TWO-DIMENSIONAL NANOSHEET AND PREPARATION METHOD THEREFOR

Resumen de: US20260285701A1

0000 A preparation method for a two-dimensional nanosheet. The method includes: performing a calendering treatment on non-Van der Waals layered crystal particles, and then performing mechanical exfoliation, so as to obtain a two-dimensional nanosheet. Mechanical exfoliation is commonly referred to as a scotch tape method, and mechanical exfoliation may only be performed by using an adhesive tape (sometimes, the assistance of an interposer is required) when the interlayer interaction of a bulk material is dominated by a weak van der Waals force; however, there is significant electron density overlapping between layers of many functional materials with layered stacked crystal structures, and the electron density overlapping forms a non-Van der Waals structure, which cannot be directly exfoliated by using the adhesive tape. In the present method, few-layer or even single-layer structures of various non-Van der Waals layered crystal materials are successfully obtained for the first time by means of a calendering pretreatment combined with mechanical exfoliation; in addition, a new physical phenomenon can be observed in an exfoliated two-dimensional crystal.

FREQUENCY SELECTIVE METAMATERIAL FOR PROTECTIVE ENCLOSURES

Resumen de: US20260293072A1

The present disclosure provides a protective enclosure for electronic systems. The enclosure comprises a polymer-containing matrix and a metamaterial incorporated into the matrix. The metamaterial is tuned to a specific permittivity or permeability to absorb or reflect a particular frequency. The protective enclosure may be used to create a safe inner environment for electronic components while facilitating uninterrupted wireless communications to/from the outer environment. Additionally, the protective enclosure may be used to protect against electromagnetic interference. In particular, shielding metamaterials are configured individually or in combination to specifically shield (via reflection, absorption, etc.) against relatively wide bands of electromagnetic frequencies, while transparent metamaterials are configured specifically to pass electromagnetic signals within narrow bands of frequencies. This new approach resolves and vastly improves current shield solutions, such as Faraday cages. For example, tuned metamaterials may be configured across a variety of preconfigured frequencies, and can be constructed of lightweight materials.
