“…Recent studies have shown that, the thickness of poly (L-lysine) (PLL)/hyaluronan (HA) and Cationic starch/ anionic starch film are increases initially with but decreases with higher ionic strength concentration [18,52]. We also showed that the ionic strength dependence of theQC/CMC film thickness differs from that of synthetic polyelectrolyte complex thin films: With increasing the ionic strength, the growth becomes slow when adding 0.5 M NaCl, the thin film growth is almost hindered [40].…”

“…All solutions employed in one multilayer formation process are adjusted to the same pH value, even the washing solution. During the switching of the assembling solution, the solvent (60 µL/min) was followed for several minutes to rinse the chamber and the all experiments were conduct at 25 ± 0.02°C [40].…”

“…As the ionic strength increases, the film growth is gradually restricted. Increasing the temperature accelerates the thickness growth of the films, but the film becomes rough and the transparency decreases [9] . The main focus of this work is to explore how the operational parameters influence the assembly growth of (CMC) and (QC) thin film.…”

Positively charged cellulose derivative quaternized cellulose (QC), was layer-by-layer (LbL) assembled with negatively charged cellulose derivative carboxymethyl cellulose (CMC) to produce the thin film. The factors of dipping and rinsing time on the thin film growth were investigated. FT-IR confirmed that QC and CMC can be layer by layer assembled in different dipping and rinsing time. As dipping time increases, the thickness of fabricated QC/CMC thin film will increase, while increasing rinsing time leads to decrease in the thickness of the QC/CMC thin film.

Manipulation and engineering of the surfaces has a key role in improving the materials properties. Anchoring of thin hydrogels on the materials surface is one of the recently developed methods to achieve surfaces with high potential applications. Layer‐by‐layer (LBL) has been used widely as a strong strategy for immobilization of thin hydrogel films on the surface of various organic/inorganic substrates. Electrostatic LBL and covalent LBL are two main strategies used in this regard. In electrostatic LBL, negatively and positively hydrophilic polymers are sequentially assembled to create a multilayer hydrogel which subsequent covalent crosslinking of multilayers improved the stability of the inserted layers. On the other hand, covalent LBL requires hydrophilic polymers bearing reactive telechelic groups. These reactive polymers are prepared by various polymerization techniques or by post‐functionalization of biopolymers. The principles of hydrogel anchoring have described along with representative examples. Besides, the potential applications of the modified surfaces in specific cases have been addressed and overviewed.
