摘要：

XPS, ATR-FTIR, F-19 MAS solid-state NMR, and imaging TOF-SIMS have been used to compare the depth and extent of chemical modification achieved during nonisothermal CF4 plasma fluorination of nonporous, mesoporous, and microporous polystyrene spheres. It is shown that different depths of functionalization can be achieved by varying the polymer pore architecture. This methodology offers scope for preparing functionalized polymer supports and also protecting moisture-sensitive catalysts for handling in air.
