“…This results in a change in the geometry of the biocomposite material. In addition, the greater the water absorption in the biocomposite material, the poorer the interface bond strength of the matrix and reinforcement, so the mechanical properties decrease [ 70 , 71 , 72 , 73 , 74 ].…”

Recently, there has been an increase in the number of studies conducted on the process of developing hydroxyapatite (HA) to use in biocomposites. HA can be derived from natural sources such as bovine bone. The HA usage obtained from green mussel shells in biocomposites in this study will be explored. The research goal is to investigate the composition effect of biomaterials derived from polycaprolactone (PCL), polylactic acid (PLA), as well as HA obtained from green mussel shells with a chemical blending method on mechanical properties and degradation rate. First, 80 mL of chloroform solution was utilized to immerse 16 g of the PLA/PCL mixture with the ratios of 85:15 and 60:40 for 30 min. A magnetic stirrer was used to mix the solution for an additional 30 min at a temperature and speed of 50 °C and 300 rpm. Next, the hydroxyapatite (HA) was added in percentages of 5%, 10%, and 15%, as well as 20% of the PLA/PCL mixture’s total weight. It was then stirred for 1 h at 100 rpm at 65 °C to produce a homogeneous mixture of HA and polymer. The biocomposite mixture was then added into a glass mold as per ASTM D790. Following this, biocomposite specimens were tested for their density, biodegradability, and three points of bending in determining the effect of HA and polymer composition on the degradation rate and mechanical properties. According to the findings of this study, increasing the HA and PLA composition yields a rise in the mechanical properties of the biocomposites. However, the biocomposite degradation rate is increasing.

This study focuses on enhancing the mechanical and thermal properties of thermoplastic starch (TPS) and natural rubber (NR) blends through the incorporation of polyethylene glycol (PEG 2,000) and various types of modi ed natural rubber such as epoxidized natural rubber (ENR), poly(methyl methacrylate) grafted natural rubber (NR-g-PMMA), and poly(butyl methacrylate) grafted natural rubber (NR-g-PBMA).The in uence of TPS/NR blend ratios, PEG content, and type of modi ed NR on the properties of the blends was investigated along with their water absorption and bio-degradation. The increase in ductile properties of the TPS/NR blends can be achieved by increasing the NR content. Among the series of TPS/NR blends, the highest toughness (1,630 MJ/m 3 ) can be observed when the blend was formulated from 1.0 wt% of PEG and 10.0 wt% of ENR. The water absorption of TPS/NR blends was found to be lower than the TPS sample, but still exhibited a high water absorption rate compared to the other conventional polymers. The bio-degradation test con rmed the bio-degradation capability of TPS/NR blends according to ASTM 5988-12, and the result revealed that more than 80% of the tested samples can be bio-degraded in soil within 90 days.
