Cover Story: The paper discusses the possibility of using in situ generated nanofibrillar polymer nanocomposites as polymeric materials with triple shape memory, which, unlike conventional polymer blends with triple shape memory, are characterized by fully separated phase transition temperatures and strongest bonding between the polymer blends’ phase interfaces, which are critical to the shape fixing and recovery. The in situ generated nanofibrillar composites showed drastically higher values of strain recovery ratios, strain fixity ratios, faster recovery rate and better mechanical properties compared to the blend.
