One possible approach is to increase the performance of adhesives such as polyvinyl acetate (PVAc) or melamine-urea-formaldehyde (MUF) by means of nanoparticles in order to obtain a material with better mechanical and environmental resistance. When applying cellulose-based nanoparticles or tannin, the concept of a circular economy is successfully implemented into the forest\/wood value chain, and chances are created to develop new value chains using byproducts of forestry operations. In this study, assortments coming from young sweet chestnut (Castanea sativa Mill.) coppice stands were utilized for the preparation of single lap joint assemblies using different commercial adhesives (PVAc, MUF) and cellulose nanocrystals (CNC) and tannin as additives. The results showed that addition of CNC and tannin to PVAc glue increased tensile shear strength in lap joint tests presenting a promising base for future tests regarding the addition of CNC and tannin in MUF or PVAc adhesive formulations. Unfortunately, the tested bio-based additives did not reveal the same encouraging results when tested in the wet state.<\/jats:p>","DOI":"10.3390\/nano10050956","type":"journal-article","created":{"date-parts":[[2020,5,18]],"date-time":"2020-05-18T11:34:14Z","timestamp":1589801654000},"page":"956","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":22,"title":["Impact of Bio-Based (Tannins) and Nano-Scale (CNC) Additives on Bonding Properties of Synthetic Adhesives (PVAc and MUF) Using Chestnut Wood from Young Coppice Stands"],"prefix":"10.3390","volume":"10","author":[{"given":"Francesco","family":"Marini","sequence":"first","affiliation":[{"name":"Department of Innovation for Biological, Agrifood and Forest System (DIBAF), University of Tuscia, 01100 Viterbo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7842-2655","authenticated-orcid":false,"given":"Florian","family":"Zikeli","sequence":"additional","affiliation":[{"name":"Centro Studi Alpino (CSALP) of the University of Tuscia, 38050 Pieve Tesino, Italy"},{"name":"Institute of Chemical, Environmental and Bioscience Engineering, TU Wien, 1060 Vienna, Austria"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-8105-0792","authenticated-orcid":false,"given":"Piermaria","family":"Corona","sequence":"additional","affiliation":[{"name":"CREA (Council for Agricultural Research and Economics) Research Centre for Forestry and Wood, 52100 Arezzo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vittorio","family":"Vinciguerra","sequence":"additional","affiliation":[{"name":"Department of Innovation for Biological, Agrifood and Forest System (DIBAF), University of Tuscia, 01100 Viterbo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-9755-4605","authenticated-orcid":false,"given":"Maria Chiara","family":"Manetti","sequence":"additional","affiliation":[{"name":"CREA (Council for Agricultural Research and Economics) Research Centre for Forestry and Wood, 52100 Arezzo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Luigi","family":"Portoghesi","sequence":"additional","affiliation":[{"name":"Department of Innovation for Biological, Agrifood and Forest System (DIBAF), University of Tuscia, 01100 Viterbo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Giuseppe","family":"Scarascia Mugnozza","sequence":"additional","affiliation":[{"name":"Department of Innovation for Biological, Agrifood and Forest System (DIBAF), University of Tuscia, 01100 Viterbo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-2568-6411","authenticated-orcid":false,"given":"Manuela","family":"Romagnoli","sequence":"additional","affiliation":[{"name":"Department of Innovation for Biological, Agrifood and Forest System (DIBAF), University of Tuscia, 01100 Viterbo, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2020,5,18]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Romagnoli, M., Fragiacomo, M., Brunori, A., Follesa, M., and Mugnozza, G.S.
