A writing feel improving sheet comprising a base material and a writing feel improving layer with which a touch pen is brought into contact, wherein when a touch pen having a pen tip of 0.5 mm diameter is used to bring the pen tip into contact with a surface of the writing feel improving layer with which the touch pen is brought into contact and the touch pen is then linearly slid at a speed of 1.6 mm/second while applying a load of 200 g to the touch pen and maintaining an angle formed between the touch pen and the surface at 45°, a difference between a maximum value and a minimum value of frictional force generated between the pen tip and the surface is 80 mN or more and 300 mN or less, wherein the frictional force is measured between a point at which a sliding distance is 10 mm and a point at which the sliding distance is 100 mm. The writing feel improving sheet makes it possible to well reproduce the writing feel experienced when writing on paper with a ballpoint pen.

Disclosed are a binder composition, a slurry composition, and a method of coating the surface of a metal with a superabsorbent polymer. Even when the slurry composition contains a large amount of the superabsorbent polymer, the low viscosity thereof can be maintained, thus enabling the uniform coating of the surface of the metal with the superabsorbent polymer. Also, even when a plurality of humidification-drying cycles is repeated in the coating process, no detachment occurs, and thus the superabsorbent polymer can be applied to various fields.

A coating composition includes an additive composed of a cellulosic powder which includes cellulose acetate, the cellulosic powder having a maximum particle size equal to or less than 2,000 microns; and at least one constituent mixed with the additive. The additive has 0.01 to 20 wt % based on a total amount of the coating composition being 100 wt %. The coating additive is mixed in the composition to modify gloss, surface durability, texturing, and/or haptic properties.

The present disclosure relates to a copper-clad laminate that may include a copper foil layer and a dielectric coating overlying the copper foil layer. The dielectric coating may include a resin matrix component, and a ceramic filler component. The ceramic filler component may include a first filler material. The dielectric coating may have an average thickness of not greater than about 20 microns.

Parts made by additive manufacturing are often structural in nature, rather than having functional properties conveyed by a polymer or other component. Printed parts having piezoelectric properties may be formed using a composite filament comprising a plurality of piezoelectric particles dispersed in a thermoplastic polymer. The composite filaments may be formed through melt blending and extrusion. The composite filament is compatible with fused filament fabrication and has a length and diameter compatible with fused filament fabrication, and the piezoelectric particles are substantially non-agglomerated and dispersed along the length of the composite filament. The piezoelectric particles may remain substantially non-agglomerated when dispersed in the thermoplastic polymer through melt blending. Additive manufacturing processes may comprise heating such a composite filament at or above a melting point or softening temperature thereof to form a softened composite material, and depositing the softened composite material layer by layer to form a printed part.
