Application of Polypyrrole Cellulose Nanocrystalline Composite Conductive Material in Garment Design

A Nanocellulose Polypyrrole Composite Based on Microfibrillated Cellulose from Wood

It is demonstrated that it is possible to coat the individual fibers of wood-based nanocellulose with polypyrrole using in situ chemical polymerization to obtain an electrically conducting continuous high-surface-area composite. The experimental results indicate that the high surface area of the water dispersed material, to a large extent, is maintained upon normal drying without the use of any...

Cellulose composite structures – by design

Optimum composite material design

— The microstructure identification problem is treated : given certain phases in given volume fractions, how to mix them in aperiodic cell so that the effective material constants of the periodic composite lie the closest possible to certain prescribed values ? The problem is studied for the linear conduction équation. It is stated in terms of optimal con trol theory ; the admissible micro geom...

Polypyrrole-incorporated conductive hyaluronic acid hydrogels

BACKGROUND Hydrogels that possess hydrophilic and soft characteristics have been widely used in various biomedical applications, such as tissue engineering scaffolds and drug delivery. Conventional hydrogels are not electrically conductive and thus their electrical communication with biological systems is limited. METHOD To create electrically conductive hydrogels, we fabricated composite hyd...

Nanocoating of natural cellulose fibers with conjugated polymer: hierarchical polypyrrole composite materials.

Astonishingly uniform polypyrrole nanocoating on morphologically complex cellulosic substances was achieved without disrupting the hierarchical network structures of individual cellulose fibers by means of polymerization-induced adsorption.
