We fabricated a series of novel shape memory composites using natural Eucommia ulmoides rubber (EUR) and polybutene-1 (PB-1) as basic materials for the first time. The shape memory composites were prepared via simple physical blending and chemical crosslinking methods with co-continuous architecture and multiple shape memory behaviors. These composites and their preparation methods might be widely used in the field of heat shrinkable tubes. We studied the mechanical, thermal and shape memory properties of the composites, and proposed schemes to explain their dual and triple shape memory effects. In the EUR/PB-1 composites, both the crosslinking network of the composites and crystalline regions of PB-1 could function as the fixed domain, and the crystalline zones of EUR and PB-1 could act as the reversible domain individually or jointly. The composites exhibited excellent dual shape memory properties with blending ratios of 90/10 and 80/20, and good triple shape memory properties with blending ratios of 70/30 and 60/40.
