| Outline and Purpose of the Course | The following contents are presented. Relationships between usages of polymeric composite materials and environmental issues, polymer alloys, general biomass/plastics composites, polymeric nanocomposites (matrix materials: synthetic resins, plasticized wood; fillers: nanoclay, cellulose nanofiber, nanosilica), adhesion and adhesives. | |||
| Course Goals | The students can understand the composite materials deeply and obtain knowledge and ability concerning application of various plant biomasses to composite materials. | |||
| Schedule and Contents |
1. Biogradable and biomass plastics: Topics studied include their definitions, their roles in society, biogradable assessment and biomass measurement and their certification systems, and life cycle assessment. (2 sessions) 2. Polymer alloys: Students will study examples of the development of high-performance polymer alloys and understand the relationship between the performance of polymer alloys and polymer miscibility and the content of plant-derived ingredients. (3 sessions) 3. Biomass/plastic composite materials: Students will enhance their understanding of the physical characteristics of plant fibers, which are used as fillers and reinforcements, and learn about wood-plastic composites (WPCs), cellulose nanofiber reinforced polymer composites, etc. (3 sessions) 4. Inorganic/plastic composite materials: These lectures will outline the characteristics of inorganic fillers with a focus on clay, and introduce students to clay-based nanocomposites. (3 sessions) 5. Adhesion and adhesives: These sessions will help students understand what adhesion is and the different categories of adhesives and the basic requirements of adhesives, as well as the elementary process of adhesion and problems associated with the process. Students will also familiarize themselves with surface chemistry, general principles of surface tension, the Orowan-Polanyi equation on theoretical cohesive strength, and the theoretical cohesive strength of Lennard-Jones solids. (2 sessions) 6. Intermolecular force and adhesion: Students will learn about primary bonding (chemical bonding) and secondary bonding. In particular, emphasis will be placed on the Van der Waals force, which consists of orientation, induction, and dispersion forces, and the effects of molecular cohesion on adhesion. (1 session) Feedback: Time will be set aside to answer questions regarding the lectures to help students understand the course content. |
