“…The incorporation of fillers into the polymer matrices improves the properties of these polymers and compensates for the drawbacks such as mechanical failure and cracks. The filler interacts with the polymer matrix by facilitating the interlocking mechanism of polymeric chains and thus increases the hardness of the composite (Rajendran et al 2011 ). Also, the type, concentration, and size of filler are important parameters to be considered when synthesizing a polymer composite.…”

“…Also, by increasing bamboo fiber content in the recycled talc-filled polypropylene/ ethylene-propylene-diene monomer (EPDM) (Inacio et al 2017) and due to the addition of talc in recycled polyethylene terephthalate/basalt fiber composite (Kráčalík et al 2008), the flexural strength, tensile strength, and fatigue of composites increased. Due to the addition of graphite, mica, and talc, the impact strength of kenaf wood recycled polyethylene was enhanced as well as the glass transition temperature of recycled plastic composite, WrPC (Ramli et al 2018).…”

The rising use of radioactive elements is increasing radioactive pollution and calling for advanced materials to protect individuals. For instance, polymers are promising due to their mechanical, electrical, thermal, and multifunctional properties. Moreover, composites made of polymers and high atomic number fillers should allow to obtain material with low-weight, good flexibility, and good processability. Here we review the synthesis of polymer materials for radiation protection, with focus on the role of the nanofillers. We discuss the effectivness of polymeric materials for the absorption of fast neutrons. We also present the recycling of polymers into composites.

“…The strain at break changed from 87.42% for PVC to 2.97% for A1, 3.11% for A2, 3.20% for A3, 3.36% for A4, and 3.65% for A5. This may be due to the effect of OPF and PBCC on the polymer chain mobility and the deformability of a rigid interface created between OPF/PBCC and PVC. , …”

“…This may be due to the effect of OPF and PBCC on the polymer chain mobility and the deformability of a rigid interface created between OPF/PBCC and PVC. 13,44 Table 7 indicates that the principal values of notched strength of the Izod impact on composites PVC/OPF/PBCC are significantly reduced by the presence of OPF that diminishes PVC ductility and gives more frictional effects. 45 The impact strength of A2 is greater than those of A1, A3, A4, and A5 due to the finer PBCC dispersion in the PVC matrix.…”

Wooden Polymer Composites of Poly(vinyl chloride), Olive Pits Flour, and Precipitated Bio-Calcium Carbonate

As a filler to be inserted into poly(vinyl chloride) (PVC), low-cost olive pits flour (OPF) and precipitated bio-calcium carbonate (PBCC)-produced PVC/OPF/PBCC composites have been used with high stability and rigidity compared to PVC. Hydrogen bonding is generated between OH cellulose in OPF and H in PVC. Composite tensile modulus increased in PVC grid in the presence of PBCC and OPF, possibly because of a filler restriction effect on the polymer chains. The hardness also increased as both OPF and PBCC increased. The mechanical tendency of the PVC/ OPF composite was improved by adding a low content of PBCC particles with the PVC network, resulting in a smart distribution in the range of 10% by weight, and it was reduced by adding more than that percentage. The successful distribution of PBCC in PVC/OPF composite strengthened the mechanical path. The morphology and possible interface adhesion of components in the composite were demonstrated by scanning electron microscopy (SEM). The PVC SEM images showed a homogeneous, smart, and consistent surface, while the PVC/60 wt % OPF SEM images showed a large number of voids that suggested weak PVC/OPF interactions. The SEM images showed outstanding PBCC distribution in the PVC/OPF matrix for the PVC/50 wt % OPF/10 wt % PBCC composite. Due to the accumulation of PBCC particles producing cavities, the distribution of particles became nonhomogeneous at percentages above 10 wt %. At a low filler material, better spread of PBCC particles in the PVC grid was achieved. Owing to the polarity of OPF, the H 2 O absorption and thickness swelling of PVC/OPF/PBCC composites showed higher amounts than PVC. PBCC improved the thermal stabilization and the neutralization of Cl − negative ions as an acid acceptor of secondary PVC stabilization.

The objective of this research is to investigate the effect of incorporating graphite filler on mechanical, thermal and morphological properties of wood recycled plastic composites (WrPC). WrPC was prepared using recycled polypropylene (rPP), kenaf core, maleic anhydride polypropylene (MAPP) and graphite filler. The graphite content in WrPC is 3 phr. All materials were premixed manually and fed into a single screw extruder and compression molded to prepare mechanical test specimens. The effect of graphite on tensile properties, impact strength, glass transition temperature (Tg) and morphological properties of WrPC were studied. Tensile strength was increased from 6.81 MPa to 10.07 MPa due to stronger interfacial adhesion between graphite and kenaf/rPP. However, the tensile modulus decreased significantly with the incorporation of graphite. Impact strength of WrPC was increased from 2.48 kJ/m2 to 2.83 kJ/m2 due to the present of graphite that gave effective distribution of applied stress and increase resistance of crack propagation. DSC results indicated that Tg of graphite/WrPC is comparable to WPC at 163°C. The internal structure of WrPC showed the addition of graphite had filled the voids and lead to smooth morphology.
