: In this present work, we aim to improve the hydrophobicity of a polydimethylsiloxane (PDMS) surface. Various heights of 3D PDMS micropillars were fabricated via grayscale photolithog�raphy, and improved wettability was investigated. Two approaches of PDMS replication were demonstrated, both usin...
