These polysaccharides, in equal weight ratio, were derivatized with succinic anhydride (SA) in the thermo-mechanical reactive extrusion process in the presence of different amounts of catalysts K2CO3 and\/or Zn(OAc)2. The reactions were performed at 130\u2013140 \u00b0C for 10 min. Sequentially, after removal of unreacted SA, the derivatized polysaccharides were neutralized with NaOH, KOH and\/or aq. NH3 to obtain superabsorbent materials. The esterified polysaccharides were crosslinked using glycidyl methacrylate (GMA) and\/or N,N\u2032-methylene bisacrylamide (MBA) and the effects were evaluated. The reactions were confirmed by attenuated total reflectance-Fourier transform Infra-red (ATR-FTIR) spectroscopic analysis and structural characterization was done by X-ray diffraction (XRD) and scanning electron microscopy (SEM). Among the catalysts, K2CO3 performed better than Zn(OAc)2, while among crosslinkers, MBA performed better than GMA crosslinker. The esterified polysaccharides showed optimum water absorption of 36.5 \u00b1 2.2 g\/g. Then the superabsorbent materials were used to grow maize plants, and the use of 0.4 wt.% functionalized SAPs in soil resulted in statistically significant increase in shoots length as compared to control, although no significant effect was observed on roots length.<\/jats:p>","DOI":"10.3390\/ijms27188097","type":"journal-article","created":{"date-parts":[[2026,9,11]],"date-time":"2026-09-11T13:29:29Z","timestamp":1789133369000},"page":"8097","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Mechanochemical Functionalization of Polysaccharides via Catalytic Esterification for the Preparation of Superabsorbent Materials for Plant Growth Applications"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-0550-6900","authenticated-orcid":false,"given":"Abdul","family":"Hafeez","sequence":"first","affiliation":[{"name":"Division of Biological Science and Technology, Graduate School of Natural Science and Technology, Kanazawa University, Kakuma-Machi, Kanazawa 920-1192, Ishikawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0009-0004-1498-0430","authenticated-orcid":false,"given":"Hao","family":"Wang","sequence":"additional","affiliation":[{"name":"Division of Biological Science and Technology, Graduate School of Natural Science and Technology, Kanazawa University, Kakuma-Machi, Kanazawa 920-1192, Ishikawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Romain","family":"Milotskyi","sequence":"additional","affiliation":[{"name":"Faculty of Biological Science and Technology, Institute of Science and Engineering, Kanazawa University, Kakuma-Machi, Kanazawa 920-1192, Ishikawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5835-1255","authenticated-orcid":false,"given":"Gyanendra","family":"Sharma","sequence":"additional","affiliation":[{"name":"Faculty of Biological Science and Technology, Institute of Science and Engineering, Kanazawa University, Kakuma-Machi, Kanazawa 920-1192, Ishikawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-2522-6711","authenticated-orcid":false,"given":"Naoki","family":"Wada","sequence":"additional","affiliation":[{"name":"Faculty of Biological Science and Technology, Institute of Science and Engineering, Kanazawa University, Kakuma-Machi, Kanazawa 920-1192, Ishikawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6775-9850","authenticated-orcid":false,"given":"Kenji","family":"Takahashi","sequence":"additional","affiliation":[{"name":"Faculty of Biological Science and Technology, Institute of Science and Engineering, Kanazawa University, Kakuma-Machi, Kanazawa 920-1192, Ishikawa, Japan"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2026,9,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"131204","DOI":"10.1016\/j.biortech.2024.131204","article-title":"Applications, Challenges and Prospects of Superabsorbent Polymers Based on Cellulose Derived from Lignocellulosic Biomass","volume":"408","author":"Dodangeh","year":"2024","journal-title":"Bioresour.
