Abstract

Priprava funkcionalne odzivne tkanine iz poliamida 6 z mikrogelom z vključenim ZnO

Highlights

Stimuli-responsive microgels are water-insoluble three–dimensional cross-linked polymers that can absorb and desorb large quantities of water, changing their volume by swelling or de-swelling [1,2,3]
A new functional, stimuli-responsive microgel coating on polyamide 6 (PA6) fabric with simultaneous temperature (T)- and pH-responsive moisture management, UV protection and photocatalytic self-cleaning properties was prepared by applying poly-(N-isopropylacrylamide)/chitosan (PNCS) microgel in combination with ZnO nanoparticles to PA6 fabric
Bright spots which are clearly visible on the PA(ZnO) sample are attributed to the ZnO particles, which confirm that smaller to larger agglomerates of ZnO nanoparticles were formed on the fibres

Summary

Introduction

Stimuli-responsive microgels are water-insoluble three–dimensional cross-linked polymers that can absorb and desorb large quantities of water, changing their volume by swelling or de-swelling [1,2,3]. The concept of the present research was to create new functional properties that will complement the thermoregulation and moisture management for comfort improvement of textiles by preparing the PNCS microgel with UV protection and self-cleaning properties. To this end, ZnO was chosen as a very promising candidate that could provide these properties and contribute to the added value of the PNCS microgel coating. ZnO nanoparticles (NPs) were incorporated into PNCS microgel and applied to polyamide 6 (PA6) fabric with the aim to create pH- and temperature-responsive fabric with UVprotective and self-cleaning properties. Based on the determination of stimuli responsive, UV protective and self-cleaning properties of the coated fabric, the most effective functionalization procedure was chosen
