摘　　要：Inspired by the birch bark, which has multilayered structures, we fabricated layer-by-layer （LbL） assembled montmorillonite （MMT） and poly（p-aminostyrene） （PPAS） nanocomposites on cotton fiber curved surfaces to provide protection from atomic oxygen （AO） erosion. The multilayer coated fibers had high flexibility, uniformity, defect free, ease of preparation and low cost. The AO erosion durability has been dramatically enhanced which was evidenced by testing in the ground-based AO effects simulation facility. And the dimension and surface morphologies of the fibers observed by SEM had few changes, indicating excellent AO erosion resistant ability of the coatings. These results provide us a new method to design fibrous materials exposed directly in low earth orbit environment.Inspired by the birch bark, which has multilayered structures, we fabricated layer-by-layer （LbL） assembled montmorillonite （MMT） and poly（p-aminostyrene） （PPAS） nanocomposites on cotton fiber curved surfaces to provide protection from atomic oxygen （AO） erosion.
