Superhydrophobic bio-fibre surfaces via tailored grafting architecture

Abstract

Superhydrophobic bio-fibre surfaces with a micro-nano-binary surface structure have been achieved via the surface-confined grafting of glycidyl methacrylate, using a branched "graft-on-graft" architecture, followed by post-functionalisation to obtain fluorinated brushes.

Preparation of stable polymeric grafted layers on poly(ethylene terephthalate) by thermal annealing

“…The modification of polymeric substrates by grafting is an important route to modify a polymer surface properties and to introduce new functions, for example, biocompatibility 1 , adhesion 2 , friction 3 , lubrication 4 , hydrophobicity 5 , or hydrophilicity 6 , to the substrates. There are two main approaches to graft polymers onto solid surfaces: grafting-from and graftingto 7,8 .…”

Superhydrophobic cotton fabrics prepared by sol–gel coating of TiO2and surface hydrophobization

“…Among others, superhydrophobic textiles have been successfully obtained by a number of different approaches [9][10][11][12][13][14][15][16]. For example, Gao and McCarthy, according to a 1945 patent, grafted a silicone coating to a microfiber polyester fabric to render the fabric superhydrophobic [9], but the microfiber polyester fabric (with a single fiber as small as 2-5 µm) must be tightly woven, and this approach may not be suited to cotton textiles.…”

Preparation of superhydrophobic surfaces on cotton textiles

“…With the deepening of the research on superhydrophobic surfaces, textile substrates have been gradually paid attention again owing to the abundance and inexpensiveness of raw materials and easy large-scale area production. To date, a number of different approaches have been adopted to prepare superhydrophobic textiles [13][14][15][16][17][18][19][20][21]. Gao and McCarthy [13] grafted a silicone coating to a microfiber polyester fabric to render the fabric superhydrophobic according to a 1945 patent.…”
