Summary: The study elaborated PEEK/PES blends with partial miscibility by melt mixing with phenolphthalein, which was confirmed by DSC and DMTA analysis. Phenolphthalein acted as a compatibilizer and plasticizer for the blends, resulting in a softened PEEK phase and improved interfacial adhesion with PES. Additionally, the storage modulus in the glassy region of the blends remained similar to pure PEEK due to the aromatic moieties in phenolphthalein.

Summary: This study investigated the effects of different temperature treatments in air atmosphere on the morphology and properties of basalt fibre (BF). It was found that heat treatment led to the formation of crystals on the fibre surface, changing the properties of BF. The reduction in tensile strength of BF occurred in three temperature ranges: 100-400 degrees C, where the decomposition of organic sizing on the fibre surface exposed more defect structures; 500-600 degrees C, where the amorphous matrix in the fibre experienced phase separation and structural relaxation; and 700-1000 degrees C, where the formation of various crystals caused structural modification.

Summary: In this study, PHB and TEC were blended to investigate the effects of TEC as a plasticizer on the properties of PHB. Increasing the mass fraction of TEC led to gradual changes in mechanical, thermal, and morphological properties of PHB, with TEC acting as an efficient plasticizer. The presence of TEC reduced the glass transition and melting temperatures of PHB, expanded the processing window of temperature, and influenced the crystallization kinetics and morphology of PHB.

Summary: This study evaluates the influences of SBS, NC, and m-SEBS on the non-isothermal crystallization kinetics of PA12 using various theoretical models. The interrelations among the crystallization kinetics variables, morphology, and molecular dynamics of PA12/SBS rubber/NC mixtures were thoroughly investigated. The results show that the PA crystallization rate increases with the compatibilizer level, reaches a maximum value with NC loading and SBS content, and is affected by the heterogeneity of nucleation sites provided by NC platelets and SBS particle surfaces.

Summary: In this study, dairy phospholipid gels were made with varying concentrations of PL to investigate their gel-forming ability and functional properties. Results showed that high concentrations of PL reduced mobility and increased solid fat content, melting enthalpy, and viscosity. Oil binding capacity was significantly affected by PL concentration, indicating that dairy PL can be used to produce semi-solid material with desirable functional properties when added to vegetable oil.

Summary: The physicochemical, structural, and thermal properties of electrospun membranes depend on process conditions and the type and concentration of raw materials. Membranes synthesized using electrospinning with hydrolyzed collagen and polyvinyl alcohol were characterized, showing that morphology is mainly influenced by the polymer/solvent system properties and distance to the collector. Thicker samples with smaller fiber diameters, high porosity percentages, and suitable water vapor permeability values were formed at the furthest distance.

Summary: Functional fillers play a crucial role in thermally conductive polymer-based composites. However, little attention has been given to the impact of functional fillers with the same composition but different morphologies on the crystallinity of the matrix and the final thermal conductivity of the composites. In this study, different forms of boron nitride fillers were mixed with PET resin, and their effects on PET crystallization behavior and thermal conductivity were investigated. The results showed that fillers with different shapes but the same composition had varying modification effects on the crystallinity and thermal conductivity of the composites.

Summary: In this study, PLLA/PCL multi-block copolymers with different compositions were synthesized and introduced into a sc-PLA matrix to accelerate the stereocomplexation of PLA enantiomers and improve its brittleness. The results showed that the introduction of PLLA/PCL multi-block copolymers promoted the stereocomplexation of PLA enantiomers, but the presence of the PCL block decreased the melting temperature and hindered homogeneous nucleation. The blends exhibited significantly improved elongation at break and slightly reduced tensile strength compared to sc-PLA. The thermal stability and mechanical properties of the blends could be adjusted by controlling the content and composition of PCL/PLLA multi-block copolymers.

Summary: This paper discusses the crystallization behavior and thermal properties of polyethylene/wax blends as phase change materials for thermal energy storage. The addition of fillers can have varying effects on the crystallization and melting temperatures of the blends. The lower crystallinity of wax in the blends compared to pure wax affects its effectiveness as a PCM.

Summary: Clay-reinforced polymer composites have been improved by using the 'grafting to' silylation method to enhance their compatibility with thermoplastic polymers. The resulting nanocomposites showed improved performance properties, such as higher tensile strength and Young modulus, better filler dispersion, as well as reduced oxygen and water vapor transmission rates. These nanocomposites could be ideal alternatives for flexible thermoplastic composites as packaging materials.

Summary: In this study, electrically conductive polymer composites were developed by preferentially localizing MWCNTs in a co-continuous EMA/TPO binary blend system. The addition of 3 to 5 wt% of MWCNT achieved the electrical percolation threshold. FESEM and TEM images showed a co-continuous morphology with MWCNTs located in the EMA phase of the blend. The DC and AC conductivity of the composite significantly increased with the addition of MWCNTs. A total EMI shielding effectiveness of -35 dB was achieved by adding 15 wt% MWCNTs into the matrix in the frequency range of 14.5-20.0 GHz, along with good thermal conductivity, dielectric properties, and mechanical properties.
