Many test liquids cleanly glide down crosslinked coatings bearing nanopools of a grafted liquid ingredient for dewetting enablement (NP-GLIDE coatings) at low substrate tilt angles. It was unclear if an engineering plastic with a high glass transition temperature Tg could replace a crosslinked coating matrix to support an NP-GLIDE coating. This paper reports the uniform grafting via click chemistry of liquid poly(dimethyl siloxane) (PDMS) onto poly(arylene ether sulfone) (PAES, T_g = 185 °C) to yield graft copolymers PAES-g-PDMS with low polydispersity indices. Hexadecane droplets (5 μL) cleanly glided down at sliding angles (SAs) of less than 3 ± 1° on all of the coatings prepared from PAES-g-PDMS with PDMS weight fractions of 3.4%, 19%, 30%, and 40%, respectively. Further, an oil-based ink readily contracted on them. The sliding angle of 15 μL droplets decreased from 47 ± 2° to 13 ± 1° as the PDMS weight fraction increased from 3.4% to 30%.

许多测试液体可以在低基材倾斜角下顺滑地滑落带有接枝液体成分纳米池的交联涂层（NP-GLIDE涂层），以实现去湿性。目前尚不清楚玻璃化转变温度高Tg的工程塑料是否可以代替交联涂层基质来支撑NP-GLIDE涂层。本文报道了通过点击化学将液态聚二甲基硅氧烷（PDMS）均匀接枝到聚亚芳基醚砜（PAES，T _g  = 185°C）上以得到低多分散指数的接枝共聚物PAES- g -PDMS。在由PAES- g制备的所有涂层上，十六烷液滴（5μL）干净滑行，滑动角（SAs）小于3±1°-PDMS的PDMS重量分数分别为3.4％，19％，30％和40％。此外，油基油墨容易在其上收缩。随着PDMS重量分数从3.4％增加到30％，15μL小滴的滑动角从47±2°减小到13±1°。
