    Influence of Surface Treatment of Fillers on Mechanical, Surface, and Water Sorption Behavior of Natural-Fiber Polypropylene Composites
    (Wiley, 2016) Atikler, U.; Tihminlioglu, F.
    The objective of this chapter is to prepare polypropylene (PP)/lignocellulosic fiber composites composed of three different natural fibers, CE, SD, and wheat straw (WS), and to investigate the effects of surface treatment type and amount of coupling agents on the mechanical, morphological, and water uptake properties of PP/fiber composites. Two silane coupling agents, namely (3-aminopropyl)-triethoxysilane (AS) and methacryloxy propyl trimethoxy silane (MS), and maleic anhydride polypropylene copolymers (MAPP) were employed in order to increase the compatibility between the fiber and the matrix. The improvement in the interfacial interaction was also confirmed by using the Pukánszky model. Mechanical test results clearly showed that both silane and MAPP treatments increased the tensile strength and Young's modulus. Mechanical test and water sorption results and scanning electron micrographs (SEMs) of the PP/fiber composites indicated that PP composites containing SD treated with MAPP experienced maximum improvement concerning compatibility and interfacial adhesion between the fiber and the matrix. © 2016 Wiley-VCH Verlag GmbH & Co.

    Sustainable Bio-Nano Composite Coatings for the Protection of Marble Surfaces
    (Elsevier Masson SAS, 2015) Ocak, Y.; Sofuoglu, A.; Tihminlioglu, F.; Böke, H.
    Water repellency on natural stone surfaces is the most important issue in the protection of stone monuments from effects of atmospheric pollutants. In this study, effectiveness of a bio-nano composite coating, composed of a biodegradable polymer (poly-L-lactide [PLA]) and montmorillonite clay (MMT) was investigated for the protection of marble surfaces from pollution. The clay dispersion in polymer matrices was analyzed by using Scanning Tunnel Electron Microscopy (STEM) and X-Ray Diffraction (XRD), while protection performance was investigated by the measurement of surface roughness, wettability, water vapor permeability, capillary water absorption, and color changes on the marble surfaces. As a result, no alteration on the color of coated marbles was observed, significant improvement was obtained for hydrophobicity of the surface and inhibition of sulfation reaction on the exposed marble surfaces under acidic atmosphere. It could be said that PLA based nanocomposites seem to be promising materials as protective coating agents in reducing the effects of water and atmospheric pollutants on marble surfaces. © 2014 Elsevier Masson SAS.
