Adjustable wettability of paperboard by liquid flame spray nanoparticle deposition

Review on hygroscopic aging of cellulose fibres and their biocomposites

“…Furthermore, the contact angle between a liquid and a solid surface differs with the surface roughness as well as the surface energy or chemistry (Ding et al, 2006). Therefore, many studies and reviews have been reported on coating techniques to increase surface roughness such as sol-gel process, etching, electrospinning, chemical grafting, chemical vapour deposition and liquid flame spray (Berendjchi, Khajavi, & Yazdanshenas, 2011;Gurav et al, 2014;Hu, Zen, Gong, & Deng, 2009;Lee et al, 2013;Mahadik et al, 2013;Stepien et al, 2011Stepien et al, -2013Synytska, Khanum, Ionov, Cherif, & Bellmann, 2011; Teisala et al, 2010) Important progress achieved in this field has also been reported in several review papers (Genzer & Efimenko, 2006;Ma & Hill, 2006;Nakajima, Hashimoto, & Watanabe, 2001;Sanjay, Annaso, Chavan, & Rajiv, 2012;Song & Rojas, 2013).…”

“…The main advantage of this method is the wide spectrum of metal oxide nanoparticles that can be produced by using different types of precursors. For example, Stepien et al (2011Stepien et al ( , 2012 dissolved titanium(IV) isopropoxide (TTIP) precursor or tetraethyl orthosilicate in isopropanol (IPA) to adjust the moisture properties of paperboard with TiO 2 and SiO 2 nanosized coatings produced by LFS process. In their studies, superhydrophobic paperboard surface with high water contact angle was fabricated by TiO 2 coatings.…”

Long-term corrosion protection by a thin nano-composite coating

“…The continuous nature of the LFS process and its operating conditions at normal pressure enables it to be used to coat a broad variation of substrates, also heat sensitive ones [16][17][18]. In the LFS process the liquid form precursor is diluted in water or alcohol and fed together with the combustion gases into a specially designed burner.…”

Liquid Flame Spray—A Hydrogen-Oxygen Flame Based Method for Nanoparticle Synthesis and Functional Nanocoatings

“…Recently, a slightly less conventional application of the LFS method as a functional coating process has been introduced, where TiO 2 or SiO 2 nanoparticles are deposited onto heat sensitive materials, such as paper or paperboard, in a roll-to-roll scheme, in order to control the wetting of the surface (Teisala et al, 2010;Mäkelä et al, 2011;Stepien et al, 2011;Teisala et al, 2014a;Haapanen et al, 2015). Here, a layer of nanoparticles, with structure and morphology described in Fig.…”
