Tannin from Schinopsis balansae applied to the nanofunctionalization of protective antifungal coatings

Fungal physical, chemical and aesthetical deterioration can occur by microbial biofilms adhere to the surface, leading alterations on paints integrity. The sol–gel method affords various merits added with biocides be used control paint films biodeterioration. aim of present research was obtain an efficient antifungal protection waterborne using a coating silver nanoparticles synthesized green methodology Schinopsis balansae tannin aqueous solution. Herein, low cost eco-friendly for preparation nanoparticles. activity assessed against Aspergillus niger MN371276, Penicillium commune MN371392, Cladosporium sphaerospermum MN371394 Lasiodiplodia theobromae MN371283. In addition, nanofunctionalized coatings were characterized SEM micrographs, EDS spectroscopy mapping, contact angle determination absorption/ desorption cycles humidity. resistance test over showed prevent fungal biofilm development 100% inhibition all strains tested. • Nanoparticles from are alternative. obtained easily quickly applied treatment. results in acrylic deterioration.
