Abstract:	摘要： The effect of surface condition on the photoalignment of light-induced methyl red (MR) adsorption phenomena on various substrates based on azo dye-doped liquid crystals is investigated. The results show that the polar surface energy determines the initiation of MR adsorption phenomena. The surface polarity energy of different substrates, which are modulated by oxygen plasma treatment (OPT), is further examined using the sessile drop method. The results also indicate that the uniformity and efficiency of MR adsorption can be enhanced by OPT. Light intensity influences the MR adsorption rate. The uniformity of MR adsorption onto various substrates is analysed via polarised optical microscopy. 出版者： Abingdon: Taylor & Francis 出版日期： 2016-07-14 出處： Liquid crystals, 2016-07, Vol.43 (9), p.1221-1229 版權： 2016 Informa UK Limited, trading as Taylor & Francis Group 2016 版權： 2016 Informa UK Limited, trading as Taylor & Francis Group 識別號： ISSN: 0267-8292 識別號： EISSN: 1366-5855 識別號： DOI: 10.1080/02678292.2016.1163740
