In 2007 the production of expanded polystyrene (EPS) in the world was over 4 million tonnes and is expected to grow at 6 percent per year. With the increased concern about environmental protection, alternative biodegradable materials from renewable resources are of interest. The present doctoral thesis work successfully demonstrates that starch-based foams with mechanical properties similar to EPS can be obtained by reinforcing the cell-walls in the foams with cellulose nanofibers (MFC).

Nanostructured biocomposites of high toughness—a wood cellulose nanofiber network in ductile hydroxyethylcellulose matrix

Nanopaper from wood-based nanofibrillated cellulose (NFC) offers vastly improved strength and strain-to-failure compared with plant fiber-based paper and plant fiber biocomposites. In the present

Cellulose nanocomposite biopolymer foam--hierarchical structure effects on energy absorption.

A starch-based biofoam is for the first time able to reach comparable mechanical properties to EPS at 50% relative humidity and similar relative density.

Mechanical performance tailoring of tough ultra-high porosity foams prepared from cellulose I nanofiber suspensions

Low-density structures of mechanical function in plants, arthropods and other organisms, are often based on high-strength cellulose or chitin nanofibers and show an interesting combination of

Multifunctional Bionanocomposite Foams with a Chitosan Matrix Reinforced by Nanofibrillated Cellulose

Multi-functional bionanocomposite foams with 3D interconnected networks showing advantageous mechanical property, thermal insulation, underwater oleophobicity, and biocompatibility, were made from

Cellulose Biocomposites—From Bulk Moldings to Nanostructured Systems

Cellulose biocomposites are widely used in industry as a low-cost engineering material with plant fiber reinforcement. However, chemical and microstructural heterogeneity causes low strength, low

The role of hemicellulose in nanofibrillated cellulose networks

It is found that removal of xylan enhances the formation of fibril networks, resulting in both stiffer gels and stronger films, however xylan also stabilizes the fibrils against flocculation.

Cellulose nanofibril (CNF) reinforced starch insulating foams

In this study, biodegradable foams were produced using cellulose nanofibrils (CNFs) and starch (S). The availability of high volumes of CNFs at lower costs is rapidly progressing with advances in

Biodegradable poly(vinyl alcohol) foams supported by cellulose nanofibrils: processing, structure, and properties.

Results show that the incorporation of CNF preferably at a weight ratio of 30 wt % greatly enhanced the mechanical strength and modulus, energy absorption, water resistance, and dimensional stability of the composite foams because of the rigid and semicrystalline nature of C NF.

Experimental characterisation of nanofibrillated cellulose foams

There is a growing interest in applications for nanofibrillated cellulose based materials owing to their exceptional mechanical properties. Nanofibrillated cellulose (NFC) foam is one such derivative



Plasticized Starch/Tunicin Whiskers Nanocomposite Materials. 2. Mechanical Behavior

In a previous work [Macromolecules 2000, 33, 8344], nanocomposite materials were obtained using glycerol plasticized starch as the matrix and a colloidal suspension of tunicinan animal

Enzymatic hydrolysis combined with mechanical shearing and high-pressure homogenization for nanoscale cellulose fibrils and strong gels.

Mild enzymatic hydrolysis has been introduced and combined with mechanical shearing and a high-pressure homogenization, leading to a controlled fibrillation down to nanoscale and a network of long and highly entangled cellulose I elements.

Cellulose microfibrils from potato tuber cells: Processing and characterization of starch–cellulose microfibril composites

The ultrastructure and morphology of potato (Solanum tuberosum L.) tuber cells were investigated by optical, scanning, and transmission electron microscopies. After removal of starch granules,

Novel thermoplastic starch–clay nanocomposite foams

Novel thermoplastic starch (TPS)–clay nanocomposite foams were prepared by melt-processing. The use of urea as plasticizer avoids the cracking of TPS during storage and enhances the dispersion of

The Effect of Starch Composition on Structure of Foams Prepared by Microwave Treatment

A microwave technique was used to prepare foams from different potato starches in granular form, with varying amounts of amylose content, and water. In addition to native potato starch (PN), high
