The study utilizes optical density measurements at 350 nm to track the sol-gel transition of different copolymer systems, including ELP 80, ELP (40)₂, C16-80-C16, and C16-(40)₂-C16, across a temperature range of 0-50°C. These thermograms reveal distinct transition temperatures for each copolymer, indicating their sensitivity to thermal changes. Dynamic light scattering analysis, presented as intensity versus hydrodynamic radius plots, further elucidates the aggregation behavior of C16-80-C16 and C16-(40)₂-C16 at varying temperatures, showing changes in particle size and distribution as temperature increases, which aligns with the observed phase transitions. The rheological properties of C16-80-C16 and C16-(40)₂-C16 are explored through oscillatory shear tests, measuring the storage modulus (G') and loss modulus (G'') as a function of angular frequency. These rheological data demonstrate the transition from a liquid-like to a solid-like state with increasing frequency and temperature, highlighting the formation of a viscoelastic network. The document provides visual representations of the hydrogel states for C16-80-C16 and C16-(40)₂-C16, offering a clear macroscopic view of their gelation. The chemical structures of the components, including C16 lipid chains and polypeptide segments, are illustrated, offering insights into how their amphiphilic nature and length influence the observed thermoresponsive phenomena. Overall, the study comprehensively characterizes the self-assembly and phase behavior of these block copolymers, providing valuable data for the design of smart materials.",{"@graph":63,"@context":118},[64,80,101],{"@type":65,"itemListElement":66},"BreadcrumbList",[67,71,74,77],{"item":68,"name":69,"@type":70,"position":9},"https://docshare.wps.com","Home","ListItem",{"item":72,"name":10,"@type":70,"position":73},"https://docshare.wps.com/template/",2,{"item":75,"name":51,"@type":70,"position":76},"https://docshare.wps.com/template/general/",3,{"item":78,"name":59,"@type":70,"position":79},"https://docshare.wps.com/template/the-thermoresponsive-behavior-of-amphiphilic-block-copolymers/189557/",4,{"url":78,"name":59,"@type":81,"image":82,"author":87,"headline":59,"publisher":90,"fileFormat":93,"inLanguage":57,"description":61,"dateModified":94,"datePublished":95,"encodingFormat":93,"isAccessibleForFree":96,"interactionStatistic":97},"DigitalDocument",{"url":83,"@type":84,"width":85,"height":86},"https://docshare.wps.com/thumbnails/the-thermoresponsive-behavior-of-amphiphilic-block-copolymers/189557.png","ImageObject",442,249,{"name":88,"@type":89},"Pentious","Person",{"url":68,"name":91,"@type":92},"DocShare","Organization","application/pdf","2026-09-30","2026-09-03",true,{"@type":98,"interactionType":99,"userInteractionCount":79},"InteractionCounter",{"@type":100},"ViewAction",{"@type":102,"mainEntity":103},"FAQPage",[104,110,114],{"name":105,"@type":106,"acceptedAnswer":107},"What method is used to measure the phase transitions of the block copolymers?","Question",{"text":108,"@type":109},"The phase transitions of the block copolymers are measured using optical density (OD) at 350 nm as a function of temperature.","Answer",{"name":111,"@type":106,"acceptedAnswer":112},"How does temperature affect the aggregation of C16-80-C16 and C16-(40)₂-C16?",{"text":113,"@type":109},"As temperature increases, these copolymers undergo self-assembly and aggregation, leading to changes in their hydrodynamic radius, indicating the formation of larger structures.",{"name":115,"@type":106,"acceptedAnswer":116},"What do the rheological measurements reveal about the C16-80-C16 and C16-(40)₂-C16 materials?",{"text":117,"@type":109},"Rheological measurements show that these materials form viscoelastic networks upon heating, transitioning from a liquid-like to a solid-like state with increasing frequency, as evidenced by the behavior of the storage and loss moduli.","https://schema.org",{"og:url":78,"og:type":120,"og:title":59,"og:site_name":91,"og:description":61},"article",{"robots":122,"canonical":78},"index,follow",{"doc_id":124,"site_id":56},189557,1790078277,{"code":4,"msg":5,"data":127},{"doc_id":124,"user_id":128,"nickname":88,"user_avatar":129,"doc_module":9,"category_id":50,"category_name":51,"doc_title":59,"doc_description":61,"doc_content":60,"file_id":130,"file_url":131,"file_type":132,"file_size":133,"view_count":79,"is_deleted":4,"is_public":9,"is_downloadable":9,"audit_status":9,"page_count":134,"language":135,"language_code":57,"site_id":56,"html_lang":57,"table_of_contents":136,"faqs":137,"seo_title":138,"seo_description":61,"update_tm":139,"read_time":20},1374404730887,"https://ap-avatar.wpscdn.com/davatar_6f874abed73319feea01a86fa6f0fab8","cbCaiczeLk3Wztpj","https://ap.wps.com/l/cbCaiczeLk3Wztpj","pdf",2621516,41,"English","# Optical Density Measurements\n## ELP 80\n## ELP (40)₂\n## C16-80-C16\n## C16-(40)₂-C16\n# Hydrodynamic Radius Analysis\n## C16-80-C16\n## C16-(40)₂-C16\n# Rheological Properties\n## C16-80-C16\n## C16-(40)₂-C16","[{\"question\":\"What method is used to measure the phase transitions of the block copolymers?\",\"answer\":\"The phase transitions of the block copolymers are measured using optical density (OD) at 350 nm as a function of temperature.\"},{\"question\":\"How does temperature affect the aggregation of C16-80-C16 and C16-(40)₂-C16?\",\"answer\":\"As temperature increases, these copolymers undergo self-assembly and aggregation, leading to changes in their hydrodynamic radius, indicating the formation of larger structures.\"},{\"question\":\"What do the rheological measurements reveal about the C16-80-C16 and C16-(40)₂-C16 materials?\",\"answer\":\"Rheological measurements show that these materials form viscoelastic networks upon heating, transitioning from a liquid-like to a solid-like state with increasing frequency, as evidenced by the behavior of the storage and loss moduli.\"}]","The Thermoresponsive Behavior of Amphiphilic Block Copolymers | PDF",1788397735]
