Bio-based In a new study, two coffee/polydimethylsiloxane (PDMS) composite coatings with 5 and 10 % weight coffee were prepared, and pristine PDMS was selected as the control. In the antialgal test, both coffee/PDMS coatings exhibited excellent antialgal capability, while pristine PDMS was covered with many algal cells. In the antibacterial test, both coffee coatings showed better antifouling capability than the pristine PDMS, and the 10 % coffee coating showed the best antifouling capability.
