“…IR spectra of cellulose, hemicellulose and lignin of natural fibres [60] FTIR has been commonly used to characterize natural fibres with various treatments, e.g. grafting [67][68], coupling [69][70][71], mercerization [72][73][74]. With the aid of FTIR, researchers are able to obtain much more in-depth information of natural fibres after various modifications.…”

“…Surface modification, which can be achieved by etching [24], chemical treatment [25,26], or physical treatment [27,28], provides the opportunities to tune optical, electrical, [29][30][31][32][33][34][35] and interfacial [36-38] material properties. Owing to the availability of reactive groups, mostly soft nucleophiles or electrophiles, most polymer surfaces can be readily modified through chemical grafting by simply exposing the material to an appropriate reagent(s) [1,[7][8][9]14,15,[17][18][19][20][21][22][39][40][41][42][43][44][45][46][47][48][49][50][51][52].…”

Abstract:Modifying the chemistry of a surface has been widely used to influence interfacial properties of a material or nature of interaction between two materials. This article provides an overview on the role of polyfunctional molecules, specifically silanes, in surface modification of polar surfaces (bearing soft nucleophiles). An emphasis on the mechanism of the reaction in the presence of adsorbed water, where the modifying reagents are hydrolysable, is discussed. To highlight the complexity of the reaction, modification of paper with trichlorosilanes is highlighted. Preparation of hydrophobic cellulosic paper, and structure-property relations under different treatment conditions is used to highlight that a monolayer is not always formed during the surface modification. Gel-formation via step-growth polymerization suggests that at the right monomer:adsorbed water ratio, a monolayer will not form but rather self-assembly driven particle formation will occur leading to a textured surface. The review highlights recent work indicating that the focus on monolayer formation, is at the very least, not always the case but gel formation, with concomitant self-assembly, might be the culprit in understanding challenges associated with the use of polyfunctional molecules in surface modification.

“…Simultaneously, with polycondensation reactions between the silanol groups, hydrogen bonds between the cellulosic bre hydroxyl groups and the silanol groups are converted into covalent bonds via a condensation reaction. is phenomenon ensures a strong adhesion between the hybrid network and the bre surface, which improves the mechanical properties of the hybrid [28,29]. Contrary to the ϵSi−O−Siϵ bonds, which are stable towards hydrolysis, the ϵSi−O−Cϵ bonds are prone to hydrolysis in high moisture environments.…”
