AIST Stories No2

13Leading the way AIST!“By making slight modifications to a clay that exists in the natural world we came up with Claist, a “natural blessing” as it were. Because it’s merely earth, there are no associated environmental impacts during its manufacture, nor its disposal. By manufacturing practical products from this material born of a region’s natural environment that are of use to society, we can evolve businesses whereby the region’s raw material does not end up merely at the local product level. Through this, I feel that we can bring about a regional economic effect, as well as furnish workplaces for the region. I will continue to leverage the benefits of not only clay but various other natural materials such as minerals and wood, advance “blessed product creation” in new industries, and carry out product creation leading to true sustainability.”*6 Organic electronics: Electronics based on organic semiconductors made by deposition or coating of organic substances on plastic substrates. *7 Clayteam: A consortium with AIST at its core established as a forum for collaboration from various fields and industries in product creation through material development leveraging clay films and inorganic nanomaterials.inner layer polypropylene film can prevent the permeation of oxygen and extend the preservation of freshness as well as prevent changes in the ingredients from occurring. At present, pricing is higher than conventional packaging materials but if a cost reduction of more than half can be achieved, the potential is high for significant inroads to be made in this application.Application is seen as possible in areas such as sealants to prevent the leakage of refrigerant gas from heating and air-conditioning units and furthermore. coating materials that prevent rusting, and flame-retardant interior materials for buildings and vehicles. Currently, joint research and development is underway with companies in these various fields.The respective technology transfer situations vary depending on the product, from those in the planning stage through to those that are just prior to commercialization. 2003Gas barrier properties of clay film discovered2004Transparent clay film invented2006Water-resistant clay film invented2007Asbestos alternative gasket commercialized‌‌‌‌2010Clay for film applications commercialized‌‌‌Raw material clay for Kunimine Industries’ Kunipia M performance film2011年Self-healing gas barrier film developedContinuous production of thick films enabled AIST inaugurated a consortium known as the Clayteam*7 in 2010 in order to organically link these joint projects and promote R&D. Under the chairmanship of Ebina, approximately 50 corporations and associations are engaged in comprehensive research that gathers together manufacturing expertise.“What technologies should we bring together and in what manner in order to efficiently develop what we are targeting? AIST is tasked with major role as coordinator in this comprehensive development.”Moving forward, cost reductions will be pursued for clay raw materials, raw material pastes for films, and commodity films, and usage in a broader range of industries is anticipated for this new material that has emerged from the Tohoku region, headed by electronics and automotive and including, aerospace and power electronics.Development historyA visionof the futureClaist
