In this study, we designed a water-soluble, cell-penetrating, dual redox-active polymer (pMBFcAq) containing ferrocene (Fc) and anthraquinone (Aq) units. pMBFcAq retained the redox activity originating from the Fc and Aq units and induced oxidative stress and cell death more strongly against mouse colon cancer CT26 cells than polymers containing either Aq or Fc units alone. The in vitro anticancer activity of pMBFcAq was enhanced by adjusting its composition.

The efficiency of macroscopic functions, such as healability and recyclability, correlates with the relaxation rate at the molecular level, which is determined by the frequency of bond exchange. While recent studies have extensively examined the influential network factors affecting the relaxation rate, the impact of glass transition temperature (<i>T</i>_g) has been rarely studied. In this work, we fabricated poly(acrylate)-based CANs with varying <i>T</i>_g values by utilizing acrylate monomers with different alkyl side lengths. In our design, bond exchange occurs via disulfide exchange, with tertiary amino groups chemically attached to serve as internal catalysts. We initially hypothesized that the relaxation rate would be higher for the samples with a low <i>T</i>_g due to increased strand mobility. Interestingly, this expectation is not valid at temperatures significantly higher than the <i>T</i>_g; the samples with a higher <i>T</i>_g exhibited a higher relaxation rate. This finding can be interpreted in terms of effects of steric hindrance and the polarity of the alkyl side groups on the diffusion of exchangeable units and the catalytic units.

In this study, we propose principles for modulating these optical properties based on the opposite birefringence signs between benzenoid groups and hydroxyl and the polymer chain arrangements induced by sequential (SEQ) biaxial stretching. Diverse PVAc derivatives, including poly(vinyl benzyl acetal) (PVBA), poly(vinyl 4-fluorobenzyl acetal) (PVFBA), and poly(vinyl <i>p</i>-methylbenzyl acetal) (PVMBA), were synthesized through the condensation of poly(vinyl alcohol) (PVA) with various aromatic aldehydes: benzaldehyde (BA), 4-fluorobenzaldehyde (FBA), and <i>p</i>-tolualdehyde (MBA), respectively. SEQ biaxial stretching was performed on these films, clearly mapping out the relationships between composition, processing conditions, birefringence, and wavelength dispersion. The results indicate that altering the type of benzenoid side groups and varying the mol % of vinyl acetal (AC) from 30% to 50% does not affect the positive intrinsic birefringence pattern of the modified PVAc derivatives. Upon SEQ biaxial stretching, samples with higher λ_<i>y</i> for a given λ_<i>x</i> exhibited lower Δ<i>n</i>_in and higher Δ<i>n</i>_th. The three-dimensional refractive index, calculated from Δ<i>n</i>_in and Δ<i>n</i>_th, changed accordingly: at constant λ_<i>x</i>, elongation in the <i>y</i>-direction increased <i>n</i>_<i>y</i> while decreasing <i>n</i>_<i>x</i> and <i>n</i>_<i>z</i>, resulting in a refractive index order of <i>n</i>_<i>x</i> &gt; <i>n</i>_<i>y</i> &gt; <i>n</i>_<i>z</i>. This transformation was attributed to the breakdown of single-direction orientation and alignment of polymer chains parallel to the film surface during biaxial stretching, as confirmed by polarized IR spectra. Furthermore, regarding wavelength dispersion, PVBA and PVFBA exhibit extremely flat wavelength dispersion with <i>n</i>_<i>x</i> &gt; <i>n</i>_<i>y</i> &gt; <i>n</i>_<i>z</i>, and are suitable for use as compensation films in vertical alignment liquid crystal displays (VA-LCDs).

It was verified that GO did not modify the hydrophobicity and crystallinity degree of PBAT. The reduction of molecular weight due to GO incorporation was verified, and it could be the main reason for the observed decrease in tensile strength and increase in elongation.

The elongation and tenacity were also improved by 90% and 33%, respectively, for the highest concentration of GO (0.25%). Besides, GO at 0.25% accelerated the mineralization rate of PBAT in soil, probably due to the lower molecular weight of nanocomposites in relation to the neat polymer. The preliminary information obtained in this work indicates that the level of PBAT hydrolytic degradation during the extrusion process was not high enough to avoid its application in food packaging because the obtained thermal, mechanical, and ultraviolet (UV) barriers still indicate an exciting balance of properties for this purpose, which can even be improved with future research.</p>","PeriodicalId":7,"journal":{"name":"ACS Applied Polymer Materials","volume":"7 8","pages":"5229–5239 5229–5239"},"PeriodicalIF":4.4,"publicationDate":"2025-04-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://pubs.acs.org/doi/epdf/10.1021/acsapm.5c00536","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143867376","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To address these limitations, rosin and functional rosin esters, sourced from pine trees, were blended with HTPB at loadings up to 20 wt % prior to cross-linking with toluene diisocyanate. All rosin esters studied were shown to be fully miscible with HTPB; a single glass transition temperature (<i>T</i>_g) was measured for all HTPB/rosin ester blends slightly above the <i>T</i>_g (−79 °C) of HTPB and well below that of the rosin esters (38–58 °C). Simultaneous wide-angle X-ray scattering (WAXS) and small-angle X-ray scattering (SAXS) measurements confirmed that there was no phase separation between the HTPB and rosin esters when blended.

Orienting the filler for alignment is the most widely adopted approach to enhance TC in these materials. However, traditional orientation strategies require external fields or additional conditions, resulting in complex processes and hindering the ability to achieve conformal orientation of heterogeneous structures. In this context, an orientation strategy is proposed based on dense packing and injection molding to fabricate high-orientation and shape-controllable composites, thereby reducing limitations related to temperature, pressure, molding shapes, and matrix types during composite preparation. Dense packing induces the transition of high diameter-to-thickness ratio (DTR) fillers from locally isotropic to anisotropic alignment, while the injection molding process drives the overall orientation of the composites. Using aluminum (Al) flakes and cyanate ester (CE) as representative materials, a systematic study was conducted on the influence of filler content and composite thickness on the orientation of fillers. As a result, Al/CE-40 exhibits remarkable flexibility and achieves a maximum tensile strength of 29.9 MPa with an Al flake content of 40 wt %.
