At present, thermal annealing is generally used to improve the mechanical properties of 3D\u2010PEEK. However, it cannot simultaneously improve strength and ductility. Here, a cost\u2010effective postprocessing method is developed to improve the mechanical properties of 3D\u2010PEEK, based on annealing in nonsolvent vapor at room temperature. The annealing in nonsolvent vapor at room temperature simultaneously improves the strength, ductility, and fracture energy of as\u2010printed 3D\u2010PEEK by 22.6%, 151.3%, and 109.1%, respectively. The improved mechanical properties are attributed to enhanced interfacial bonding, increased crystallinity, decreased pinhole defects, and stress relaxation in the 3D\u2010PEEK. Moreover, the annealing in both polar solvents (such as acetone and chloroform) and nonpolar solvents (such as n\u2010hexane) are demonstrated to be effective for improving the mechanical properties of 3D\u2010PEEK. The nonsolvent vapor\u2010annealed 3D\u2010PEEK can thus have potential applications in the fields of medical implants, automotive, aerospace, and more.<\/jats:p>","DOI":"10.1002\/marc.202100874","type":"journal-article","created":{"date-parts":[[2022,2,9]],"date-time":"2022-02-09T13:49:13Z","timestamp":1644414553000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":32,"title":["Improvement in Mechanical Properties of 3D\u2010Printed PEEK Structure by Nonsolvent Vapor Annealing"],"prefix":"10.1002","volume":"43","author":[{"given":"Wenhui","family":"Chen","sequence":"first","affiliation":[{"name":"School of Power and Mechanical Engineering and Institute of Technological Science Wuhan University  8 South Donghu Road Wuhan 430072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaolong","family":"Zhang","sequence":"additional","affiliation":[{"name":"School of Power and Mechanical Engineering and Institute of Technological Science Wuhan University  8 South Donghu Road Wuhan 430072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Di","family":"Tan","sequence":"additional","affiliation":[{"name":"School of Power and Mechanical Engineering and Institute of Technological Science Wuhan University  8 South Donghu Road Wuhan 430072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peng","family":"Xu","sequence":"additional","affiliation":[{"name":"School of Power and Mechanical Engineering and Institute of Technological Science Wuhan University  8 South Donghu Road Wuhan 430072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Baisong","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Power and Mechanical Engineering and Institute of Technological Science Wuhan University  8 South Donghu Road Wuhan 430072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kui","family":"Shi","sequence":"additional","affiliation":[{"name":"School of Power and Mechanical Engineering and Institute of Technological Science Wuhan University  8 South Donghu Road Wuhan 430072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo","family":"Zhu","sequence":"additional","affiliation":[{"name":"School of Power and Mechanical Engineering and Institute of Technological Science Wuhan University  8 South Donghu Road Wuhan 430072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Quan","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Power and Mechanical Engineering and Institute of Technological Science Wuhan University  8 South Donghu Road Wuhan 430072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yifeng","family":"Lei","sequence":"additional","affiliation":[{"name":"School of Power and Mechanical Engineering and Institute of Technological Science Wuhan University  8 South Donghu Road Wuhan 430072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sheng","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Power and Mechanical Engineering and Institute of Technological Science Wuhan University  8 South Donghu Road Wuhan 430072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5512-747X","authenticated-orcid":false,"given":"Longjian","family":"Xue","sequence":"additional","affiliation":[{"name":"School of Power and Mechanical Engineering and Institute of Technological Science Wuhan University  8 South Donghu Road Wuhan 430072 China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2022,2,19]]},"reference":[{"key":"e_1_2_8_1_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.compositesb.2018.02.012"},{"key":"e_1_2_8_2_1","doi-asserted-by":"publisher","DOI":"10.1038\/nbt.2958"},{"key":"e_1_2_8_3_1","doi-asserted-by":"publisher","DOI":"10.1007\/s11434-016-1191-y"},{"key":"e_1_2_8_4_1","doi-asserted-by":"publisher","DOI":"10.1007\/s10853-019-04259-0"},{"key":"e_1_2_8_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.actbio.2014.05.015"},{"key":"e_1_2_8_6_1","doi-asserted-by":"publisher","DOI":"10.1080\/17452759.2016.1265992"},{"key":"e_1_2_8_7_1","doi-asserted-by":"publisher","DOI":"10.1002\/app.29765"},{"key":"e_1_2_8_8_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.biomaterials.2007.07.013"},{"key":"e_1_2_8_9_1","doi-asserted-by":"publisher","DOI":"10.1038\/s41586-018-0474-7"},{"key":"e_1_2_8_10_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.compositesa.2016.05.032"},{"key":"e_1_2_8_11_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.compositesa.2019.03.020"},{"key":"e_1_2_8_12_1","first-page":"576","author":"Conrad T.
