In this work, carboxymethyl cellulose coated core\/shell SiO2@Cu nanoparticles (NPs) were synthesized by a simple and effective chemical reduction process. The initial SiO2 NPs, which were prepared from rice husk ash, were coated by a copper ultrathin film using hydrazine and carboxymethyl cellulose (CMC) as reducing agent and stable agent, respectively. The core\/shell SiO2@Cu nanoparticles with an average size of ~19 nm were surrounded by CMC. The results indicated that the SiO2@Cu@CMC suspension was a homogenous morphology with a spherical shape, regular dispersion and good stability. Furthermore, the multicomponent SiO2@Cu@CMC NPs showed good antifungal activity against Phytophthora capsici (P. capsici). The novel Cu NPs-based multicomponent suspension is a key compound in the development of new fungicides for the control of the Phytophthora disease.<\/jats:p>","DOI":"10.3390\/polym13060888","type":"journal-article","created":{"date-parts":[[2021,3,14]],"date-time":"2021-03-14T23:52:06Z","timestamp":1615765926000},"page":"888","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":12,"title":["Facile Synthesis of Carboxymethyl Cellulose Coated Core\/Shell SiO2@Cu Nanoparticles and Their Antifungal Activity against Phytophthora capsici"],"prefix":"10.3390","volume":"13","author":[{"given":"Nguyen Thi Thanh","family":"Hai","sequence":"first","affiliation":[{"name":"Department of Chemistry, University of Sciences, Hue University, 77 Nguyen Hue Street, Hue City 530000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7341-3661","authenticated-orcid":false,"given":"Nguyen Duc","family":"Cuong","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Sciences, Hue University, 77 Nguyen Hue Street, Hue City 530000, Vietnam"},{"name":"School of Hospitality and Tourism, Hue University, 22 Lam Hoang Street, Hue City 530000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nguyen Tran","family":"Quyen","sequence":"additional","affiliation":[{"name":"Pepper Research and Development Center, Pleiku City 600000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nguyen Quoc","family":"Hien","sequence":"additional","affiliation":[{"name":"Research and Development Center for Radiation Technology, Viet Nam Atomic Energy Institute, Ho Chi Minh City 700000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Tran Thi Dieu","family":"Hien","sequence":"additional","affiliation":[{"name":"Pepper Research and Development Center, Pleiku City 600000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Nguyen Thi Thanh","family":"Phung","sequence":"additional","affiliation":[{"name":"Pepper Research and Development Center, Pleiku City 600000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dao Khac","family":"Toan","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Sciences, Hue University, 77 Nguyen Hue Street, Hue City 530000, Vietnam"},{"name":"Nguyen Binh Khiem High School, Chu Se District, Pleiku City 600000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8112-5870","authenticated-orcid":false,"given":"Nguyen Thi Thu","family":"Huong","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Sciences, Hue University, 77 Nguyen Hue Street, Hue City 530000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dang Van","family":"Phu","sequence":"additional","affiliation":[{"name":"Research and Development Center for Radiation Technology, Viet Nam Atomic Energy Institute, Ho Chi Minh City 700000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4316-4860","authenticated-orcid":false,"given":"Tran Thai","family":"Hoa","sequence":"additional","affiliation":[{"name":"Department of Chemistry, University of Sciences, Hue University, 77 Nguyen Hue Street, Hue City 530000, Vietnam"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2021,3,14]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Brauer, V.S., Rezende, C.P., Pessoni, A.M., De Paula, R.G., Rangappa, K.S., Nayaka, S.C., Gupta, V.K., and Almeida, F.
