Laser-induced graphene (LIG) is one of the most promising graphene-based materials for the
fabrication of flexible electronic devices. However, despite huge efforts to develop LIG on new
substrates there is a lack of stretchable polymers convenient for laser graphenization.
Poly(dimethylsiloxane) is elastomer suitable for flexible electronic fabrication due to excellent
flexibility, optical transparency, hydrophobicity, UV-resistance and good thermal and oxidative
stability. Unfortunately, PDMS cannot be easily graphenized by direct laser writing because of the
low amount of carbon linked to the siloxane chains, mainly consisting of methyl groups. In this
study, a series of PDMS/Triton materials with different concentrations of Triton (1-30 wt.%) was
prepared by casted-based approach starting from divinyl-terminated-PDMS and poly(methylhydrogensiloxane).
Furthermore, direct laser graphenization of PDMS/Triton materials is proposed
for the first time. Different laser parameter...s and multiple writing steps have been examined in order
to induce a graphene-like structure on PDMS/Triton and to increase as much as possible its
conductivity. The prepared PDMS/Triton/graphene composites were characterized by Raman
spectroscopy, scanning electron microscopy (SEM) and sheet resistance measurements. The results
revealed that by adding Triton it is possible to enhance the graphenization degree. The obtained
PDMS/Triton/graphene composites are suitable candidates for flexible microsupercapacitor
fabrication.
