Asymmetric structural composite development and EMI shielding mechanisms are reviewed. The structure and properties of multi-layered, porous, fibrous, and segregated asymmetric structural EMI shielding composites are accurately described. Nano-fillers with different magnetic, electrical and dielectric properties play a decisive role in the asymmetric EMI shielding composites are also described.

In the Brønsted acid-catalyzed stereoselective cationic RAFT polymerization, even though the stereoselectivity of the polymerization is mainly governed by the bulky anion derived from the acid catalyst (PADI), the RAFT agent was also found influential. High isotacticity (up to 90% m) was achieved by optimizing the RAFT agents.

In this study, we present the introduction of triclosan-conjugated, lipase-responsive polymeric micelles. These micelles are specifically designed to harness the unique properties of biofilms and function as a responsive drug delivery platform. The micelles are formed through the synthesis of an amphiphilic block polymer via ring-opening polymerization of ε-caprolactone (CL) and cyclic trimethylene carbonate (MTC-Tri) containing triclosan.

Polymer-feature properties were focused to explain the characteristics of three Broussonetia species for the pulping processing, while the fiber rigidity method based on the Kratky-Porod chain model was improved and further reveals the influencing factors of fiber rigidity.

Microcellular PLA foam was fabricated through a core-back microcellular injection molding technique with the addition of HNA. The obtained PLA/HNA blend foam displayed a crystallinity as high as 55.7%. The tensile toughness of PLA blend foams demonstrated a remarkable improvement of 463%. The PLA/HNA blend foam demonstrated exceptional thermal resistance.

Adjustable and reprocessable hindered urea bonds containing thermosets and their composites with modified ZnO nanoparticles were fabricated via UV curing.

A dielectric ink with favorable properties for inkjet 3D printing was formulated. An internal dual three-dimensional cross-linked network structure resin was prepared by a combination of photocuring and thermal curing. These can be applied to the 3D printing of printed circuit boards and other electronic devices that require dielectric properties.

When PLLA/PP binary blends crystallize from the melt, the crystallization rate of PP is limited, while the crystallization rate of PLLA is accelerated. When PLLA crystals are present in the co-mingled system, the crystallization rate of PP can be substantially increased.

In the present work, (3-thiopropyl)polysilsesquioxane SSQ-SH was introduced into a polylactide. Thermal and mechanical characterization was carried out, as well as a rheology test. The formation of spherulite structures was observed. Particularly noteworthy is the fact that SSQ-SH significantly improves the impact strength of the composite.

The self-healing elastomers with tunable size of separated phase domain were successfully fabricated through reversible addition-fragmentation chain transfer polymerization without changing the proportion of monomers.

The conductivity of the P3HT ultrathin films prepared on glass, Si wafers and ITO substrates was similar, yet the stretchability of P3HT ultrathin films on ITO substrate is better than that on the other two. The polar component of surface energy plays a critical role on the crystalline and morphology of P3HT ultrathin film, further determining its electronic and mechanical performances.

In this work, crude carbon dots (CCDs) were used as multifunctional additives for natural rubber/silica system. The results revealed that the CCDs could endow the rubber compound with excellent anti-aging capability, higher curing rate, better mechanical performance, lower rolling resistance and effectively reduce the ZnO dosage by at least 40%.

Synthesised fluorescent and multi-responsive polyethyleneimine (RFPEI) exhibits both LCST and UCST properties in water and stimuli-adjustable fluorescence emission. Its fluorescence properties and phase transition process are examined systematicly. RFPEI shows great potential for cell imaging, trace detection, and controlled release of doxorubicin.

In pursuit of an ideal emulsion separation membrane that combines high separation efficiency and mechanical properties, a bilayer compounded membrane was fabricated by electrospinning polytetrafluoroethylene (fPTFE) emulsion onto an ePTFE substrate. The compounded membrane possesses the superior separation performance of fPTFE alongside the mechanical properties of ePTFE, showing comprehensive performances.

To enhance the mechanical properties of PPR, PS was added to the PPR matrix. Then PPR/PS MFC with different blending ratios were prepared using MFVIM technology. The results indicated that V-20PS sample had a large number of shish-kebab and hybrid shish-kebab structures and the mechanical properties were significantly improved.

In this study, highly conductive composite rubber was prepared by dopamine-assisted electroless silver plating plus mechanical mixing. Thanks to the advantages of low density, high aspect ratio and high conductivity of the silver-plated carbon fibers, the EMI shielding effectiveness of the composite rubber filled with 45 phr of silver-plated carbon fibers reached 111 dB.

Illustration: Leveraging Voronoi tessellation and particle stresses, we visualized the stress distribution within the stretched cross-linked network, and investigated the relationships between Voronoi volume, bond length, bond angle, and their corresponding local stresses, elucidating the role of different types of local structures in controlling the mechanical properties of the cross-linked network.

Under the driving of the tangential active force, the part of polymer inside the circular cavity adopts random coil configuration at small polymer rigidity and spiral configuration at moderate or large polymer rigidity, resulting that the injection time shows nonmonotonouse dependence on the polymer rigidity.
