Characteristics and bending performance of electroactive polymer blend made with cellulose and poly(3-hydroxybutyrate)

► Cellulose/PHB blend prepared by solution casting was used as electroactive polymer. ► The bending displacement performance is improved compared with pure cellulose in room humidity condition. ► The humidity sensitiveness of the cellulose/PHB blend becomes less than pure cellulose. ► The durability of the cellulose/PHB blend becomes much longer than pure cellulose in room condition.
