Introduction

Choon Ki Lee is a prominent inventor based in Seoul, South Korea. He has made significant contributions to the field of biodegradable materials, holding a total of 7 patents. His innovative work focuses on developing materials that are both environmentally friendly and bioactive.

Latest Patents

One of his latest patents is for a biodegradable and bioactive glass-ceramic. This invention involves a unique fabrication method that combines a slowly biodegradable glass-ceramic with a highly biodegradable counterpart in a specific mixing ratio. This approach ensures that the bioactivity remains constant while controlling the biodegradation rate. The composition includes essential components such as calcium oxide (CaO), silica (SiO), boron oxide (BO), magnesium oxide (MgO), calcium fluoride (CaF), and phosphorus pentoxide (PO).

Another notable patent is a method for producing a polymeric sol of a calcium phosphate compound. This method results in a transparent and homogenized sol that exhibits excellent wettability and bioactivity. The sol-gel synthesis technique is employed to coat the polymeric sol onto a metal implant, followed by heat treatment to create a dense layer that is strongly bonded to the implant.
