| Outline of Final Research Achievements |
Frost generation on the heat exchangers of household refrigerators and other equipment impairs the freezer function, and heaters are used to defrost the equipment, resulting in unnecessary energy consumption. We have developed a method of creating microplastic texturing to prevent frost generation on surfaces, and have created a texturing with improved thermal conductivity by blending a carbon-based powder substance. We found that microplastic texturing can be created by agglomerating and solidifying polyvinyl chloride (PVC) with 1.0 vol.% carbon black (CB) in a solvent under an alternating electric field.

| Academic Significance and Societal Importance of the Research Achievements |
NEXT11やBRICsを代表とする人口増加・エネルギ消費量増加が著しい諸国にとって，冷蔵庫を各家庭が持つことは豊かさを意味することから，人々の歩みを止めることはできない．消費する電力増加は爆発的であり，各家庭で消費されるエネルギ総量の約1%が除霜に用いれれている．このような無駄なエネルギをいかに削減していくかが今後の社会に求められる．本研究で取り組んだマイクロプラスチックテクスチャによる高熱伝導性表面の創製は，あらゆる熱交換器にも使用可能で，着霜・着氷防止を達成可能な点に社会的意義がある．
