Elaboration and Characterization of Nano-Biocomposites Based on Plasticized Poly(Hydroxybutyrate-Co-Hydroxyvalerate) with Organo-Modified Montmorillonite
(SPRINGER/PLENUM PUBLISHERSNEW YORK, 2012)
Nano-biocomposites based on a biodegradable bacterial copolyester, poly(hydroxybutyrate-co-hydroxyvalerate), have been elaborated with an organo-modified montmorillonite (OMMT) clay as nanofiller, and acetyl tributyl citrate ...
Processing and characterization of 100% hemp-based biocomposites obtained by vacuum infusion
(Sage Publications Ltd, 2013-05-03)
Novel biocomposites made of an acrylated epoxidized hemp oil based bioresin reinforced with random hemp fiber mat were manufactured by the vacuum infusion technique. Mechanical properties (tensile, flexural, Charpy impact ...
Wide range humidity sensors printed on biocomposite films of cellulose nanofibril and poly(ethylene glycol)
(John Wiley & Sons Inc, 2019-09)
Cellulose nanofibril (CNF) films were prepared from side streams generated by the sugarcane industry, that is, bagasse. Two fractionation processes were utilized for comparison purposes: (1) soda and (2) hot water and soda ...
Life cycle assessment of bagasse fiber reinforced biocomposites
(Elsevier, 2020-06)
This study aims to evaluate the life cycle environmental implications of producing fiber-reinforced biocomposite pellets, compared with sugarcane- and petroleum-based polyethylene (PE) pellets. Life Cycle Assessment (LCA) ...

Aims: To assess the antibacterial efficacy of new composite materials developed from microparticles of 45S5 bioactive glass (BG) and agar-gelatin films. Methods and Results: In vitro antibacterial activity was evaluated ...
Particle Size Distribution Effect on Cassava Starch and Cassava Bagasse Biocomposites
(American Chemical Society, 2019-01)
Regarding the growing interest in the development of biodegradable films from renewable sources, this work is focused on the utilization of cassava roots bagasse as a natural filler of cassava starch films. Homogenous films ...
Optimized and scaled-up production of cellulose-reinforced biodegradable composite films made up of carrot processing waste
(Elsevier B.V., 2018-10-01)
The ever-growing environmental concern arising from the unrestricted exploitation of fossil sources for the massive production of non-biodegradable materials encourages research on alternative renewable resources. We herein ...
The mechanical properties of flax fibre reinforced poly(lactic acid) bio-composites exposed to wet, freezing and humid environments
(Sage Publications Ltd, 2017-06-20)
Bio-composites are increasingly being perceived as a green alternative to synthetic composites in many applications. However, the overall long-term durability of bio-composites is a major concern, particularly their ability ...
