“…Albano et al [17] explored the potential of seaweed residue as fillers in high-density polyethylene (HDPE) matrix. The finding showed that the incorporation of seaweed into the polymer matrix resulted in high porosity and poor mechanical properties of the composites.…”

The aim of this paper is to investigate the physical properties of thermoplastic sugar palm starch/agar (TPSA) blend when incorporated with seaweed. The ratio of starch, agar, and glycerol for TPSA was maintained at 70:30:30. Seaweed with various contents (10,20,30, and 40 wt.%) were mixed with TPSA matrix via melt mixing before compression were molded into 3 mm plate at 140 o C for 10 minutes. The prepared laminates were characterized for moisture absorption, water absorption, thickness swelling, water solubility, and density. The results showed that increasing seaweed loading from 0 to 40 wt% has led to a drop in moisture content from 6.50 to 4.96% and 9% reduction of the density. TPSA matrix showed 52.5% water uptake and 32.3% swelling whereas TPSA/seaweed composites (40 wt% loading) showed 97% water uptake and 74.8% swelling respectively. Higher water solubility was also shown by TPSA/seaweed composites (57 wt%) compared to that of the TPSA matrix (26 wt%). After 16 days of storage, the equilibrium moisture content for TPSA and TPSA/seaweed (40 wt% loading) were 23.2 and 25.2% respectively. In conclusion, TPSA/seaweed composites show good environmental friendly characteristics as a renewable material. In future, the properties of this material can be further improved by hybridization with more hydrophobic fillers for better resistance against water.

“…Furthermore, the mechanical, dynamic mechanical, and thermomechanical properties of seaweed‐reinforced biocomposites have also been found to improve upon increasing the fiber loadings at 20 wt% , 30 wt% , and 50 wt% , respectively. Albano et al have focused on studying the properties of seaweed residues filled with high density polyethylene (HDPE) composites. The work has subsequently proved the biocompatibility of seaweed residue incorporated in polymer composite with animal tissue, with no adverse effect observed.…”

Composites consisting of natural rubber (NR) latex as their matrix and low industrial grade seaweed (LIGS) and its extractive (semirefined carrageenan, SRC-LIGS) as the filler were prepared via normal prevulcanization process. An analysis regarding the particle size and morphology of seaweed (LIGS and SRC-LIGS), as well as surface properties and mechanical properties (tensile and tear properties) of NR latex composites, was consequently generated. Furthermore, post-processing treatment for NR latex composites have also been studied, specifically involving leaching, heat aging, water absorption, and soil burial. The particle size of LIGS and SRC-LIGS obtained was recorded to be lower than 100 μm. Thus, the results are indicative of SRC-LIGS's role in improving the thermal properties of NR latex composites. After 8 weeks of soil burial, the incorporation of LIGS and SRC-LIGS into the NR latex composites has accelerated biodegradation processes, thus highlighting their advantage as biodegradable fillers. These properties have consequently contributed to SRC-LIGS/NR latex composites as a potential composite for use in biodegradable applications, such as polybag for pottery and plants. J. VINYL ADDIT.

“…Different techniques have been used to prepare polyolefin/natural fiber composites. These techniques include solution mixing, roll milling, melt mixing, as well as injection and compression molding 1–12. The methods differ in terms of their operating principles and processing parameters, which may lead to fairly different properties of the prepared composite materials.…”

The effect of maleic anhydride-grafted hard paraffin wax (MA-g-wax) and oxidized hard paraffin wax (OxWax), as possible compatibilizers, on the morphology, thermal and mechanical properties of LDPE/sisal fiber composites were examined. The differential scanning calorimetry (DSC) results show that sisal alone did not change the crystallization behavior of LDPE, while the two waxes influenced the crystallization behavior of LDPE in different ways, whether mixed with LDPE alone or in the presence of sisal. The thermal properties seem to be influenced by the fact that the waxes preferably crystallize around the short sisal fibers, and by the fact that the two waxes have different compatibilities with LDPE. The TGA results show an increase in the thermal stability of the blends in the presence of the two waxes, with LDPE/ OxWax showing a more significant improvement. The presence of wax, however, reduced the thermal stability of the LDPE/sisal/wax composites. The presence of OxWax and MA-g-wax similarly influenced the tensile properties of the composites. Both waxes similarly improved the modulus of the compatibilized composites, but in both cases the tensile strengths were worse, probably because of a fairly weak interaction between LDPE and the respective waxes.
