However, abundant lattice defects severely degrade its conductivity. Herein, from an innovative perspective of precursor design, the poly-phenylamines (P-PAs) with improved solubility and strong light absorption were synthesized, which act as an intercalated polymer for graphene oxide (GO) nanosheets. On this basis, the composite precursors show remarkably enhanced photothermal conversion capability and a compact stacked structure. These bring a 60% reduction in ID\/IG in LIG after laser irradiation. To explain the above phenomenon, an isolation effect induced by the compact stacking precursor is proposed based on experimental results. Furthermore, the cooperative effect between P-PAs and Fe2+ is introduced, and a fluffy LIG aerogel with the lowest ID\/IG ratio of 0.17 is prepared, which is barely achievable in conventional LIGs. When the obtained graphene aerogel is compounded with PDMS, the as-prepared thermal-conductive composite gel reaches a thermal conductivity of 1.05 W\u00b7m\u22121\u00b7K\u22121 and an ultralow interfacial thermal resistance of 37.2 mm2\u00b7K\u00b7W\u22121 under a low graphene loading of 3.3 wt%. This intercalation strategy in GO precursor supplies a new route for preparing high-quality LIGs and thermal-conductive gels, which show great application prospects in thermal management devices.<\/jats:p>","DOI":"10.3390\/gels12090835","type":"journal-article","created":{"date-parts":[[2026,9,11]],"date-time":"2026-09-11T17:14:59Z","timestamp":1789146899000},"page":"835","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Cooperative Repair for Laser-Induced Graphene via Modified Poly-phenylamine and Fe2+ for Thermal-Conductive Gels"],"prefix":"10.3390","volume":"12","author":[{"given":"Nan","family":"Jiang","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering, Wuhan University of Technology, No.122, Luoyu Road, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"data-curation","vocabulary":"credit"},{"role":"writing-original-draft","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"given":"Guomin","family":"Ding","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Wuhan University of Technology, No.122, Luoyu Road, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"methodology","vocabulary":"credit"},{"role":"supervision","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"given":"Bowen","family":"Yang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Wuhan University of Technology, No.122, Luoyu Road, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"methodology","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"given":"Shuai","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Wuhan University of Technology, No.122, Luoyu Road, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"given":"Luyao","family":"Wang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Wuhan University of Technology, No.122, Luoyu Road, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"conceptualization","vocabulary":"credit"},{"role":"investigation","vocabulary":"credit"},{"role":"resources","vocabulary":"credit"}]},{"given":"Zihan","family":"Li","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Wuhan University of Technology, No.122, Luoyu Road, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"data-curation","vocabulary":"credit"},{"role":"visualization","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"given":"Xu","family":"Han","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Wuhan University of Technology, No.122, Luoyu Road, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"resources","vocabulary":"credit"},{"role":"validation","vocabulary":"credit"},{"role":"writing-review-editing","vocabulary":"credit"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7343-9637","authenticated-orcid":false,"given":"Qilin","family":"Mei","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, Wuhan University of Technology, No.122, Luoyu Road, Wuhan 430070, China"}],"role":[{"vocabulary":"crossref","role":"author"},{"role":"investigation","vocabulary":"credit"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"572","DOI":"10.1038\/s41586-024-08003-w","article-title":"Robust Chemical Analysis with Graphene Chemosensors and Machine Learning","volume":"634","author":"Pannone","year":"2024","journal-title":"Nature"},{"key":"ref_2","doi-asserted-by":"crossref","first-page":"792","DOI":"10.1038\/s41467-024-55790-x","article-title":"Thermoelectric Porous Laser-Induced Graphene-Based Strain-Temperature Decoupling and Self-Powered Sensing","volume":"16","author":"Yang","year":"2025","journal-title":"Nat.
