Fabrication of Thermoplastic Nanocellulose Composite Material

Lim D.-Y., Lee J.A., Kim K.-K., Korea Institute of Industrial Technology, KR

Nanocellulose fibers with the average diameter below 100nm were successfully obtained by a high shear microfluidizer as shown in Figure 1. Their large surface area and nano-scale dimensions can lead to the emerging materials for [...]

Sustainable and high-performable nano-structured biopackaging materials

Božič M., Majerič M., Kokol V., University of Maribor, SI

In the contribution, there will be presented few strategies that we have studied recently for producing of highly-performed rigid or flexible biopackaging materials, being fabricated as mono- or even multi-layers coating films from renewable biopolymers [...]

Degradability of polymeric composites (ENR/PLA) from renewable resources

Masek A., Zaborski M., Lodz University of Technology, PL

In our research, we reported on biodegradable composites exhibiting specificity properties by melt blending of polylactide (PLA), one of the commercially available biodegradable material, and epoxidized natural rubber (ENR). Blending of ENR with different types [...]

Natural polyphenols as pro-ecological antioxidants and pigments for polymer composites

Masek A., Zaborski M., Lodz University of Technology, PL

In our studies, we propose the use of natural, pro-ecological substances such as polyphenols to protect elastomers against ageing. This natural compounds were incorporated into ethylene-norbornene (COC-material is commercially available under the name of TOPAS); [...]

Extremely Flexible and Stretchable Carbon Nanotube Composites for Conformal Electronic Devices

Landorf C.W., Alford J., Garrison J., Gibbons S., Shih W-S, Leever B.J., Berrigan J.D., Brewer Science, Inc, US

Electronic devices are increasingly being used in products that are not expected to be rigid and flat. Many strategies have been implemented to create electronics that can work under stress and strain that would fracture [...]

Strain Tunable Resin and Coating Technology for Next Generation Composites

Lewit S.M., Structural Composites, Inc, US

Leveraging SBIR Technology for Advanced Combatant Craft has created an innovative new resin and coating technology Our patent pending Co-Cure technology allows for shop floor alteration of coating and resin properties. The invention relates to [...]

Ethylene Vinyl Acetate – Cloisite Nanocomposite Membranes and their Gas Separation Behavior

Ramadan A.R., Esawi A.M.K., Abdel-Hafiz A., Charmette C., Ayral A., The American University in Cairo, EG

The current work aims at understanding the correlation between EVA-montmorillonite clay nanocomposite membrane morphology and gas permeation properties. 5wt% of Cloisite-20A and 30B organoclays were added to EVA having 18wt% vinyl acetate. Nanocomposite membranes were [...]

Thermoelectric properties of nanocomposite Bi2Te3 layers prepared by PLD

Zeipl R., Jelinek M., Vlčekb M., Kocourek T., Vanišc J., Institute of Physics ASCR, CZ

We present some thermoelectric properties of Bi2Te3 nano-layers of different thickness prepared by Pulsed Laser Deposition such as the thermal conductivity, in-plain electrical conductivity and the Seebeck coefficient. Layers are prepared under various deposition conditions. [...]

Inducing Polymer Interphase Formation in the Composite at Low Nano-Carbon Loading

Song K., Minus M.L., Northeastern University, US

The nano-carbons used in this work are layered carbon nano-chips that exhibit platelet morphology and are able to slide with respect to each other. Both filled and unfilled poly(vinyl alcohol) (PVA) fibers were studied to [...]
