3.2 Enzymatic grafting of ferulic acid to cellulose fibers for the production of bioactive functional foams
With more and more prominence on the green transition, it is becoming increasingly important to find holistic resource efficient processes to replace traditional fossil-based systems. One such industry is the polymer foam industry which today relies heavily on polystyrene, polyurethane, polyethylene etc. which are synthesized from petroleum. Naturally, these foams are non-biodegradable and derived from […]
3.6 Betulin epoxide polymer for coatings
The growing demand for sustainable alternatives to petrochemical-based epoxy resins has led to the development of bio-based systems. This study introduces a new synthesis method using betulin from birch bark to produce high-value polymeric resins. A novel betulin-derived epoxide (BOE) was synthesized and combined with epoxidized rapeseed oil (ERO), then thermally cured with seven anhydrides […]
1.2 Tropical lignocellulosic biomass valorisation towards sustainable materials
Coconut agriculture is considered an economical crop that is commonly cultivated in the tropics. Annually, approximately 300 million tonnes of coconut were produced globally. The coconut husk constitutes about 40% of the entire fruit and is generally incinerated or brought to landfills, which could further emit unwanted greenhouse gases. The main composition of CH comprises […]
10.4 Scattering Studies of Wood-Based, Hybrid Materials and their Constituents
The macroscopic properties, e.g. mechanical, of wood-based materials depends on their molecular and nanoscale structure. For example, the deformation of wood cells can be directly related to their hierarchical architecture and to a stick–slip mechanism at the molecular and nanometer scale [1]. Observing the length scales up to micrometer is necessary to understand the wood-based […]
11.5 Printed circuit board substrates derived from lignocellulose nanofibrils
The growing problem of electronic waste poses an environmental challenge due to petroleum-based materials and toxic metals. Recycling e-waste is complex and costly due to numerous components requiring separation. Using bio-based, biodegradable materials for printed circuit board (PCB) substrates simplifies PCB component separation and improves environmental impact [1]. Hornified cellulose fibrils are promising PCB substrates […]
5.2 Nacre-inspired Composite Films Based on Cellulose Nanofibrils
The cellulose is the most abundant natural based polymer materials, has the advantages of renewable and biodegradable. The extraction process of cellulose into nanocellulose via up-bottom design strategy could afford high-performance to the materials. Cellulose nanofibrils (CNFs) are flexible, high-strength fibrils disintegrated from chemical wood pulp fibers, with typical diameters in the 3-10 nm range […]
4.3 Hierarchical wood structures for smart and functional materials
Wood is a hierarchically structural material with highly porous characteristics. However, it has not targeted on structural design in precise nanostructured control of the wood cell wall, which could extend the multiple functionalities range. Recently, emerging nanotechnologies have been explored the great potentials of wood to smart and functional materials. Wood nanotechnologies and cell wall […]
11.4 Printed electronics directly on wood veneers
Sustainability is becoming an increasingly crucial focus across various industries, reigniting interest in wood as a material. The major objective of this project is to pave the way for the transition of wood from a conventionally utilized resource to a highly functional and, at the same time, aesthetic material. From this transformation, wood will emerge […]
6.2 Production of M-NFC from poplar wood chips: impact of a mechano-enzymatic pre-treatment on M-NFC fiber quality
NFC production is a well-known process that is more and more used to produce high added-value products for many applications such as food packaging, rheology agents or composites. However, production requires a lot of energy such as electricity or water. Starting from industrial poplar wood chips, we propose to combine an enzymatic treatment with a […]
13.5 Green Polymer Synthetic Methodology Development towards Sustainable and Biobased Circular Materials
Green material solutions are instrumental in our collective pursuit of a more sustainable society. The bio-based origin is central; however, if this does not connect to circularity and benign synthesis, we will face the same plastic waste problem as today. My research team is highly interdisciplinary, covering polymer, organic, and biopolymer chemistry, with a focus […]
