Problems solved by technology

However, as far as the currently developed artificial bone material is concerned, it is necessary to perform replacement surgery every 10 to 15 years due to the separation problem caused by the continuous stress shielding phenomenon during repeated use
According to the survey, the cost of the first operation of this type of operation is usually more than 45,000 US dollars, and the second operation costs more than 74,000 US dollars, which brings a burden to the patient

Description

【Technical field】 [0001] The present invention relates to an organic / inorganic composite material using boron nitride. 【Background technique】 [0002] In recent years, organic-inorganic composite materials used in various materials have been required to have high physical properties. Since the mid-1990s, research on the development of new concept materials with high physical properties has been continuously carried out. At present, it is actively trying to integrate with nanotechnology. combined. [0003] Among them, two-dimensional nanostructure materials have a uniform planar shape, and their thickness consists of one or more layers of atoms. Recently, one of the most active researches in the field of chemistry and materials is the study of two-dimensional nanostructure materials, and, Its research topics are also diversified with the integration of electronics, machinery and biotechnology. [0004] Boron nitride (BN) material, which has attracted much attention, has sim...
