Abstract

Continuous metalized regenerated cellulose fibers for advanced applications (e.g., multi-functional composites) are produced by electroless copper plating. Copper is successfully deposited on the surface of cellulose fibers using commercial cyanide-free electroless copper plating packages commonly available for the manufacturing of printed wiring boards. The deposited copper was found to enhance the thermal stability, electrical conductivity and resistance to moisture uptake of the fibers. On the other hand, the chemistry involved in plating altered the molecular structure of the fibers, as was indicated by the degradation of their mechanical performance (tensile strength and modulus).

Highlights

Regenerated cellulose fibers (RCFs) are man-made fibers from naturally occurring cellulose that is spun-formed into continuous, uniform cross-sectional fibers with rather stable physical properties [1].When compared with natural plant fibers, the properties of RCFs are more application-tunable and less dependent on the cellulose source or the growing–cultivation conditions
Bundles of regenerated cellulose fibers (Cordenka 700 Super 3 from Cordenka GmbH, Obernburg, Germany) of 50 mm length were used in this study
The chemicals used for the electroless plating were commercially available solutions from JKEM international, Sweden

Summary

Introduction

When compared with natural plant fibers, the properties of RCFs are more application-tunable and less dependent on the cellulose source or the growing–cultivation conditions. Considering their natural origin and end-of-life disposal, the latest generations of these fibers are more environmentally friendly than the conventional fibers [2,3] used in composites (e.g., glass, carbon) or in textiles (e.g., polyester, polyamide). RCFs are commercially available and are used in various applications with increasing interest in the research and development sectors to improve their performance for use in composites as a reinforcement [4] In order for these materials to be used in advanced applications, does their mechanical performance need to be improved, but the addition of new functionalities has become essential. This can boost their potential limits and suitability for a wider range of applications
