However, these materials are highly flammable, which has led to numerous fire accidents. Therefore, it is necessary to study the fire risk of thermal insulation materials. The combustion performances of three commonly used materials, namely expanded polystyrene (EPS), extruded polystyrene (XPS) and polyurethane (PU), were measured through cone calorimeter experiments. Subsequently, the entropy method was employed to quantitatively assess the fire risk of the three insulation materials, and the fuzzy cluster analysis method was used to classify the 17 parameters that characterized fire hazards. The results showed that EPS and XPS had similar combustion characteristics, which were different from those of PU. The comprehensive index values of EPS, XPS, and PU evaluated by the entropy method were 0.11–0.15, 0.32–0.71, and 0.14–0.57, respectively. It indicated that EPS had the lowest fire hazard, XPS had the highest fire risk, and the fire risk of PU was between EPS and XPS. The clustering analysis results indicated that there were a total of 14 thresholds representing fire risk, corresponding to 14 distinct scenarios. Under each determined threshold condition, correlations could be established between these parameters, including both differences and similarities. This study can provide a basis for the selection of building insulation materials and a reference for the classification of material parameters.</p></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"82 14","pages":"9227 - 9243"},"PeriodicalIF":4.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145237006","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This paper offers an extensive exploration of the diverse landscape of bioplastics, addressing their production, characteristics, and environmental implications. Since bioplastics are produced from renewable biomass sources including, proteins, starch, and algae, they provide a sustainable alternative to conventional plastics. The pressing need to reduce plastic waste and our dependence on finite fossil fuels is what drives the need for bioplastics, which aligns with global sustainability objectives. The paper comprehensively overviews various bioplastics. It emphasizes their renewable feedstock sources and potential to reduce dependence on finite fossil fuels. The environmental impact of bioplastics was analyzed, highlighting their carbon footprint, biodegradability, and resource efficiency. Techniques for bioplastic degradation, such as biological, enzymatic, chemical, and thermal methods, were explored, highlighting the diverse approaches to managing bioplastics' end of life. These include land use competition with food crops, energy-intensive production processes, and variable degradation rates depending on environmental conditions. Technological limitations, such as scalability, performance under industrial processing conditions, and higher production costs compared to conventional plastics, are also critically discussed. However, while bioplastics offer several environmental advantages, such as biodegradability and the use of renewable feedstocks, it also comes with trade-offs. The study emphasizes the potential of bioplastics to reduce plastic pollution and support a sustainable circular economy by looking at their life cycle from manufacture to breakdown. Overall, this paper indicates bioplastics as a crucial component in the fight against plastic pollution, promoting a more sustainable and eco-friendly future.</p></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"82 14","pages":"8871 - 8953"},"PeriodicalIF":4.0,"publicationDate":"2025-06-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145237007","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In this review, we provide a comprehensive overview of the polymerization strategy used for synthesizing star polymers, multi-initiators that give rise to the number of arms, and cross-linkers, which are subsequently used to prepare polymeric hydrogels. The hydrogels prepared from star-shaped polymers were classified into four groups according to the cross-linking strategy and physicochemical properties: supramolecular hydrogels, amphiphilic polymer conetwork hydrogels, double-network hydrogels, and cross-linked hydrogels. Besides biocompatibility, hydrogel applications require advanced mechanical properties that are significantly affected by cross-linking defects introduced in the network structure during the gel preparation, limiting a large variety of hydrogel applications.

Modulus enhancement can be achieved by optimizing the chemical cross-linking conditions such as treatment temperature during hydrogel synthesis. This study investigates the influence of temperature on the properties of chitosan and oxidized pullulan (CS/APUL) hydrogels via chemical crosslinking for biomedical applications. Fourier transform infrared spectroscopy, thermal analysis, scanning electron microscopy, and rheological analysis were used to examine the physicochemical properties of CS/APUL hydrogels. The results demonstrate that temperature significantly affects the onset gelation time, gel fraction, and gel strength of CS/APUL hydrogels. As the temperature increased from 25 to 45 °C, the gelation time decreased from 117.25 ± 4.40 to 21.3 ± 1.10 s, indicating faster crosslinking and network formation. Concurrently, the gel fraction and complex modulus (gel’s strength) of the hydrogels increased from 56 to 68%, and 893.57 ± 33.7 to 1779.75 ± 72.7 Pa, respectively, suggesting enhanced mechanical stability and structural integrity at higher temperatures. Conversely, the swelling ratio of the hydrogels decreased with rising temperature, likely due to the formation of a denser and more tightly crosslinked network. These findings highlight the tunability of CS/APUL hydrogels through temperature control, making the biomaterials promising candidates for applications such as drug delivery, tissue engineering, and wound healing, where precise mechanical and swelling properties are crucial.</p><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"82 14","pages":"9089 - 9105"},"PeriodicalIF":4.0,"publicationDate":"2025-06-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145236894","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
