Networks obtained via three different cross-linking reactions are compared. This concerns two oxazinone-amine reactions with different reaction rates and the carboxy-amine reaction activated by CDI. Reaction parameters such as temperature, concentration, and solvent, as well as the molar masses of the stars used, are comparable. For the ACNs, equilibrium volume swelling degrees <i>(Q_v)</i> are determined. Information about the micro structure of the ACNs (connectivity distribution) is obtained from proton low-resolution multiple-quantum NMR investigations. Although the coupling reactions differ distinctly in terms of reaction speed and coupling mechanism, ACNs with similar properties are obtained. In multiple determinations with de- and re-swelling cycles, a reduction in the <i>Q_v</i> values is observed, which indicates that the reaction progresses in the dried state of the samples. The connectivity distributions determined by multiple quantum NMR show for all ACNs distinct deviations from a statistical distribution. This can be seen by the fact that double and triple links are formed preferably between neighboring stars. This distinguishes ACNs from tetra-PEG networks described in the literature, for which a statistical distribution is found.

Incorporation of HPM introduces phenolic and maleimide functionalities onto NR chains, enabling enhanced interfacial interactions with phenolic-modified polypropylene compatibilizers (PhHRJ-PP and PhSP-PP). Compared with PP-g-MA, phenolic compatibilization in the NR-g-HPM/PP (60/40) system produced higher plateau mixing torque, superior tensile strength, lower tension set, and significantly refined rubber morphology. The PhHRJ-PP-compatibilized TPV exhibited the finest rubber dispersion, with an average domain size of ≈2.2 µm, which is substantially smaller than that of the uncompatibilized control (≈4.0 µm) and the PP-g-MA-compatibilized system (≈6.1 µm). This refined morphology resulted in a higher storage modulus and reduced viscous dissipation. When varying the blend ratio, the 50/50 NR-g-HPM/PP composition delivered the optimum balance of properties, achieving the highest tensile strength (15.86 MPa), lowest permanent deformation, and finest rubber dispersion (≈2.0 µm).

This work developed a nanomaterial-assisted mussel-inspired poly (m-phenylene isophthalamide) (PMIA) loose NF membrane with high permeability and excellent dye/salt selectivity. During fabrication, polyethyleneimine (PEI) was incorporated into the dopamine solution to promote uniform polymerization of dopamine, enhancing the homogeneity of the coating layer. Meanwhile, various titanium dioxide (TiO₂) nanoparticles were incorporated into the mussel-inspired solution to enhance membrane performance. The addition of TiO₂ increases the available free volume in the membrane's thin selective layer, thus enhancing the permeation of water molecules. The modified membrane demonstrated remarkable flux (153.77 L·m⁻²·h⁻¹·bar⁻¹), a Congo red (CR) rejection exceeding 98%, and a favorable CR/Na₂SO₄ selectivity of 29.6. Notably, other nanoparticles, such as graphene oxide (GO), halloysite nanotubes (HNTs), silica (SiO₂), zeolitic imidazolate framework-L (ZIF-L), and polydopamine (PDA) modified silver (Ag), can also regulate the PDA-PEI coating structure, thereby synergistically enhancing the membrane's permeability.

This study investigates the self-assembly of a multistructured rod-coil diblock copolymer consisting of poly(L-proline) and polystyrene (PS) segments. The unique feature of these diblock copolymers is that the secondary structure of polyproline (PLP) blocks can independently be tuned into two distinct conformations (PPI and PPII). Furthermore, a high energy barrier associated with the conformational transition between PPI and PPII structures makes it of interest to study the influence of secondary structure on self-assembly under thermodynamic equilibrium. A pair of diblock copolymers (PS_m-<i>b</i>-PLP_n) with differing polyproline block lengths has been synthesised. Among the two PLP-containing block copolymers examined, the diblock with a trans-polyproline (PPII) segment self-assembled into a well-defined lamellar morphology.
