Summary: This study aimed to prepare nonwovens from polylactic acid and polybutylene succinate using the melt-blown process. The research found that increasing air pressure and die-to-collector distance resulted in smaller fibers. Tensile strength and elongation at the break were dependent on the polymer and process parameters. Polybutylene succinate could only be processed into nonwovens at larger die-to-collector distances.

Summary: The COVID-19 pandemic has generated a massive demand for disposable facemasks, resulting in plastic pollution due to the use of nonbiodegradable materials. To address this issue, the study focuses on manufacturing biobased and biodegradable facemasks using melt electrospinning technique. The effects of various parameters on fiber diameter and uniformity are investigated, along with the impact of climate chamber and infrared heater on fiber solidification. The study provides insights into process optimization and highlights the unsuitability of the produced samples as filter materials for medical face masks due to their large pore size.

Summary: Polybutylene succinate/modified cellulose bio-nanocomposites were synthesized and used as sorbents for needle trap microextraction of polycyclic aromatic hydrocarbons. The modified cellulose nanocrystals improved the dispersion of nanoparticles in the matrix and enhanced the surface area and stabilities. The extraction parameters were optimized, resulting in a method with low detection limits, good repeatability and reproducibility, and a wide linear range. The developed method showed high enrichment factors and relative recovery values in real water samples.

Summary: This article qualitatively reviews the impact of various parameters in the melt blending processing on the mechanical properties of polymer nanocomposites. It is found that the tensile modulus of the extruded nano-sized fillers-reinforced polymers is highly influenced by the distribution and orientation of the fillers. The use of intermeshing co-rotating twin-screw extruders can produce nanocomposites with superior mechanical strength.

Summary: This study investigated the influence of polybutylene succinate (PBS) content on the physical, thermal, mechanical, and chemical properties of polylactic acid (PLA)/PBS composite fibers. The addition of PBS affected the fiber size distribution and surface smoothness. The results of DSC and X-ray diffraction analysis showed that PBS addition decreased the crystallization temperature and increased the crystallinity of PLA. Furthermore, adding PBS increased the tensile properties but significantly decreased the elongation at break.

Summary: Developing water-saving technologies like Groasis Waterboxx (GW) using environmentally friendly materials has emerged as a robust strategy to reduce the negative impact of agriculture on the environment and society. In this study, injection molding of green GWs made of poly-lactic acid (PLA) and polybutylene succinate (PBS) was simulated, and the performance of the parts in harsh conditions was analyzed. The simulation results showed that PLA had faster production speed compared to polypropylene (PP), while PBS demonstrated mechanical qualities similar to PP and provided a high safety factor. Despite consuming more energy for injection, substituting PP with PBS is justified considering its efficiency and eco-friendliness.

Summary: Polybutylene terephthalate (PBT) hybrid nanocomposites reinforced with synthetic wollastonite nano-fibers (SWN) and graphene oxide (GO) were prepared by melt compounding. The study investigated the effect of GO content on the properties of PBT/SWN/GO nanocomposites. The hybridization of SWN and GO improved the mechanical, thermal, and tribological properties, but the poor interaction between GO and PBT matrix limited the reinforcing effect of SWN.

Summary: The purpose of this study is to investigate the impact of graphene oxide-silica nanocomposites on the mechanical properties, transport properties and microstructure of mortar, and to understand the mechanism by which GO-nanoSiO2 improves the properties of mortar. The results showed that adding 0.05 wt% GO effectively enhanced the compressive strength, fracture toughness and chloride penetration resistance of mortar. The addition of GO-nanoSiO2 also resulted in improved pore structure and reduced porosity, leading to improved impermeability. In the interface transition zone between aggregate and matrix, the presence of GO-nanoSiO2 inhibited crack propagation and improved the macroscopic fracture properties of mortar.

Summary: We investigate the gas transport behavior of polymer-grafted nanoparticle (GNP) membranes and discover interesting and universal phenomena. Through theoretical analysis and experimental measurements, we propose a mechanism for the peak gas permeability based on the extension free energy of the polymer chains. Our findings suggest that the curved polymer brushes behave like a two-layer transport medium, with extended chains near the NP surface speeding up gas transport.

Summary: Phosphonium based ionic liquids (ILs) have been shown as a new class of epoxy prepolymer initiators, which significantly affect the dielectric behavior of epoxy-IL systems. Excessive IL content acts as a plasticizer, decreasing Tg and inducing heterogeneities in the network. A high IL content leads to an omega relaxation mode and an increase in chain mobility observed through dielectric spectroscopy.

Summary: Electrothermal processes were investigated in pyroresistive composites of high-density polyethylene with carbon black and carbon fibers. The kinetic heating curves showed an exponential dependence with a heating rate constant for each composite. Equilibrium temperature was reached after a short heating time, and decreased with the presence of positive temperature coefficient of resistance (PTC) effect. The composites exhibited self-regulating capability and the equilibrium temperature depended on the applied voltage and electric power with different relationships. An application of using HDPE-CB composite as a heating element for resistance welding was demonstrated.
