From the assumption of constant thermo-physical properties, an approach permitting the exact solution of a 1D unsteady heat conduction problem involving variable thermal properties, was introduced and tested for CPCs. Starting from these theoretical results, a method aimed at preliminary retrieving the in-plane and out-plane thermal diffusivity of CPCs through the Oxy-Acetylene Torch (OAT) tests was validated.

Herein, the ester of <em>N</em>-hydroxysulfosuccinimide activated lauric acid (NHSS-LA) was prepared as a promising alternative hydrophobic modifier, which could be efficiently used in aqueous solutions for enhancing the structure and properties of HMCs and hydrophobically modified collagen fiber membranes (HMCFMs). The performance of HMCs and HMCFMs could be tuned through adjusting the dosages of NHSS-LA. Besides maintaining the triple helical structure and cytocompatibility of HMCs, the hydrophobic modification could improve the thermal stability of HMCs owing to the enhancement of hydrophobic associations between collagen molecules, which was closely related to collagen concentrations and modification rates. Furthermore, the water resistance, thermal stability, and enzymatic degradation stability of HMCFMs were significantly improved.

As a result of exposure to drinking water containing ClO<sub>2</sub>, practical experience has demonstrated that the lifetime of PE pipes can be significantly reduced, and PE pipes in water distribution systems may prematurely fail due to chemical degradation. In this research, the effect of co-monomer type and distribution upon the stability of PE pipes against water-containing ClO<sub>2</sub> has been explored.

Therefore, the higher crystalline a polymer is, the slower the kinetic of degradation against ClO<sub>2</sub> will be. Moreover, the strong chain entanglement in amorphous phase, suppress the crack growth and enhance the resistance of the pipe against chemical degradation. Consequently, AS-80 resin, which has 1-hexene co-monomers and the uniform distribution of comonomers, exhibits higher stability against ClO<sub>2,</sub> as a result of its higher crystallinity and strong chain interaction in amorphous region, and it is preferable in drinking water-containing ClO<sub>2</sub> pipe systems.</div></div>","PeriodicalId":406,"journal":{"name":"Polymer Degradation and Stability","volume":"232 ","pages":"Article 111154"},"PeriodicalIF":6.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143182804","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}

However, most of the MPs used in previous studies are from virgin materials through artificial granulation, as it is almost impossible to collect the natural MPs from nature and accurately identify their sources or ages. It is anticipated that the MPs after UV aging possess some major distinct characteristics similar as aged in nature, including variations in molecular weight, molecular weight distribution, surface chemicals. This study systematically investigated both virgin and UV aged samples derived from the most prevalent sources, including polyethylene (PE), polypropylene (PP), poly(ethylene terephthalate) (PET), polystyrene (PS), and poly(vinyl chloride) (PVC), focusing on the effects of the artificial digestion system on the MPs. Additionally, the study evaluated the impact of these MPs on health by examining their effects on probiotics within the digestive system. The results demonstrate that both the effect of digestion treatment MPs and the impact of MPs on intestinal microbiota are significantly different between virgin and aged MPs. While digestion processes were ineffective in degrading virgin MPs, primarily due to their chemical inertness, the surface changes in MPs were more pronounced after UV aging, though they remained largely unaffected by digestion. The surface chemical changes were significant during aging but not during digestion. On the other hand, certain MPs, particularly PVC, may disrupt the balance of intestinal microbiota, especially from aged samples.</div></div>","PeriodicalId":406,"journal":{"name":"Polymer Degradation and Stability","volume":"232 ","pages":"Article 111157"},"PeriodicalIF":6.3,"publicationDate":"2025-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143182811","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}

By simplifying the complex degradation evaluation into a straightforward framework of compositional analysis, a comprehensive degradation metric can be obtained without tracking individual degradation pathways. Moreover, by including stabilizers as system components, stabilizer leaching and polymer degradation can be concurrently visualized in the same framework. We demonstrate this approach in polyurethane films subjected to accelerated degradation tests and, by correlating the CDP-defined degradation metric with mechanical property evaluations, successfully identify the threshold degradation level that marks a material's end-of-life. Furthermore, this method reveals deeper insights into degradation mechanisms: stabilizer leaching and polymer degradation are complementary processes that induce each other.
