Effect of filler content and size on the properties of ethylene vinyl acetate copolymer–wood fiber composites

Abstract

In this study, the main focus was on the effect of wood fiber (WF) content and particle size on the morphology and mechanical, thermal, and water-absorption properties of uncompatibilized and ethylene glycidyl methacrylate copolymer (EGMA) compatibilized ethylene vinyl acetate copolymer-WF composites. For uncompatibilized composites, the tensile strength decreased with increasing WF content, whereas for compatibilized composites, the tensile strength initially decreased, but it increased for composites containing more than 5% WF. Small-WF-particle-containing composites had higher tensile strengths than composites containing larger WF particles, both in the presence and absence of EGMA. WF particle size did not seem to have much influence on the degradation behavior of the composites, whereas water absorption by the composites seemed to be higher in composites with smaller particle sizes for both compatibilized and uncompatibilized composites.

Effect of sol–gel derived nano-silica and organic peroxide on the thermal and mechanical properties of low-density polyethylene/wood flour composites

“…6). This is in line with the work done by Dikobe and Luyt [30], and can be explained by the weak interaction between hydrophilic WF and hydrophobic LDPE. It is, however, interesting to see that the presence of nanosilica further reduces the tensile strength of the LDPE/WF/ nano-silica composites.…”

Effect of ethylene glycidyl methacrylate compatibilizer on the structure and mechanical properties of clay nanocomposites modified with ethylene vinyl acetate copolymer

“…Work done by Dikobe and Luyt, 27 however, showed that EVA and EGMA do not react with each other. EVA and EGMA are, however, very miscible (according to differential scanning calorimetry curves not presented).…”

Preparation and properties of tung oil‐based composites using spent germ as a natural filler

“…As the particle size in a composite decreases, the filler dis- persion and matrix-filler interaction, although it may be weak, should increase. 35 The increased interaction and interfacial adhesion would result in the higher modulus observed. But this trend was not observed when the fine particles were removed from the filler (entries 8 and 9).…”
