摘要：以聚二甲基硅氧烷（PDMS）和纳米 SiO 2 掺杂聚芴醚酮（PFEK），采用溶液喷涂法在纸张表面构筑了耐
用的超疏水涂层。考察了 PDMS 和 SiO 2 用量（以 PFEK 和 N-甲基吡咯烷酮的质量为基准，下同）对纸张水接
触角的影响。结果表明，当 PDMS 和 SiO 2 用量均为 2%时，纸张表面的水接触角达到最大值 170，滚动角最小
值为 1，聚合物将 SiO 2 固定在纸张纤维上，使其表面呈现微纳米粗糙结构。超疏水性源于这种疏水粗糙表面下
积蓄的空气对液滴浸润的抑制。制得的 PFEK/PDMS/SiO 2 喷涂纸经过 40 个摩擦周期或 12 次对折测试后，其水
接触角仍达到 150°以上，能够维持超疏水性能，并具有较好的机械稳定性。拉伸测试表明，涂层将普通纸张的
拉伸强度从 10.1 MPa 增强到 37.8 MPa，在水中浸泡 15 min 后，该喷涂纸的拉伸强度为 25 MPa，仍具有较好的
力学性能。另外，PFEK/PDMS/SiO 2 喷涂纸能够抵抗黏稠泥土的污染，表现良好的自清洁性能。

Abstract: Durable superhydrophobic coating was fabricated on paper substrate by solution-spraying
method using polydimethylsiloxane (PDMS) and silicon dioxide nanospheres (SiO 2) doped poly(fluoreneyl
ether ketone) (PFEK). The effects of PDMS dosage and SiO 2 dosage on the water contact angle of paper
were investigated. The results showed that when both PDMS and SiO 2 dosage were 2% (based on the mass
of PFEK and N-methylpyrrolidone, the same below), the water contact angle of the coating was 170° and
the sliding angle was 1°. The polymer anchored SiO 2 on the surface of paper fiber, resulting in micro-nano
rough structure on the surface. The superhydrophobicity was caused by the inhibition of droplet infiltration by
the air accumulated under the hydrophobic rough surface. The prepared PFEK/PDMS/SiO 2 coated paper
exhibited excellent superhydrophobicity and mechanical stability with water contact angles of above 150°
after 40 cycles of wearing tests and after 12 times of folding tests. Stretch tests revealed that the
PFEK/PDMS/SiO 2 coating enhanced the tensile strength of ordinary paper from 10.1 MPa to 37.8 MPa.
Moreover, after soaking in water for 15 min, the tensile strength of PFEK/PDMS/SiO 2 coated paper was
25 MPa and still had better mechanical properties. In addition, the PFEK/PDMS/SiO 2 could resist
contamination from sticky mud, indicating that it had good self-cleaning performance.
