40Functional Polymer ScienceToshiki KoyamaAssociate ProfessorDeveloping thin, lightweight wearable fuel cells to supply power to robots and power suitsDepartment of Chemistry and MaterialsI am pursuing research into functional polymer membranes and nanofiber materials such as vaporization membranes for micro fuel cells that use neat methanol as fuel, self-humidification layers for H2/O2 fuel cells, carbon nano-paper as nano-porous gas diffusion electrodes, and nickel nano-paper for alkaline fuel cells using thin electrolyte membranes.Associate Professor Koyama took his current position in 1998 after serving in the Faculty of Textile Science and Technology at Shinshu University as an assistant professor and senior assistant professor. His area of research is physical chemistry related to the development of functional polymer materials and devices inspired by the movement of electrons and ions in living organisms.My lab is working to develop materials that will make possible more compact fuel cells that are both thinner and lighter. Wearer fuel cells would have numerous applications, including as power supplies for robots and power suits.Outlook for researchMany graduates go on to complete master's programs, after which they usually nd employment at companies involved with chemical materials, organic electronic materials, and electronic devices.Outlook for students after graduationA student uses an evaluation device to check the power-generating properties of fuel cells built with materials developed in the lab.This exible fuel cell with a thickness of 4 mm was formed from an array of six cells.We developed this carbon nanoweb (CNW) electrode with a diameter of 150 nm.Functional Polymer ScienceCreating high-function fibers to facilitate safer and more comfortable lifestylesDepartment of Chemistry and MaterialsFiber is a material that is essential in our daily lives, and I am pursuing research to make fiber even more useful. Currently, my lab is focusing on research to make fiber stronger (high performance) and to add conductive or antibacterial properties (high functionality) by combining numerous types of different materials.Yasuo GotohAssociate Professor Gotoh took his current position in 2007 after serving in the Faculty of Textile Science and Technology at Shinshu University as an assistant professor. His area of research is ber and polymer material science, and he is currently focuses on research into the properties of compound materials and high-polymer solids that combine organic and inorganic materials.When used in the bodies of moving vehicles such as aircraft and cars, these bers can reduce weight, improving fuel eciency and leading to energy savings. Improving the performance and functionality of ber is an area of research that contributes to the future of humanity.Outlook for researchMany graduates are employed by chemical and material companies. They also nd employment at non-ber-related companies when those companies handle bers.Outlook for students after graduationAssociate ProfessorHere, ber is being stretched on a heating plate. This process increases the strength of the ber by a factor of 10.Polymers are melted in a solution to prepare the spinning solution that serves as the raw material for ber.Direction ber travels
