摘要:Novel and intelligent plasma copolymers based on hydrophilic/hydrophobic monomers with tunable wettability and pH-responsiveness are demonstrated. A series of plasma copolymer coatings with various carboxylic acid and fluorocarbon group ratio are prepared on the low-density polyethylene (LDPE) surfaces via capacitively coupled radio frequency plasma (CCP). The static water contact angles (SWCA) of C4F8-co-AA plasma polymer coatings on nanotextured LDPE surfaces tuned from 163 to 4 degrees. These C4F8-co-AA plasma polymer coatings showed different pH-responsiveness by the combined effect of the carboxylic acid to fluorocarbon group ratios and surface nanotexture. The increase of carboxylic acid groups of C4F8-co-AA plasma polymers shifted the reversibly switchable wettability of pH-responsiveness towards low SWCA range. The magnifying effect of surface nanotexture on pH-responsiveness was also observed.
