Outline of Final Research Achievements

Plant cuticle is an ideal bio-based packaging material with well-balanced performance. This study deals with new biomimic design of artificial cutin and cuticle. A network polymer consisting of soft segment derived from plant oils such as dimer acid and ricinoleic acid was synthesized as artificial cutin. Cellulose sheet from reactive bacterial cellulose and amorphous cellulose was used for lamination with artificial cutin to produce artificial cuticle.
