Study on the Response Surface Modelling by Central Composite Design and Optimization of paper Nanocoating

Abstract:

By the superficial grafting of monochlorotriazinyl- b-cyclodextrin (MCT-b-CD) on a special paper (Japanese veil), hosting nanocavities are generated, which can include certain guest chemicals for special protection effects (antibacterial nanocoatings, deodorants, UV protector etc). The original results obtained in the experimental research have been used for the statistic modelling of the grafting process. The regression equations determined through orthogonal Central Composite Design (CCD) represent the objective functions necessary for maximizing optimization. The canonical analysis of the obtained response surfaces was carried out. In order to obtain the optimum grafting conditions, the Lagrange multipliers method was used. Eventually the maximum grafting degree was established, adequate for the stage of subsequently including the guests to attenuate the destructive effects of the environment factors on the heritage documents written on paper support. Keywords: Central Composite Design, Response Surface Methodology, grafting, nanomaterials
