basic information
**Lecture 1: Purpose of the Presentation** This presentation outlines the key points of optimal material design and molding processing of carbon fiber reinforced plastics (CFRP), as well as the considerations for selecting materials for CFRP products. It will introduce the technical points of molding processing categorized by application. Additionally, it will discuss the latest topics in molding processing technology. **Lecture 2: Purpose of the Presentation** This presentation summarizes the methodology for grafting polymers onto the surfaces of nanocarbons such as carbon nanotubes (CNT) and vapor-grown carbon fibers (VGCF). It will then introduce various polymer grafting reactions based on functional groups introduced onto the surfaces of CNT and VGCF. Furthermore, it will discuss graft reactions utilizing the radical trapping properties of CNT and VGCF surfaces, as well as graft reactions in dry systems without solvents. The presentation will also cover the functionalization of polymers through grafting to impart antibacterial and flame-retardant properties, along with the characteristics of polymer-grafted CNT and VGCF. **Lecture 3: Purpose of the Presentation** When carbon fibers (CF) are oxidized at the electrode, hydroxyl groups can be introduced onto their surfaces (CFOH). This CFOH is not only rich in hydrophilicity but also has a wide range of applications, including in fiber-reinforced plastics (FRP), Ni-H batteries as an anode, interlayer insulating films, and drug delivery systems (DDS).
