In this study, this extraction process was reproduced by leaching a thermally annealed SBR layer deposited on a Si substrate in toluene at room temperature, where the adsorption layer of the SBR was grown at the interface with the substrate by thermal annealing. The SBR adsorption layer on the Si substrate has two-layer structures consisting of an inner and outer adsorption layers, which correspond to the tightly and loosely bound rubbers on the filler surface of the silica-filled SBR, respectively. For the sample annealed for less than 6 h, the outer adsorption layer, loosely bound to the substrate, was easily leached in toluene for 5 min, leaving only the inner adsorption layer on the substrate. For the samples annealed for more than 24 h, a large portion of the outer adsorption layer remained on top of the inner adsorption layer as a terrace structure. However, even for the sample annealed for 24 h, treating with toluene for 24 h completely leached the outer adsorption layer from the inner adsorption layer, although the inner adsorption layer remained on the substrate. It was found that the loosely bound rubber in the silica-filled SBR could be easily extracted from the filler surface, along with the free polymer chains in the polymer matrix during extraction with toluene at room temperature. In contrast, the tightly bound rubber was not leached by toluene at room temperature. This may be because the interfacial polymer chains within approximately 1 nm of the substrate surface were strongly constrained to the substrate, and even toluene molecules were excluded.</div></div>","PeriodicalId":405,"journal":{"name":"Polymer","volume":"333 ","pages":"Article 128662"},"PeriodicalIF":4.1,"publicationDate":"2025-06-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144237019","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

These materials exhibited remarkable efficiency in adsorptive capture of PGM ions, even at low concentrations (1 ppm). Notably, at 10 ppm, PPN3, with its distinct surface area and porous structure, outperformed PPN1 and PPN2. Furthermore, in acidic environments, protonation enhanced selectivity of PPN3 for PGM ions (Ru, Pd, Pt) over rare-earth (La, Ce, Nd) and transition metal ions (Cu, Ni, Co, Mn) in a multicomponent system, driven by electrostatic interactions between the PGM ion speciation with protonated amino groups. Additionally, we successfully engineered PPN3 nanoparticles into robust, stable, and scalable beads while maintaining their exceptional PGM adsorption capabilities in complex metal ion mixtures, demonstrating their potential for practical applications.

To address this limitation, this study proposes a molecular design strategy integrating covalent crosslinking and conjugated conductive networks. Based on this, a new diamine monomer (4-POPDA) containing pendant pyrrole rings was synthesized and polymerized with 4,4'-(hexafluoroisopropylidene) diphthalic anhydride (6FDA) to form poly(amic acid) (4-POPPAA). A suspension of ionized 4-POPPAA, pyrrole monomers, and dopant was electrophoretically deposited. During this process, the 4-POPPAA film was electrodeposited, and at the same time, the pendant pyrrole rings on the 4-POPPAA chains electrochemically polymerized with the pyrrole monomers in the suspension to form a covalently crosslinked polypyrrole (PPy) network. The obtained crosslinked 4-POPPAA-PPy film was then chemically imidized to form crosslinked 4-POPPI-PPy film. With the formation of long-range conjugated PPy network, the obtained 4-POPPI-PPy film presented a high electrical conductivity of 15.82 S/cm.

Furthermore, the crosslinked 4-POPPI-PPy film had excellent high-temperature conductivity retention and favorable mechanical properties. After annealing at 250 °C, the crosslinked 4-POPPI-PPy film still had a conductivity of 7.52 S/cm, while the pure PPy lost its conductivity.

Herein, we report selective infusion templating (SIT) inside ordered gels to achieve composition-insensitive and tunable synthesis of ordered gyroidal polymer hybrids and mesoporous carbon monoliths. Our SIT strategy involves the chemically confined polymerization of a carbon-forming polymer inside a nanostructured bulk organogel with gyroid morphology, which enables quantitative infusion efficiency to achieve percolated in-gel polymerized hybrids and continuous self-standing monolithic carbon nanonetworks. Dry and gel-state small-angle X-ray scattering confirms the formation and retention of a well-ordered gyroidal morphology during every step and demonstrates that fine-tuning of structural parameters is possible through the infusion composition without changing the ordered morphology. The distinct chemical interactions between the gel template and components of the infused reagent solution offers a complementary design principle and alternative bottom-up fabrication strategy for ordered hybrid and mesoporous materials with tailored architectures.
