Title: Innovations by Inventor Ching-Hohn Len
Introduction
Ching-Hohn Len is a notable inventor based in Taipei, Taiwan. He has made significant contributions to the field of materials science, particularly in the development of innovative wound dressing materials. With a total of two patents to his name, Len's work showcases the intersection of medical applications and advanced polymer chemistry.
Latest Patents
Len's latest patents include a novel method for the preparation of easily stripped off temporary wound dressing materials. This method involves the successful grafting of N-isopropyl acrylamide (NIPAAm) monomer onto non-woven cloths through copolymerization. The process is initiated by gamma-ray irradiation, which activates the surface of the non-woven cloth. The resulting dressing material retains its lower critical solution temperature (LCST) even after grafting, allowing for easy removal without damaging the tissue. This innovative approach has significant medical applicability.
Another patent by Len focuses on the synthesis of poly(L-leucine). This method allows for the creation of poly(L-leucine) from L-leucine-N-carboxy anhydride in the solid state, using gamma-ray irradiation without any initiator or solvent. The entire synthetic process is remarkably simple, yielding a 100% polymerization rate. Poly(L-leucine) is recognized as one of the best materials for temporary wound dressing, highlighting Len's contributions to medical materials.
