AI Technical Summary

Benefits of technology

This patented describes different types of materials that may be added into plastic compositions or other products like paints, coatings, adhesives, etc.. These new materials help increase their physical strength, flexibility, durability, waterproofness, chemical resistivity, electrically insulating property, and environmental friendliness compared to existing ones.

Problems solved by technology

This patents discuss various technical problem addressed in this patented text relating to improving the mechanical property of plastic compositions used in electronics devices like mobile phones, computers, servers, radios, televisions, displays, sensors, optical communication equipment, antennas, filters, and others. These applications involve use of these types of materials because they must maintain good conductivity even when exposed to harsh environments without losing functionality over longer periods of time. To achieve this goal, the inventory rate of new ones should decrease, resulting in increased costs associated with manufacturing processes. Therefore, the focus lies towards finding improved materials called low dielecrosielectronic (low dielectrification) liquids containing specific functional groupings within the framework structure.
