In this work we examine how the inherent macromolecular properties of keratin and lignin can be utilised and developed using green chemistry principles to form 4D functional materials. A new methodology utilising protein complexation by lignin was applied to form copolymers and reinforce keratin cross-linking networks on aqueous and solid state processing. Solubility, chemical and processing characteristics found a favoured 4:1 ratio of keratin to lignin was most desired for effective further processing as 3D printed forms. Thermally processing keratin-lignin with plasticisers and processing aids demonstrated extruded FDM filaments could be formed at temperatures >130˚C, but degradation of keratin-lignin materials was observed. Employing paste printing strategies, keratin-lignin hydrogels could successfully print 3D skirt outlines. This was achieved with aqueous hydrogels prepared at 30-40% solids content with and without plasticizers over a defined processing timeframe. Mechanical response to moisture stimuli was successfully demonstrated for the 4:1 keratin-lignin printed material on water soaking, realising the ability of these keratin-lignin biocomposite materials to introduce a 4th dimensional response after 3D printing.","PeriodicalId":11894,"journal":{"name":"EngRN: Biomaterials (Topic)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87784353","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}

The development and testing in human physiological equivalent fluids of new hybrid biomaterials are presented. The role of water and its equilibrium modification in the human physiology is discussed and the swelling and sorption behavior in the physiological environment of a nanostructured and osteoconductive biomaterials based on Poly-Hydroxyl-Ethyl-Meth Acrylate matrix (pHEMA) filled with fumed amorphous nanosilica particles is presented. This material differently swells in presence of aqueous physiological solution fluid. Biological hybrid scaffolds for bone regeneration and growth made using synthetic materials able to correctly interact with the physiological fluids while inducing the growth of biological tissues may favor the birth in the medical field of a new class of hybrid materials. Our multidisciplinary approach explores in the this paper, novel ideas in modeling, design and fabrication of new nanostructured scaffolding biomaterials with enhanced functionality and improved interaction with OB cells.","PeriodicalId":11894,"journal":{"name":"EngRN: Biomaterials (Topic)","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2016-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"77791429","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}
