“…Insignificant decreasing of flexural modulus (curve 1) and small diminishing of tensile modulus (curve 2) could be explained by increasing irregular dispersion of nanoclay particles in polypropylene matrix, what extends heterogeneity of the wood plastic hybrid composites. This phenomena partly confirms our SEM investigations (see Figures 6b-6c) and experience of another researchers [15][16][17][18][19][20]. The main challenge for preparation of good quality WPHC is to get even distribution of nanoparticles in polymer matrix melts, but it is not always possible.…”

“…Changes of the Cloisite 15A content in composite (1) Frequently, for products from WPC and WPHC it is important to know their surface hardness. For example, facade and floor boards, products for automotive applications [17] and et al Therefore, investigations on influence of nanoclay additions on chosen polypropylene hybrid composite microhardness (MH) also were done. Obtained results showed that nanoclay noteworthy increase surface MH of the composite samples in the rank: pure PP (MH = 87.12 MPA), PP + 40 wt.% PSWD + 7 wt.% MAPP (170.92 MPa), PP + 40 wt.% PSWD + 7 wt.% MAPP + 3 wt.% Cloisite 15A (187.2 MPa) and maximum PP + 40 wt.% PSWD + 7 wt.% MAPP + 5 wt.% Cloisite 15A (195.54 MPa).…”

“…SEM investigations also confirmed positive action of coupling agent on strengthening of adhesion interaction between components wood and PP matrix. Another way how to make better properties of the WPC is to form hybridcomposites [1,[14][15][16][17][18][19][20][21][22][23][24]. Very popular WPC modifiers are nanoparticle additions like organonanoclays, which increase WPC physical-mechanical properties -microhardness, water resistance and diminish barrier properties and combustibility [1, 2, 14-17, 19, 20].…”

During the last 20-30 years many researchers have paid attention to the studies of properties of the wood polymer composites (WPC). A lot of works are closely related to investigations of exploitation properties of wood fibres or wood flour containing polyolefine composites [1,2]. The most useful from wide selection of polyolefines are polypropylenes, but timber industry waste materials comprising lignocellulose fibres are often used as reinforcement of WPC [3][4][5][6][7][8][9][10][11][12]. Plywood industry is not an exception -part of waste materials (by-products) are used for heat energy, i.e. burned. In this work we have approbated reinforcing of polypropylene (PP) with one of the plywood industry by-products, such as birch plywood sawdust (PSWD), which contains wood fibre fractions with different length [13]. The main fraction (50%) includes fibres with length l = 0.5 − 1 mm. Our previous study [13] has confirmed that PSWD is a promising filler for PP reinforcing. Addition of PSWD up to 40-50 wt.% has increased WPC tensile and flexural modulus, but decreased deformation ability of PP matrix, impact strength, water resistance and fluidity of composite melts. It was shown [13] that modification of the composites with interfacial modifier -coupling agent maleated polypropylene (MAPP content up to 5-7 wt.%) considerably improved all the abovementioned properties. SEM investigations also confirmed positive action of coupling agent on strengthening of adhesion interaction between components wood and PP matrix. Another way how to make better properties of the WPC is to form hybridcomposites [1,[14][15][16][17][18][19][20][21][22][23][24]. Very popular WPC modifiers are nanoparticle additions like organonanoclays, which increase WPC physical-mechanical properties -microhardness, water resistance and diminish barrier properties and combustibility [1, 2, 14-17, 19, 20]. The goal of this study was to investigate organonanoclays influence on plywood production industry by-product birch plywood sawdust (PSWD) containing polypropylene wood hybrid composites (WPHC) physical-mechanical and other exploitation properties.

“…In order to access extraordinary properties, it is essential to develop WPC foams with reduced cell size and narrower cell‐size distribution [7]. Addition of nanoparticles [e.g., nanoclay and carbon nanotubes (CNTs)] may be one of the ways to decrease cell size and achieve more uniform cells in WPCs.…”

Experimental results are presented for nanocomposite foams based on unplasticized poly(vinyl chloride)/(wood flour)/(multi‐wall carbon nanotubes) (PVC/WF/MWCNTs). The nanocomposite samples were prepared in an internal mixer and foamed via a batch processing method using compression molding. Nanoparticles were functionalized by sodium hypochlorite solution, and the functionalization process was monitored by Fourier‐transform infrared spectroscopy. The effects of MWCNTs (both neat and functionalized) and blowing agent concentration on the morphological properties (cell size and cell density) and mechanical properties (tensile and flexural strength) of the foam samples were studied. The results revealed that foam cell sizes decreased and cell densities increased with addition of MWCNTs. The dispersion of nanoparticles in the PVC medium was increased by functionalization, and the morphological properties of the foams containing functionalized nanoparticles were improved. Density of nanocomposite foams decreased more with functionalized MWCNTs as compared to other samples. Chemical blowing agent concentration had no significant effect on sample density. Mechanical properties of the samples were improved by using functionalized MWCNTs in comparison with those of foams without this component. J. VINYL ADDIT.
