Chitosan/Bioglass composite films by dip-coating method

SrBi2Nb2O9 Thin Films Deposited by Dip Coating Using Aqueous Solution

A new approach for SrBi2Nb2O9 (SBN) thin ®lms synthesis using aqueous solution was successfully experienced. The deposition solution was prepared from Sr±Bi±Nb mixed-citrate solution, requiring no special atmosphere and using common reagents. Films were deposited by dip coating onto Pt/Ti/SiO2/ Si(100) substrates and heat treated at temperatures ranging from 300 to 700 C. The process of formati...

Electrochromic TiO2, ZrO2 and TiO2-ZrO2 thin films by dip-coating method

Sol-gel processing of TiO2, ZrO2 and mixed Ti/Zr oxide thin films has been studied as application of these coatings in electrochromic devices. Their structural transformations as a function of annealing temperatures were analyzed by XRD and FTIR techniques. Electrochromic behavior of the three kind materials was investigated by cyclic voltammetry and the basic electrochromic characteristics wer...

Mechanical Coating Technique for Composite Films and Composite Photocatalyst Films

Optically monitored dip coating as a contactless viscometry method for liquid films.

Real-time interferometric monitoring of the dip coating process is applied to the study of properties of flowing liquids. Nonvolatile Newtonian oils are considered, allowing validity of a simple model after the steady state is reached where film physical thickness depends on time as t(-1/2). Measurement of two distinct mineral oil standards, under several withdrawing speeds, resulted in kinemat...

Synthesis and characterization of nHA-PLA composite coating on stainless steel by dip-coating process for biomedical applications

316L stainless steel is the most commonly used metallic material in the manufacture of orthopedic implants. To achive better properties metal implants often coated with biocomposites. A sol–gel method was used for coating of Poly lactic acid (PLA)/Hydroxyapatite nanopowder (nHA) on stainless steel 316L substrate. The X-ray diffraction (XRD) and Fourier transform infrared spectroscopy (FTIR) wer...
