The polymer swelling modifications could be erased by simply heating the sample in an oven at 13 160 ºC, while ablated areas could not be erased because of irreversible loss of sulfur species from the polymer in these regions. These capabilities were leveraged in demonstrations of erasable information encoding and direct laser lithography of complex images. The low-cost of the materials and laser systems used in this study and the simplicity of the method compare favorably to other methods of lithography that require complex polymer structures, high-power lasers, and multi-step masking, developing and washing protocols. Furthermore, the direct modification of this class of polymers with low-power lasers is another advance in the growing applications of polymers made by inverse vulcanization.
