In this study, we used\u0000octavinyl-polyhedral oligomeric silsesquioxane OV-POSS to prevent all these problems and to enhance the dye\u0000properties. This is the first time to designe a novel near-IR absorption multifunctional materials over a wide PH (2-\u00009) with excellent properties of compatibility.

In this work, poly (N-(3-aminobenzyl)-N,N-dimethyl-N-dodecyl ammonium\u0000bromide) (PAS), a novel cathodic organic electrochemiluminescence (ECL) emitter, was synthesized by in-situ\u0000polymerization of the corresponding monomer on glass carbon electrode. The PAS ECL system was constructed with\u0000the PAS modified electrode, and potassium persulfate (KPS) as oxidizing agent and co-reactant. It was applied to the\u0000ECL detection of estradiol. According to the results of fluorescence and dynamic light scattering (DLS), mixed micelle\u0000of PAS and estradiol was formed. The combination of PAS with estradiol intensified the fluorescence of the ECL system\u0000and enlarged the colloidal size.

The roughness of the coatings was measured by profilometry and atomic force microscopy (AFM)\u0000and analyzed by a variety of statistical methods. Superhydrophobic surfaces showed a peak to peak distance below 5\u0000microns and a radius of less than 0.5 micron, but this information alone was insufficient to predict superhydrophobicity. The\u0000skewness and kurtosis for the surfaces indicated that all coated samples, both superhydrophobic and non-superhydrophobic,\u0000had a random Gaussian roughness distribution, but there was no significant difference in the skewness and kurtosis values\u0000for either superhydrophobic or non-superhydrophobic surfaces. The power spectral density function (PSDF) was found\u0000to be an effective tool to predict the required roughness for superhydrophobicity and provides information over the entire\u0000range of length scales.\u0000The average peak radius for the micro and nano scales calculated from ACL and RMS values were found to be less than\u00003 µm and 520 nm, respectively, which supports the accepted theory is that superhydrophobic surfaces require tightly\u0000packed asperities and small micron and nano roughness. The characterization of the surfaces allowed experimental\u0000verification of theoretical models for the roughness factor and critical roughness parameters. It was found that the\u0000RMS/ACL values should be 0.35 or higher for designing surfaces with contact angles above 150°. This work shows\u0000a unique method for measuring, quantifying, and understanding the role of roughness, that can be used to design\u0000surfaces for superhydrophobicity and future applications such as self-cleaning, icephobicity, anti-biofouling, corrosion\u0000resistance, and water repellency.","PeriodicalId":91888,"journal":{"name":"International journal of nanotechnology and nanomedicine","volume":"90 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-07-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84331976","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
