Specifically, using a 70 wt%/30 wt% PLA/TPU matrix and an L₉(3²) orthogonal design, composites were evaluated <i>via</i> morphology, shape memory, mechanical tests, and multi-criteria analysis. Moderate DCP enhanced crosslinking, improving storage modulus and thermal stability, while excessive DCP caused brittleness.

Consequently, Sample 5 achieved optimal performance, exhibiting uniform fracture morphology, a shape fixation rate of 98.8% with the fastest recovery, and balanced strength-ductility. Multi-criteria analysis identified elongation at break and recovery time as the top contributing factors, with consistent rankings validated by Spearman analysis (<i>ρ</i>=0.833, <i>p</i>&lt;0.01). In summary, adjusting DCP and MAH-<i>g</i>-PE contents effectively modulates the crosslinking structure and interfacial properties of PLA/TPU composites, providing a viable strategy for developing high-performance, tunable 4D printing materials.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"44 4","pages":"1069 - 1082"},"PeriodicalIF":4.0,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147667812","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}

Ionizable amphiphilic Janus dendrimers (IAJDs) represent a promising class of carriers; however, their structural complexity and limited available datasets hinder systematic exploration and optimization. In this study, we established a tailored machine-learning framework to investigate the structure-function relationships of IAJDs under a constrained data regime (<i>n</i>=231). Conventional molecular fingerprints were found to be suboptimal for representing these macromolecules, motivating the adoption of count-based descriptors and systematic ablation analyses to disentangle the contributions of the substructural features. These experiments identified key functional motifs underlying transfection performance and provided interpretable insights into the IAJD design principles. Complementing these handcrafted descriptors, we further applied deep learning-based molecular embeddings, which captured higher-order chemical semantics and significantly improved predictive accuracy. Collectively, these advances demonstrate that both refined fingerprinting and representation learning approaches can overcome data limitations, enabling the reliable prediction of IAJD activity while offering mechanistic interpretability. This study illustrates the potential of data-driven strategies as hypothesis-generation and prioritization tools for the design of next-generation mRNA delivery systems.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"44 4","pages":"1154 - 1164"},"PeriodicalIF":4.0,"publicationDate":"2026-03-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147667797","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}

The effects of the PPC content (0 wt%–50 wt%) on the phase morphology and performance of the blends before and after pre-stretching were systematically investigated. Blending PPC initially reduced the strength, modulus, and heat resistance, but pre-stretching significantly enhanced these properties. In blends containing ≤30 wt% PPC, where PPC formed a well-dispersed island-like phase within the PLA matrix, pre-stretching simultaneously enhanced strength, toughness, and heat resistance. The optimized pre-stretched 70/30 PLA/PPC (ps-70/30) blend achieved exceptional performance: tensile strength increased from 66.9 MPa to 84.5 MPa, elongation at break dramatically improved from 6.8% to 115.1%, impact strength reached 55.1 kJ/m² (far exceeding neat PLA’s 3.5 kJ/m²), and Vicat softening temperature (VST) increased by 60.6% to 101.8 °C. Notably, the ps-70/30 blend retained excellent mechanical properties even after six months of aging. These improvements were attributed to the synergistic effects of the PPC incorporation and pre-stretching. PPC not only promoted the high orientation of the PLA molecular chains but also facilitated the formation of a stable crystalline phase during pre-stretching, thereby enhancing both the mechanical properties and heat resistance. However, when the PPC content exceeded 30 wt%, phase inversion occurred, resulting in a continuous amorphous PPC phase that degraded the overall performance. This study demonstrated that a combination of controlled PPC incorporation and pre-stretching can effectively overcome PLA’s brittleness of PLA while improving its heat resistance, offering a promising strategy for developing high-performance, fully biodegradable PLA materials suitable for industrial applications.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":517,"journal":{"name":"Chinese Journal of Polymer Science","volume":"44 4","pages":"1142 - 1153"},"PeriodicalIF":4.0,"publicationDate":"2026-03-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147667795","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}
