Full Program Details (Please see below if you are interested in the specifics) ────────────────────────────────────────────── [Lecture Abstract] This lecture summarizes the methodologies for polymer grafting reactions on the surfaces of nanocarbons such as carbon nanotubes and graphene, as well as nanoparticles such as silica. It then explains, with specific examples, the synthesis and experimental methods for polymer-grafted nanoparticles based on functional groups introduced to the particle surface, along with surface evaluation techniques. Furthermore, it discusses the imparting of various functions to nanoparticle surfaces through the grafting of antibacterial polymers and the immobilization of bio-repellent substances. It also covers the immobilization of nanocarbons on carbon material surfaces, its potential as a new material, and dispersion control technology for nanoparticles via surface grafting. Additionally, it discusses the application of nanoparticle grafting technology to the surface hydrophobization of cellulose nanofibers and cellulose nanocrystals.
