“…Initially, the BP was dried in the oven at 105 °C for 24 h to remove the moisture content. Subsequently, PCL and BP were weighed according to the weight percentage, as summarised in Table 1 [ 10 ]. The PCL was then dissolved in the DCM through mechanical stirring at a temperature of 50 °C and a speed of 500 rpm for 1 h, and the BP was slowly added to the solution, stirred for another 30 min to achieve a mixing consistency, and finally, the mixture was poured into a petri dish and oven dried at 40 °C for 24 h. The composite film was then peeled off from the petri dish and broken into small fragments and compressed using a hydraulic hot press at a temperature of 60 °C and a pressure of 20 kPa for 15 min.…”

“…Polycaprolactone (PCL) is a notable biodegradable polymer that can be obtained through the polymerisation of hydroxy caproic acid or by opening the ϵ-caprolactone ring [ 9 ]. PCL has good mechanical properties, such as flexibility and impact resistance [ 10 ], low glass transition and melting temperatures [ 11 ], and biocompatibility. Furthermore, PCL can degrade easily in a short period (a few months to many years), depending on its molecular weight, degree of crystallinity, shape, porosity, and the surrounding environment [ 12 ].…”

The use of biodegradable polymers in daily life is increasing to reduce environmental hazards. In line with this, the present study aimed to develop a fully biodegradable polymer composite that was environmentally friendly and exhibited promising mechanical and thermal properties. Bamboo powder (BP)-reinforced polycaprolactone (PCL) composites were prepared using the solvent casting method. The influence of BP content on the morphology, wettability, and mechanical and thermal properties of the neat matrix was evaluated. In addition, the degradation properties of the composites were analysed through soil burial and acidic degradation tests. It was revealed that BP contents had an evident influence on the properties of the composites. The increase in the BP content has significantly improved the tensile strength of the PCL matrix. A similar trend is observed for thermal stability. Scanning electron micrographs demonstrated uniform dispersion of the BP in the PCL matrix. The degradation tests revealed that the biocomposites with 40 wt·% of BP degraded by more than 20% within 4 weeks in the acidic degradation test and more than 5% in the soil burial degradation test. It was noticed that there was a considerable difference in the degradation between the PCL matrix and the biocomposites of PCL and BP. These results suggest that biodegradable composites could be a promising alternative material to the existing synthetic polymer composites.

The depletion of natural resources due to the aggressive industrialization in the last decades has brought considerable attention to research aimed at developing green and sustainable products using eco-friendly materials. The purpose of the current study was to develop wood polymer composites (WPCs) using recycled plastic waste (RPW) generated from university laboratories and recycled wood waste (RWW) from construction and demolition (C&D) activities by melt-blending technique. The WPCs were characterised for their mechanical and thermal properties, as well as water uptake and morphology. The SEM micrograph indicated good interaction between RWW and RPW matrix. The mechanical strength of the WPCs was found to increase from 26.59 to 34.30 MPa, with an increase of the RWW content in the matrix. The thermal stability was higher in the composite with a higher percentage of RWW in the matrix. The wettability results indicated that the composite with a higher RWW (20%) had a higher water uptake. These results suggest that the produced WPCs can be a promising environmental-friendly material, while maintaining good mechanical, thermal, and wettability properties.

Effects of gamma radiation on nanocomposite films of polycaprolactone with modified MCM-48

et al. 2021

The aim of this investigation was to assess the effects of gamma radiation on nanocomposite films (NC films) formed by PCL (polycaprolactone) with MCM-48 nanoparticles (PCL/MCM-48) and PCL with MCM-48 NPs modified with (3-aminopropyl)triethoxysilane (APTES) (PCL/MCM-48-NH 2 ). The nanocomposite films were obtained using the solvent casting method. After preparing the films, they were irradiated at 25 kGy in the presence of air and analyzed by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FT-IR), differential scanning calorimetry (DSC), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM), transmission electronic microscopy (TEM), as well as for their mechanical properties. The exposure of NC films to gamma radiation at 25 kGy did not cause major changes in either thermal or mechanical properties such as tensile strength and modulus of elasticity. The results revealed that gamma radiation was a successful choice for the sterilization of these materials.
