Influence rules of reinforced materials on the properties of shape memory polymer / 国际生物医学工程杂志

Shape memory polymer (SMP) is a new type of functional materials.SMP has lots of advantages such as low density,light weight,high shape-recovery rate and low cost,but its stiffness is low and shape recovery force is small.Therefore,the reinforced SMP composite has become a hot research focus.The latest progress of reinforced SMP composite is reviewed,with the emphasis placed on the analysis of the influence of reinforced materials on SMP properties including short fibers,particles and the mixture of fibers and particles.Finally,problems exist in the study and the prospect of reinforced SMP composite are discussed briefly.
