Abstract
A composite enclosure component for an electronic device is disclosed. The composite enclosure component may include metallic nanoparticles, non-metallic nanoparticles, or a combination of these. The nanoparticles of the composite enclosure component may provide a hue, enhanced mechanical properties, or both.
Claims20
A portable electronic device comprising:
- a display;
- a camera assembly;
- and
- an enclosure enclosing the display and comprising:
- a housing defining a set of side surfaces of the portable electronic device;
- a front cover assembly positioned over the display and defining a front surface of the portable electronic device;
- and
- a rear cover assembly positioned over the camera assembly and defining a rear surface of the portable electronic device, the rear cover assembly comprising:
- a composite cover member comprising a set of metallic nanoparticles and a set of non-metallic nanoparticles embedded within a glass-based material, the set of metallic nanoparticles configured to absorb at least one wavelength of light in the visible spectrum;
- and
- a polymer coating disposed over an interior surface of the composite cover member, the polymer coating configured to reflect at least a portion of light transmitted through the composite cover member.

An electronic device comprising:
- a display;
- and
- an enclosure at least partially surrounding the display, the enclosure comprising a cover assembly including a composite cover member comprising:
- a glass-based material;
- a set of metallic nanoparticles dispersed within the glass-based material;
- and
- a set of non-metallic nanoparticles dispersed within the glass-based material.

A mobile phone comprising:
- a display;
- a camera assembly;
- and
- an enclosure enclosing the display and the camera assembly, the enclosure comprising:
- a housing;
- and
- a cover assembly coupled to the housing and including a composite cover member comprising:
- a matrix formed of a glass-based material having a concentration of a metal ranging from 2 mol % to 10 mol %;
- and
- a set of nanoparticles formed from the metal and embedded within the matrix, the set of nanoparticles formed from the metal configured to provide a chromatic color to the composite cover member and to impede crack propagation within the composite cover member.
