturing method therefor.
