Effects of chemical modification wood with innovative ionic liquid on the supermolecular and morphology wood/polypropylene composites were investigated using X-ray diffraction, hot stage optical microscopy, differential scanning calorimetry. For first time treatment was conducted solely newly synthesized liquid, didecyldimethylammonium bis(trifluoromethylsulfonyl)imide. The found to be responsible for significant changes in nucleating abilities polypropylene matrix. These findings confirmed...
The article presents characteristics of wood/polypropylene composites, where the wood was treated with propolis extract (EEP) and innovative propolis-silane formulations. Special interest in for impregnation is due to its antimicrobial properties. One formulation (EEP-TEOS/VTMOS) consisted EEP, tetraethyl orthosilicate (TEOS), vinyltrimethoxysilane (VTMOS), while other (EEP-TEOS/OTEOS) contained octyltriethoxysilane (OTEOS). fillers were characterized by Fourier transform infrared...
Abstract Chemical modification of lignocellulosic fillers is a hydrophobization process that has been used for years in the production wood-polymer composites (WPCs). However, finding new, more effective modifiers still big challenge and remains subject much research. This study involved chemical wood with use newly designed ammonium imidazolium ionic liquids containing reactive functional groups. The effectiveness was confirmed using FTIR XRD techniques. effect on supermolecular structure...
Polymer composites with renewable lignocellulosic fillers, despite their many advantages, are susceptible to biodegradation, which is a major limitation in terms of external applications. The work uses an innovative hybrid propolis-silane modifier order simultaneously increase the resistance fungal attack, as well ensure good interfacial adhesion filler-polymer matrix. Polypropylene 30% pine wood content were obtained by extrusion and pressing. samples exposed fungi: white-rot fungus...
Abstract The thermal modification of wood can be an interesting way improving adhesion in polymer composites, although the mechanical properties composites with heat treated presented so far many works arouse much controversy. In this work, effects on supermolecular structure and morphology wood/polypropylene (WPC) were investigated using X‐ray diffraction, hot stage optical microscopy, differential scanning calorimetry. A significant impact conditions formation polymorphic varieties matrix...
Abstract The activity of isotactic polypropylene (iPP) nucleating additives during shear flow composite materials is still not entirely explained. In current work the sol‐gel method was employed to synthesize MgO·SiO 2 filler, surface‐modified with trivalent lanthanum. crystallization commercial iPP in presence 0.5% by weight La 3+ modified or unmodified silicates analyzed. wide angle X‐ray scattering analysis proved that even small amount filler influences significantly on supermolecular...
In this work, the surface of pine wood used as a filler in polypropylene/wood composites was successfully modified by mercerization process. It is very significant process because it removes low-molecular components, which improves interactions between and matrix leads to better dispersion matrix. Unfortunately chemical treatment may affect nucleation lignocellulosic filler. On basis XRD results, transformation native cellulose I II observed. present study, effect mercerisation on ability...
