This invention relates to a supported polymer heterostructure and methods of manufacture. The heterostructure is suitable for use in a range of applications which require semiconductor devices, including photovoltaic devices and light-emitting diodes.

The present invention relates to functionalized polymers including a poly(phenylene) structure. The structure can include any useful modifications, such as the inclusion of one or more reactive handles having an aryl group. Methods and uses of such structures and polymers are also described herein.

The present disclosure relates to a carbon fiber dome including at least two carbon fiber prepreg layers, and the at least two carbon fiber prepreg layers include at least two types of carbon fiber materials. The present disclosure further relates to a method for manufacturing the carbon fiber dome, including: impregnating at least two types of carbon fiber materials with a prepreg resin to form at least two carbon fiber prepreg layers; and laminating the at least two carbon fiber prepreg layers after being impregnated. The carbon fiber prepreg is used to substitute the aluminum foil, thus, the strength is improved, the thickness is reduced and the sounding quality is improved, further, the carbon fiber material prepreg layers tightly adheres to each other to form an integrated structure, so that splitting of layers is avoided, and the dome has better water-proof effect and longer service life.

A composite radius filler material is provided. The composite radius filler includes a resin, a first group of fibers dispersed within the resin, and a second group of fibers dispersed within the resin. The first group of fibers has a first length configured to facilitate orientation in a longitudinal direction. The second group of fibers has a second length that is shorter than the first length, with the second group of fibers configured to facilitate random orientation in a transverse direction.

Described herein are anionic phenylene oligomers and polymers, and devices including these materials.
