3.1 Prehydrolysis liquors valorized to a flame-retardant coating
The production of dissolving grade pulp necessitates the removal of hemicellulose from biomass. The resulting prehydrolysis liquors are currently incinerated at low efficiency, hampering pulp production. Herein, the preparation and characterization of a polymer synthesized from hemicellulose derived monomers is described, offering an alternative to incineration. The polymer was prepared without solvent at room temperature, […]
3.Keynote – Sustainable polyesters and resin components: combining bio-based resources with function integration
The incorporation of biobased monomers into polymer structures offers the possibility to develop materials in a more climate-friendly way. By using biogenic monomers, the carbon footprint of polymer production can be reduced. In the recent years we have developed thermoplastic and duroplastic polymer materials with specific biobased units for integrating specific functions. An example will […]
3.Invited – Synthetic carbohydrate polymers from xylose and other natural sugars: design, polymerisation and applications
In the context of the defossilisation of the chemical industry, our team has been investigating the incorporation of monosaccharides into synthetic polymer backbones. The goal of this research is to create renewable materials with attractive sustainability attributes (e.g., degradability, chemical recyclability), and which are tuneable thanks to the functionalisation potential of sugar moieties. This talk will […]
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 […]
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 […]
3.3 Development of biobased terpenoid-acrylic copolymers incorporating lignin-based UV blockers for wood protection
One of the main resources for renewable materials has been wood waste. In this sense, terpenes, which are extracted from coniferous trees as well as citrus fruits, are an exploitable category of biomass.The objective of this study is to develop innovative wood coatings using renewable bio-based polyacrylates from terpenoids, a subclass of terpenes used on […]
3.4 Suberin-based aqueous dispersions for barrier packaging applications
Barriers and coatings are commonly used as protective layers of consumables such as food and liquid packages1,2, however, currently harnessed conventional barrier layers are predominantly made from fossil-based polymers, with increasing global consumption causing concerns related to climate change. Therefore, bio-based barriers and coatings are urgently needed to reduce greenhouse gas emissions and our dependency […]
3.5 Sustainable UV-Cured polymers from ligning-derived biomass precursors
Industrial pulp and paper process represent a large market that can allow the use of by-product to avoid waste production and reduce pollution. Lignin represents the most available side product that can be used to produce bio-based monomer [1].In this study different ligning-derived biobased monomers have been synthesized and exploited both in cationic and radical […]
P3.1 – Hydrogen bond donor additive in cellulose ester films for thermally expandable microspheres
Cellulose based materials have a range of material properties, that can be tweaked even further by the addition of additives to suit specific applications. With the goal to make thermally expandable microspheres (TEMS) of cellulose based materials, the additive is a vital component, that broadens the barrier- and softening properties. TEMS are developed under the […]
P3.2 – Synthesis of functionalized conjugated polymers for creating cellulose/CP hybrid materials
Synthesis of functionalized conjugated polymers for creating cellulose/CP hybrid materialsAsaminew Yerango (asaminew.yerango.shimolo@liu.se), Bernhard Burtscher (bernhard.burtscher@liu.se), Xenofon Strakosas (xenofon.strakosas@liu.se), Renee Kroon (renee.kroon@liu.se) Abstract Blending conjugated polymers (CPs) with cellulose is a promising approach to enhance their properties and create composite materials with properties that are greater than the sum of their separate components. To combine these […]
