Summary: This study proposes a novel strategy for preparing form-stable phase change materials using polyethylene glycol (PEG) and polyvinyl formal (PVF) in a foam structure. The PEG/PVF composites exhibit good performance in terms of phase transition enthalpy, residue amount, and thermal degradation temperature.

Summary: This study reports the fabrication of nanocomposites with a poly(benzoxazine-co-epoxy) matrix reinforced with 1 wt% graphene. The addition of single fillers caused a delay in polymerisation and an increase in exothermic peak temperature, resulting in a reduction in ΔH-Total. Copolymerisation led to a decrease in tensile modulus and strength compared to the neat copolymer, while the nanocomposite with 0.7 wt% Nanene-002 + 0.3 wt% Nanene-001 showed the highest increase in tensile strength and elongation at break. Additionally, the thermal stability of the materials was improved.

Summary: Melt blending is an effective method for preparing new composite materials, but most polymers are incompatible. By adding suitable compatibilizers, the interfacial tension can be reduced and fine and stable morphology can be obtained. In this study, LDPE/PS composites were compatibilized using SEBS-g-MAH and OMMT, leading to improved compatibility and enhanced mechanical properties.

Summary: In this study, PLA/ABS blends compatibilized with SEBS-g-MA were prepared using a co-rotational twin-screw extruder. The influence of the compatibilizing agent on the properties of the blends was analyzed, including morphology, mechanical, thermal, thermomechanical, and rheological properties. The results showed that the addition of SEBS-g-MA significantly improved the impact strength of the blends. Annealing also played a role in increasing the crystallinity and heat deflection temperatures of the blends. The study suggests that the PLA/ABS/SEBS-g-MA system has potential for use in 3D-printing filaments.

Summary: In this study, nanocomposites of polylactic acid (PLA) with clove essential oil (CEO) and alkali treated halloysite nanotubes (NHNT) were synthesized. The nanocomposite films showed enhanced physical, thermal, mechanical and water vapor barrier properties. Practical packaging tests on apples stored at room temperature showed substantially improved results compared to PLA in terms of weight loss, microbial count, firmness, acidity, pH, and total soluble solids. The results demonstrate the potential of PLA/CEO/NHNT nanocomposite films as active food packaging material.

Summary: The incorporation of talc reduces the stiffness of composites, while the addition of graphene oxide and SEBS-g-MAH significantly improves the mechanical and thermal properties of ABS polymer matrix. ABS/talc composites prepared through melt mixing showed increased tensile strength, flexural strength, and flexural modulus, as well as comparable impact strength to ABS. The addition of GO and SEBS-g-MAH also provided higher thermal stability for both composites with and without talc.

Summary: The crystallization kinetics of poly(butylene terephthalate) under high supercooling was investigated using Temperature-Modulated Fast Scanning Calorimetry (TM-FSC). The study found a temperature dependence of crystal growth rate and compared it with the peak time of heat flow during isothermal crystallization. The crystal growth rate was found to be practically determined by a mobility factor near the glass transition.

Summary: By analyzing different grades of PDLLA using fast scanning calorimetry, it is found that the glass transition dynamics of PDLLA and PLLA are essentially the same, suggesting that stereoisomerism does not influence the glass transition dynamics.

Summary: The correlation between the dispersion quality of PEG-grafted silica nanoparticles and the crystallization ability of PEO nanocomposites was systematically investigated, revealing that high sigma and low P/N conditions can increase the nucleation rate of PEO. This study highlights the importance of nanoparticle dispersion and grafting characteristics in influencing the crystallization behavior of polymer nanocomposites, leading to novel and unexpected results.
