The aim of this work was to evaluate the potential of cold plasma polymerization as a simple, fast and versatile technique for deposition of protective hydrophobic and oleophobic polymer layers on hydrophilic biopolymer aerogels. Polymerization of different fluorinated monomers (octafluorocyclobutane C4F8 and perfluoro-acrylates PFAC-6 and PFAC-8) on aerogel monoliths derived from alginate, cellulose, whey protein isolate (WPI) and potato protein isolate (PPI) resulted in fast and significant surface hydrophobization after short process times of 5 min and led to superhydrophobic surfaces with static water contact angles up to 154° after application of poly-C4F8 coatings. Simultaneous introduction of hydro- and oleophobicity was possible by deposition of perfluoro-acrylates. While the porous structure of aerogels stayed intact during the process, polymerization inside the aerogels pores led to the generation of new porous moieties and resulted therefore in significant increase in the specific surface area. The magnitude of the effect depended on the individual process settings and on the overall porosity of the substrates. A maximization of specific surface area increase (+179 m2/g) was obtained by applying a pulsed wave mode in the C4F8-coating of alginate aerogels.

This article will consider how dress, textiles, manuscripts and images in the Thomas Hardy Archive illuminate his writing and reveal the accuracy of his descriptions of clothing in novels including Far from the Madding Crowd and Tess of the D'Urbervilles. Rural clothing, fashionable styles, drawings and illustrations will shed new light on his writing through providing an insight into the people's dress he described so eloquently in his writing. The textiles and clothing in the Archive are also significant as nineteenth-century working-class dress is relatively rare. Everyday rural clothing does not tend to survive, so a collection belonging to Hardy's family of country stonemasons provides new opportunities for research in this area. Even more unusual is clothing reliably provenanced to famous people or writers, and such garments that do exist tend to be from the middle or upper classes. This article will show how the combination of surviving dress, biographical context and literary framework enriches understanding of Hardy's words and informs research into nineteenth-century rural dress.
