A secondary purpose is to maintain the aesthetic aspects and value of expensive good such as cars, trucks and aeroplanes. The cost of corrosion runs to approximately 3-4 % of GDP on an annual basis and therefore has an global economic impact of around US$3.3 billion.

Analysis of an unsteady quasi-capillary channel flow with time-resolved PIV and RBF-based super-resolution in JOURNAL OF COATINGS TECHNOLOGY AND RESEARCH, Vol. 20, N° 1 (01/2023)

The configuration consists of a liquid column that moves along a vertical 2D channel, open to the atmosphere and driven by a controlled pressure head. Both advancing and receding contact lines were analyzed to test the validity of classic models for dynamic wetting and to study the flow field near the interface. The operating conditions are characterized by a large acceleration, thus dominated by inertia. The shape of the moving meniscus was retrieved using Laser-Induced Fluorescence-based image processing, while the flow field near was analyzed via Time-Resolved Particle Image Velocimetry (TR-PIV). The TR-PIV measurements were enhanced in the post-processing, using a combination of Proper Orthogonal Decomposition and Radial Basis Functions to achieve super-resolution of the velocity field. Large counter-rotating vortices were observed, and their evolution was monitored in terms of the maximum intensity of the Q-field. The results show that classic contact angle models based on interface velocity cannot describe the evolution of the contact angle at a macroscopic scale. Moreover, the impact of the interface dynamics on the flow field is considerable and extends to several capillary lengths below the interface.

Analysis of moisture permeability of sheepskin in different parts based on microscopic and water contact angle / Zhong Anhua in JOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC), Vol. 108, N° 3 (05-06/2024)

[article]  inJOURNAL OF THE SOCIETY OF LEATHER TECHNOLOGISTS & CHEMISTS (JSLTC) > Vol. 108, N° 3 (05-06/2024) . - p. 138-141 Titre : Analysis of moisture permeability of sheepskin in different parts based on microscopic and water contact angle Type de document : texte imprimé Auteurs : Zhong Anhua, Auteur ; Chen Xiaoting, Auteur ; Huang Zhuo, Auteur ; Hu Jingxian, Auteur ; Bian Jing, Auteur ; Liu Shaopu, Auteur Année de publication : 2024 Article en page(s) : p. 138-141 Note générale : Bibliogr. Langues : Anglais (eng) Catégories : Angle de contact Cuirs et peaux -- Analyse Cuirs et peaux de moutons Humidité Perméabilité Index. décimale : 675 Technologie du cuir et de la fourrure Résumé : This paper mainly analyzes the moisture permeability of different parts of sheepskin based on microscopic and water contact angle. Firstly, the moisture permeability of the neck, belly, back and hip of natural sheepskin was tested and the change rule of moisture permeability was analyzed. Then the SEM electron microscope pictures and water contact angle data were obtained. Through the analysis of the fibre distribution, the tight arrangement of fibres and the tension of leather surface in different parts of natural sheepskin, the reasons for the formation of this moisture permeability rule were explained. The study found that under the same temperature and humidity conditions, the moisture permeability of sheep skin in different parts is different. On the whole, the moisture permeability of different parts of sheep skin showed the order of belly > hip > back > neck. Microstructure analysis showed that the order of fibre tightness in different parts was neck > back > hip > belly. The natural sheepskin fibres in the belly and hip are loosely arranged, and their water contact angles are also small, which facilitates the passage of water vapour, so they have excellent performance in moisture permeability; the fibres on the back and neck of natural sheepskin are closely arranged, with less voids, and the water contact angle of the skin is also large, which affects the passage of water vapour. Therefore, the performance of moisture permeability is not as good as that of the belly and hip.

Anti-fingerprint coatings / Steven Block in POLYMERS PAINT COLOUR JOURNAL - PPCJ, Vol. 198, N° 4526 (07/2008)  

[article]  inPOLYMERS PAINT COLOUR JOURNAL - PPCJ > Vol. 198, N° 4526 (07/2008) . - p. 16-19 Titre : Anti-fingerprint coatings Type de document : texte imprimé Auteurs : Steven Block, Auteur ; Peter Hupfield, Auteur ; Yasuo Itami, Auteur ; Eiji Kitaura, Auteur ; Don Kleyer, Auteur ; Tetsuya Masutani, Auteur ; Yasuhiro Nakai, Auteur Année de publication : 2008 Article en page(s) : p. 16-19 Langues : Anglais (eng) Catégories : Angle de contact Perfluoropolyéther Propriétés anti-empreintes Revêtements -- Additifs:Peinture -- Additifs Silanes Surfaces -- Nettoyage Index. décimale : 667.9 Revêtements et enduits Résumé : Stay-clean and easy-to-clean surface properties keep surfaces free of contamination from fingerprints and dirt. Achieving oil and water repellency on surfaces is easily obtained with the use of fluoroalkyl-modified silanes. While fluoroalkyl-modified silanes exhibit high static and advancing water and oil contact angles, their low receding contact angles mean the oil and water will not readily slide over the treated surface. The resulting effect of these characteristics yields a surface that is both easy to clean and stays clean longer. Ultimately, modified perfluoropolyether silanes give high static and advancing water and oil contact angles as well as high receding contact angles resulting in a very low sliding angle. The influence of structure modification of the silane and the perfluoropolyether component is examined. Their impact on performance by application method is also discussed.
