将两亲性含氟聚合物聚(N-1H，1H-pentadecafluorooctylmethacrylamide)(pC7F15MAA))溶解在两种可混溶的溶剂(AK-225和冰醋酸)中，制备了含氟聚合物纳米微粒薄膜。通过将该溶液滴涂在基片上，得到了超疏水的多孔膜。随着AK-225与醋酸的比例增大，pC7F15MAA在醋酸液滴周围致密，形成了pC7F15MAA纳米粒子。通过改变混合比或总浓度，考察了纳米颗粒膜的制备条件。利用超疏水多孔pC7F15MAA纳米颗粒膜的智能表面，成功地制备了一种高灵敏度的溶解氧传感器系统。在溶氧浓度为0~40 mg L-1范围内，灵敏度为I0/I40=12 6。并与文献报道的氧敏性进行了比较。
Fluorinated polymer nanoparticle films were prepared by dissolving amphiphilic fluorinated polymer, poly (N-1H, 1H-pentadecafluorooctylmethacrylamide)(pC7F15MAA) in two miscible solvents (AK-225 and acetic acid). A superhydrophobic and porous film was obtained by dropcasting the solution on substrates. With higher ratios of AK-225 to acetic acid, pC7F15MAA was densified around acetic acid droplets, leading to the formation of pC7F15MAA nanoparticles. The condition of the nanoparticle film preparation was investigated by varying the mixing ratio or total concentration. A highly sensitive dissolved oxygen sensor system was successfully prepared utilizing a smart surface of superhydrophobic and porous pC7F15MAA nanoparticle film. The sensitivity showed I 0/I 40= 126 in the range of dissolved oxygen concentration of 0~ 40 mg L-1. The oxygen sensitivity was compared with that of previous reports.
