Course description and aims

Understanding the principle of experiments and the obtained meanings of the properties by the experiments is essential in material science and engineering.The learning of fundamental skills of chemical and physical measurement opeation is required for the correct and safe experiments. In this experiment course, the following topics will be covered: application of finite difference method for numerical analysis of heat transfer, comparative analysis of numerical result with direct temperature measurement and heat transfer visualization using infrared camera; measure the characteristics of PLLA with differential scanning calorimetry (DSC), wide-angle X-ray diffraction (WAXD) and dynamic mechanical analysis (DMA), understand the principal of those measurement, discuss the relationship between the micro-structure and thermal and mechanical (temperature- and frequency dependence) characteristics of it; experience the melt-processing of thermoplastic polymers, understand the relationship between process conditions, fiber structures and fiber properties through structure analyses and property measurements of synthetic fibers which were made in various conditions. The safety training programs for experiments will be also learned. The aims of this course are to make students to get the basics for organic and polymeric materials through the learning of experimental operations, principles, comparison between the theoretical and observed data, in order to improve their skills and understandings from the viewpoints of general education covering the wide area from the basics to the advanced research of science and engineering. Additionally, the number of students will be restricted by the limitations such as experimental space and so on. The learning quarters and orders could be also changed. Students can learn whole themes in Experiments of Organic and Polymeric Materials I, II and III in a different order, by taking all courses of Experiments of Organic and Polymeric Materials at 1st, 3rd and 4th quarters.

Student learning outcomes

By the end of this course, students will be able to:
1. have acquired fundamental skills of chemical and physical measurement operations, 2. understand the chemical reactions and analysis,
3. understand the meanings of measured properties and their principles,
4. understand the relation between the conditions of sample preparation and their properties, 5. understand the experimental methods, data analysis and discussion based on obtained data,
and learning the basics for more advanced experiments.

Competencies that will be developed

✔ Specialist skills Intercultural skills Communication skills ✔ Critical thinking skills ✔ Practical and/or problem-solving skills

Class flow

Students work in teams throughout this course and conduct a series of experimental themes. The learning quarters and orders could be also changed. Students can learn whole themes in Experiments of Organic and Polymeric Materials I, II and III in a different order, by taking all courses of Experiments of Organic and Polymeric Materials at 1st, 3rd and 4th quarters.The written report must be submitted by a specified date. Students must read the experiment text before the start of each experiment to ensure safety and smooth running.
