“…Using FFMWF filler instead of LFMWF resulted in a poor MWF‐polymer interface, leading to more microgaps in the MWPNC structure. There is a significant correlation between the water uptake of the WPC samples and the increase in structural microgaps 56,57 . On the other hand, increasing the number and size of structural microgaps seems to reduce the swelling effect of the filler particles on the thickness swelling of the WPC.…”

“…With increasing immersion time, the index value TS/WU gradually decreases to values below one, indicating a decrease in the thickness swelling of the samples while water uptake remains constant (Figure 5e). The filler content and the structural microgaps seem to influence the water uptake and the thickness swelling of the WPC specimens 2,56,57 . The maximum swelling of the filler particles occurs when the water absorption reaches the fiber saturation point (FSP ≈ 25%–30% MC) 1,58 .…”

“…FFMWF-filled specimens generally showed higher water uptake and lower thickness swelling than comparable LFMWF-filled specimens after 1000 h of immersion in water. Typically, a WPC specimen with higher water uptake is also expected to have more significant thickness swelling 19,56 ; however, the recent results show an apparent contradiction. A detailed discussion of the possible reasons for this contradiction follows.…”

After water uptake, a part of the thickness swelling of the filler particles is spent to fill the microgap and structural discontinuity at the filler-matrix interface before affecting the thickness of the MWPNC sample.…”

This study investigates the effect of removing magnetic nanoparticles from the outer surface of magnetic wood flour (MWF) particles as a filler phase on the microstructural, physical, and mechanical properties of the prepared MWFpolypropylene nanocomposites. For producing MWF with a surface free of magnetic nanoparticles (called LFMWF), in contrast to the commonly produced MWF (called FFMWF), magnetic wood chips were first prepared and then milled. No significant changes were observed in the tensile and flexural strength of the composite specimens prepared with the LFMWF filler instead

The paper presents the results of testing the properties of wood–polymer composites (WPC) based on plasticised poly(vinyl chloride) (PVC-P). Materials with variable contents of wood filler (Arbocel C 320) or plasticiser (di-isononyl phthalate) were produced and then analysed. The share of wood flour in the material was up to 50 phr, and the plasticiser content was up to 40 phr. Functional properties, such as tensile properties, mechanical properties at variable temperature (DMTA), and water absorption, as well as processing properties such as rheological properties and analysis of the fusion process, were analysed. The influences of wood flour and plasticiser on the composites’ properties in the solid and melted state were found. For example, with 40 phr of plasticiser, increasing the filler share from 0 phr to 50 phr resulted in an increased tensile modulus from 18 MPa to 274 MPa and viscosity at a share rate of 20 s−1, from 721 Pa·s to 1581 Pa·s. However, increasing the share of plasticiser from 20 phr to 40 phr with 30 phr of filler reduces the value of these properties from 1760 MPa to 112 MPa and from 2768 Pa·s to 1151 Pa·s, respectively. It was also found that increasing the share of wood flour in the composite noticeably reduces the effectiveness of the plasticiser.
