I am trying to transfer laser-induced graphene to PDMS. I have ablated polyimide sheet using a commercial laser (VLS 3.60 with 30 watt, 10.6 µm CO2 Laser Source) with a speed of 11% and power of 17% as mentioned in (Article Multiresponsive Soft Actuators Based on a Thermoresponsive H...
). However, while I am peeling the PDMS layer, it is getting torn at the portion where LIG starts as shown in the video. Few works reported transferring LIG over PDMS by pouring over LIG and peeling off, but somehow we are failing in transferring. I have tried with a thin layer (by spin coating) as well as with a thick layer of PDMS, but it did not work. Kindly help me with this.

Thank you, J. Rafiee
for your suggestion. I have tried several combinations of LIG. However, I will try some more.

Try to adjust the laser scan speed and power of the laser. probably slow scan and high power of laser which cut high depth (ablate) during processing. After processing, heat the laser-treated film (40-50 oC) and take care when transferring using tweezers.
You can also try using free-standing graphite oxide thin film (transfer-free approach) using its laster treatment (Energy 179 (2019) 676e684)
