Abstract
A microwave-generated plasma afterglow (MWGPA) treatment was applied to keratin fibers to improve their adhesion to anatase nanocrystals by modifying their surface chemical and physical structure.The induced photocatalytic self-cleaning property has significantly been improved by 70% as evidenced by complete stain decomposition in 6 h only.The effects of gas mixtures, gas flow, treatment distance, treatment duration and power flow of the MWGPA treatment on keratin's surface were investigated.The MWGPA-induced alteration of keratin's surface structure resulted in an increase in the uptake of anatase crystals and thus enhanced photocatalytic self-cleaning activities.The contact angle, absorption time, deposition behavior, adhesion and stability of anatase coating of keratin fibers are discussed.The anatase uptake and coating uniformity were characterized quantitatively using Time-of-Flight Secondary Ion Mass Spectrometry.This efficient and low energy plasma surface activation approach demonstrated potential toward the practical application of anatase in keratinous materials.© 2013 Elsevier B.V.All rights reserved.
