Nevertheless, the development of antibacterial hybrid material comprising both novolac type phenolic resin and AgNPs remains one of the untouched issues in human healthcare.We report herein the simple preparation of hybrid derived from functionalized novolac resin and AgNPs. The hybrid was tested for antibacterial activity towards Gram-positive and Gramnegative bacteria.Preparation and characterization of functionalized novolac resin and hybrid were achieved. Gram-positive bacteria (Staphylococcus aureus MTCC 3160, Staphylococcus epidermidis NCIM2493, Bacillus subtilis) and Gram-negative bacteria (Pseudomonas aeruginosa ATCC27853, Escherichia coli) were used to test the bactericidal efficiency of hybrid. The antibacterial effectiveness of hybrid was determined in terms of the minimum inhibitory concentration (MIC). In addition, treatment with hybrid caused cytoplasmic contents leakage evidencing membrane damage.The hybrid developed thus could provide opportunities to fabricate a wide range of antibacterial functional materials for different purposes in human health associated sectors.","PeriodicalId":10768,"journal":{"name":"Current Applied Polymer Science","volume":"22 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90600665","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From a chemical point of view, polyurethane foams are made from a chemical reaction between a polyol (molecules with more than one hydroxyl group) and a diisocyanate in the presence of a blowing agent.Because of their highly stable bonds, polyurethane foams are considered as nondegradable leading to some environmental impact. To address this concern different bio-based fillers have been used to create \"greener\" polyurethane materials. This review presents an overview of different bio-based fillers and containing natural polyols for polyurethane foams formulation with respect to their natural properties, sizes, geometries and contents.A wide range of bio-based fillers derived from wood and non-wood sources are summarized based on their physico-mechanical properties. Then, possible applications are presented and future trends are discussed for the research and development of these complex (multiphase systems) materials (polymer composite foams).Beside traditional polyurethane foams applications including automotive, building, home furniture and package, bio-based filler addition could bring new feature and widen their applications such as shape memory and medication, as well as oil absorbent.","PeriodicalId":10768,"journal":{"name":"Current Applied Polymer Science","volume":"44 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-03-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"90844829","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
