| Abstract | Metal surfaces with a hydrophobic feature, which could prevent percolation of water droplets and improve their resistance against corrosion, have attracted extensive interest. In this work, we demonstrated a method to prepare a hydrophobic copper surface by coating polydopamine (PDA), and modifying with 1-dodecanethiol (1-DT). Surface hydrophobicity was evaluated by contact angle analysis. Attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR), near infrared (NIR) spectroscopy and X-ray photoelectron spectroscopy (XPS) were employed to understand the structure and composition of the resultant coating at the metal surface. The inhibition efficiency of the optimal hydrophobic surface in 3 wt% NaCl aqueous solution, explored by using electrochemical measurements, was 95.3%, which was due to synergy effects of PDA and 1-DT. The promising inhibition of copper corrosion was also validated by scanning electron microscopy observation. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
