Article Synopsis
- Biomimetic materials benefit from adding specific chemical features to their surfaces, but preserving their roughness while doing so is a challenge.
- Researchers developed a method using a water-based layer-by-layer approach to modify these materials effectively while maintaining surface texture.
- The resulting PDMS-replica with fluorinated groups displayed superhydrophobic and oil-repellent properties, making it suitable for various applications in different environments.
Surface chemical modification of poly(dimethylsiloxane)-based biomimetic materials: oil-repellent surfaces.
ACS Appl Mater Interfaces
November 2009
The oil-repellent performance of a poly(dimethylsiloxane)-based biomimetic replica (PDMS-replica) was tuned by modifying its surface chemical composition. PDMS-replica possessing a complementary combination of hierarchical roughness and mixed -CF(3) and -SiCH(3) terminal functionality was prepared in the presence of a surface-modifying agent, using nanocasting based on soft lithography. PDMS-replica showed superhydrophobicity and enhanced oil repellency, theta(oil) approximately 86 degrees .

The stability of this attachment chemistry was demonstrated by the retention of the primary oligo through the process of hybridization with a labeled complementary DNA sequence. In these studies, the hybridized labeled DNA oligomers were detected using confocal fluorescence microscopy.
