This study systematically investigates variables influencing particle segregation during solidification in semicrystalline polymers.

Particle distribution can be affected by crystalline phase growth, leading to phenomena like repulsion or segregation. The main objective of this work is to systematically investigate variables contributing to particle segregation during the solidification of semicrystalline polymers, leading to a nonuniform distribution within the polymer matrix. This phenomenon has a direct impact on the properties of semicrystalline polymers, resulting in variations in mechanical, physical, and electrical properties across the polymer matrix. Both isothermal and non-isothermal studies have been conducted to explore significant crystallization parameters, nucleation modes, and crystalline phase growth in the presence of particles. These studies aim to determine the relationship between particle segregation and the altered properties of the polymer matrix. Results revealed the critical importance of a uniform crystal growth mechanism as a prerequisite for the occurrence of particle segregation within polymers.

Because of that, the role of this colorant is expanding to food packaging as intelligent packaging is now becoming the trend for urban lifestyles. In this study, biodegradable packaging from starch-based film incorporated with <i>Brassica oleracea</i> anthocyanin was developed by casting technique. The research focused on optimization strategies, utilizing response surface methodology (RSM) to examine how the concentration of anthocyanin in films, along with buffer pH, temperature, and contact time variables, affects total color difference (TCD) and absorbance values, which are indicative of anthocyanin release. The experiments were designed using a Box–Behnken design (BBD) by applying 29 full factorial designs with five center points. The collected experimental data were used to fit a second-order polynomial equation through multiple regression analysis and were then analyzed using suitable statistical techniques. By utilizing 3-D response surface and contour plots generated from mathematical models, the optimal conditions were identified. The optimum formulation of this anthocyanin incorporated in sago starch films was as follows: anthocyanin concentration 8.2 g, pH of buffer solution 7.9, surrounding temperature 4.1 °C, and contact time 35.8 min. Under these conditions, the films’ reaction produced the highest color difference and lowest absorbance which were 5.7 and 0.0004, respectively. This outcome demonstrates that optimization methods can reduce the release of anthocyanins from starch films, highlighting a significant color variation that enhances its suitability for advanced food packaging purposes. </p><h3>Graphical abstract</h3>\u0000<div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":737,"journal":{"name":"Polymer Bulletin","volume":"82 7","pages":"2507 - 2522"},"PeriodicalIF":3.1,"publicationDate":"2024-12-27","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143818278","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}
