POLYMER PARTICLE CONTAINING MAGNETIC MATERIAL, MEDIUM FOR SENSORS, AND SENSOR DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18175036 titled 'POLYMER PARTICLE CONTAINING MAGNETIC MATERIAL, MEDIUM FOR SENSORS, AND SENSOR DEVICE
Simplified Explanation
The patent application describes a polymer particle that contains magnetic material.
- The particle has three layers: a core, an intermediate layer, and a polymer layer.
- The core contains magnetic fine particles with an average diameter between 5 nm and 30 nm.
- The intermediate layer has a lower concentration of magnetic fine particles compared to the core.
- The polymer layer covers the intermediate layer.
- The thickness of the intermediate layer is between 5% and 60% of the radius of the particle.
Original Abstract Submitted
A polymer particle containing magnetic material includes a core, an intermediate layer, and a polymer layer. The core includes magnetic fine particles having an average diameter of 5 nm or more and 30 nm or less. The intermediate layer is located outside the core and has a lower concentration of the magnetic fine particles than the core. The polymer layer covers the intermediate layer. A thickness of the intermediate layer is 5% or more and 60% or less of a radius of the polymer particle containing magnetic material.
