Abstract
There is disclosed an optically clear shear thickening fluid and a protection assembly comprising the optically clear shear thickening fluid. It further relates to uses of the optically clear shear thickening fluid in electronic devices, particularly in optical display devices. The optically clear shear thickening fluid includes: (a) a solid nanoparticle having an average particle size equal to or less than 100 nm; (b) at least one polymer; and (c) a liquid medium. The at least one polymer is substantially soluble in the liquid medium.
Claims20
An optically clear shear thickening fluid comprising:
- a solid nanoparticle having an average particle size equal to or less than 100 nm;
- at least one polymer;
- and
- a liquid medium,
- wherein the at least one polymer is substantially soluble in the liquid medium.
A method for producing a protection assembly, comprising steps of:
- (a) providing at least one polymer having a crosslinkable group;
- (b) dissolving the at least one polymer in a liquid medium to form a polymer solution;
- (c) dispersing a solid nanoparticle having an average particle size equal to or less than 100 nm into the polymer solution to form an optically clear shear thickening fluid (STF);
- (d) coating the shear thickening fluid on a first optically clear layer to form a STF layer;
- and
- (e) exposing the STF layer to an amount of curing energy to form a cured STF layer.
A method for producing a protection assembly, comprising steps of:
- (a) providing at least one polymer and a crosslinking agent;
- (b) dissolving the at least one polymer and the crossing agent in a liquid medium to form a polymer solution;
- (c) dispersing a solid nanoparticle having an average particle size equal to or less than 100 nm into the polymer solution to form an optically clear shear thickening fluid (STF);
- (d) coating the shear thickening fluid on a first optically clear layer to form a STF layer;
- and
- (e) exposing the STF layer to an amount of curing energy to form a cured STF layer.
