AB  - One type of electroactive shape memory nanocomposite was fabricated, including 
      cross-linked poly(epsilon-caprolactone) (cPCL) and conductive multiwalled carbon 
      nanotubes (MWNTs). The cross-linking reaction of the pristine 
      poly(epsilon-caprolactone) (PCL) was realized by using benzoyl peroxide (BPO) as an 
      initiator. The raw MWNTs (Raw-M) were prefunctionalized by acid-oxidation process 
      and covalent grafting with poly (ethylene glycol) (PEG), respectively. Three 
      kinds of nanocomposites containing cPCL/Raw-M, cPCL/acid-oxidation MWNTs (AO-M) 
      and cPCL/PEG grafted MWNTs (PEG-M) were obtained, and the mechanical, electrical 
      and shape memory properties were further investigated. The influence of in vitro 
      degradation on their shape memory and mechanical properties was also evaluated. 
      The methyl thiazolyl tetrazolium (MTT) assay was performed to estimate their 
      biocompatibility. The results displayed that these nanocomposites could perform 
      favorable shape memory recovery both in hot water at 55  degrees C and in electric field 
      with 50 V applied voltage. In addition, compared with cPCL/Raw-M and cPCL/AO-M, 
      cPCL/PEG-M composite possessed more favorable properties such as mechanical, 
      biocompatible, and electroactive shape memory functions. Therefore, the 
      nanocomposite may be potential for application as smart bioactuators in 
      biomedical field.
