AB  - Fibrous shape memory polymers (SMPs) have received growing interest in various 
      applications, especially in biomedical applications, which offer new structures 
      at the microscopic level and the potential of enhanced shape deformation of SMPs. 
      In this paper, we report on the development and investigation of the properties 
      of acrylate-based shape memory polymer fibers, fabricated by electrospinning 
      technology with the addition of polystyrene (PS). Fibers with different diameters 
      are manufactured using four different PS solution concentrations (25, 30, 35, and 
      40 wt%) and three flow rates (1.0, 2.5, and 5.0 muL min(-1)) with a 25 kV applied 
      voltage and 17 cm electrospinning distance. Scanning electron microscope (SEM) 
      images reveal that the average fiber diameter varies with polymer concentration 
      and flow rates, ranging from 0.655 +/- 0.376 to 4.975 +/- 1.634 mum. Dynamic 
      mechanical analysis (DMA) and stress-strain testing present that the glass 
      transition temperature and tensile values are affected by fiber diameter 
      distribution. The cyclic bending test directly proves that the electrospun SMP 
      fiber webs are able to fully recover; additionally, the recovery speed is also 
      affected by fiber diameter. With the combination of the SMP material and 
      electrospinning technology, this work paves the way in designing and optimizing 
      future SMP fibers properties by adjusting the fiber diameter.
