AB  - Laser irradiation of polymeric materials has drawn great attention as a fast, 
      simple, and cost-effective method for the formation of porous graphene films that 
      can be subsequently fabricated into low-cost and flexible electronic and 
      energy-storage devices. In this work, we report a systematic study of the 
      formation of laser-induced graphene (LIG) with sheet resistances as low as 9.4 
      Omega/sq on parylene-C ultrathin membranes under a CO(2) infrared laser. Raman 
      analysis proved the formation of the multilayered graphenic material, with 
      I(D)/I(G) and I(2D)/I(G) peak ratios of 0.42 and 0.65, respectively. As a proof 
      of concept, parylene-C LIG was used as the electrode material for the fabrication 
      of ultrathin, solid-state microsupercapacitors (MSCs) via a one-step, scalable, 
      and cost-effective approach, aiming at future flexible and wearable applications. 
      The produced LIG-MSC on parylene-C exhibited good electrochemical behavior, with 
      a specific capacitance of 1.66 mF/cm(2) and an excellent cycling stability of 96% 
      after 10 000 cycles (0.5 mA/cm(2)). This work allows one to further extend the 
      knowledge in LIG processes, widening the group of precursor materials as well as 
      promoting future applications. Furthermore, it reinforces the potential of 
      parylene-C as a key material for next-generation biocompatible and flexible 
      electronic devices.
