Abstract

Anthracene-based polymer spin-coated on polydimethylsiloxane (PDMS) substrate was exposed to UV light. A contact angle experiment was conducted to show changes on the surface morphology and verify the photo-writable capabilities of the material. Contact angle results show that the surface hydrophobicity has decreased, which suggest that UV exposure has triggered changes in surface topography. We find the best-fit line for contact angle (θ) vs irradiation time (T) is θ = 10.10e^0.014T + 91.27 where T is in minutes. The polyanthracene-coated PDMS surface was demonstrated to have
potential for use in photolithography.
