Yet, due to its relatively recent implementation in construction, little is known about its long-term degradation behavior in building contexts. Herein, we analyzed the degradation mechanisms of silicone sealants exposed to more than three decades of natural weathering in a high-rise tower façade. Our findings revealed that acid rain is the most detrimental factor to the silicone material – leading to the dissolution of the filler particles and inducing hole defects and microscale cracking. At a slower rate, the weathering exposure also led to the deterioration of the silicon-carbon atomic structure. The observed degradation led to a marked decrease in elongation capacity and an increase in the modulus of elasticity of the material. Nonetheless, the visual appearance and mechanical properties of the weathered sample still conformed with performance standards – reiterating the excellent durability of silicone in building assets. Overall, the obtained knowledge serves as a reference for future weathering studies on silicone and similar elastomeric materials as well as guide future façade design and inspection guidelines.</div></div>","PeriodicalId":406,"journal":{"name":"Polymer Degradation and Stability","volume":"236 ","pages":"Article 111299"},"PeriodicalIF":6.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143580432","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}

However, MXene easily agglomerates in polymeric materials and has significant limitations in compatibility with hydrophobic polymers, resulting in the impairment of their mechanical properties and greatly hindering the improvement of their flame retardant properties. In this study, in order to improve the interfacial compatibility of the flame retardant with EVA, we prepared a Ti₃C₂Tx/MgAl LDH/PDA-Fe composite flame retardant by loading iron-loaded polydopamine (PDA-Fe) on the surface of Ti₃C₂Tx/layered double hydroxide (MgAl LDH) using polydopamine as an adhesive. Due to the strong adhesion of PDA, the interfacial compatibility between the flame retardant and EVA was greatly improved. And the hydrophobicity of Ti₃C₂Tx/MgAl LDH/PDA-Fe was greatly enhanced with a water contact angle value of 88.6°, which further enhanced the flame retardant properties of the EVA composites. The peak heat release rate of the EVA composites with the addition of 5 wt% Ti₃C₂Tx/MgAl LDH/PDA-Fe was 659.7 kW·m⁻², which represented a 29.1 % decrease compared to that of Neat EVA. In addition, the MgAl LDH inhibited the accumulation of Ti₃C₂Tx in EVA, and their synergistic effect improved the fire safety of EVA composites. Thus, this study provides a new paradigm for the preparation of hydrophobic flame retardants capable of improving interfacial compatibility with EVA, which has a promising application.</div></div>","PeriodicalId":406,"journal":{"name":"Polymer Degradation and Stability","volume":"236 ","pages":"Article 111297"},"PeriodicalIF":6.3,"publicationDate":"2025-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143552906","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}

Therefore, there is an urgent need to find effective and sustainable methods for plastic degradation, especially polyethylene, the most manufactured polymer globally. Here, we emulate the strategies documented for beetles, characterized by a combination of physical, chemical, and microbiological treatments, to biodegrade low-density polyethylene (LDPE). Importantly, we characterize LDPE degradation through multiple techniques, including weight loss analysis, FTIR, GPC, GC–MS, and SEM, which allowed us to identify the optimal combination of treatments to enhance LDPE biodegradation. Contrary to some expectations, we find that ultrasonication does not contribute to LDPE degradation but may instead protect against its fragmentation. However, we successfully introduce carbonyl groups into the polymer backbone, by simply exposing LDPE to environmentally friendly anionic surfactant. This pretreatment effectively cleaves LDPE by approximately 9%, breaking it into shorter carbon chains that are more accessible to microbes for subsequent biodegradation. The yeast <em>Yarrowia lipolytica</em>, isolated from fuel tanks and able to grow in <em>n</em>-paraffines, not only outperforms other microbes in assays of short carbon chain degradation, but also attaches to the LDPE surface, where it survives and grows using LDPE as sole carbon source.

Addressing this challenge, we developed a novel triazolyl-based cyclomatrix polyphosphazene (HTDA) that self-assembles with melamine cyanurate (MCA) through hydrogen bonding, forming a hybrid flame retardant (HTDA@MCA) with a distinctive lamellar structure.

Firstly, the thermo-mechanical degradation underwent during reprocessing, as well as the different degradation forms experienced during the service life, cause a severe modification of polyolefin microstructure, ultimately leading to a progressive deterioration of their performance. On the other hand, due to non-fully accurate sorting technologies, low levels of cross-contamination are commonly encountered in recycled polyolefins. All these features result in the obtainment recyclates with a heterogeneous and complex morphology, which significantly affects their final properties, often limiting their possible future applications. This work aims at addressing these issues, evaluating the combined effect of cross-contamination and of the degradation undergone by the polymers during service life and reprocessing for high-density polyethylene (HDPE) containing low amounts of polypropylene (PP) and polyethylene terephthalate (PET) as contaminants. In particular, pristine and cross-contaminated HDPE were subjected to photo-oxidative or thermo-oxidative treatments and the aged materials were reprocessed, aiming at simulating the real conditions of a typical mechanical recycling process. The obtained results demonstrated that cross-contamination minimises the functional degradation of HDPE, especially under photo-oxidative conditions. Conversely, the microstructural characterization pointed out that different microstructures can be achieved depending on the level of cross-contamination and on the aging treatment. Finally, it was shown that the presence of PP and PET as contaminants has a detrimental impact on the HDPE ductility, especially under thermo-oxidative conditions, while for photo-oxidised materials exerts a marginal role.</div></div>","PeriodicalId":406,"journal":{"name":"Polymer Degradation and Stability","volume":"236 ","pages":"Article 111290"},"PeriodicalIF":6.3,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143520250","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}
