Embodiments of the present disclosure generally relate to housings for, e.g., memory devices and electronic devices, and to processes for forming such housings. In an embodiment, an article for housing at least a portion of an electronic device is provided. The article includes a first component comprising a thermoplastic and a biodegradable filler or polymer, and a second component disposed on at least a portion of the first component, the second component comprising a plurality of layers. The article has a scratch visibility load of about 200 gms or more, an electrostatic discharge static voltage of about 100 V or less, a thermal conductivity of about 0.28 W/mK or more, or combinations thereof.

Power generators that incorporate porous electric generation layers composed of mechanoradical-forming polymers are provided. Also provided are methods for using the generators to convert mechanical energy into and electrical signal to power electronic devices. The porous electric generation material includes an organic polymer that forms free radicals when covalent bonds are homolytically ruptured upon the application of a compressive force to the porous structure.

An object of the present invention is to provide a highly versatile master batch for producing a fiber-reinforced resin composition with high strength even when a highly hydrophobic resin is used as a resin for dilution (a resin that constitutes a fiber-reinforced resin composition). The master batch contains AcylMFs (A), a Pm (B), and a Com (C) and is for use in the production of a fiber-reinforced resin composition by mixing with a Pd (D), wherein the AcylMFs (A), Pm (B), Com (C), and Pd (D) satisfy the following conditions: (a) the AcylMFs (A) have an SP.sub.acylmf of 10 or more; (b) the Pm (B) has an SP.sub.pm of 9 to 15, and the SP.sub.pm is equal to or greater than the SP.sub.pd of the Pd (D); and (c) the Com (C) has an SP.sub.com equal to or less than the SP.sub.acylmf of the AcylMFs (A).
