Researchers of Ferdowsi University of Mashhad have developed pressure sensitive adhesive through applying nanotechnology and emulsion polymerization of core-shell technique.

According to an ISCA report, researchers used different values of acrylic acid monomer for preparation of the adhesive base on core-shell morphology.

Based on the research, “pressure sensitive adhesives (PSAs) are viscoelastic materials that can adhere strongly to solid surfaces upon application of light contact pressure and short contact time.

“In this paper, different values (0.56, 1.12, 1.67 and 2.21 wt%) of acrylic acid monomer have used in the preparation of the adhesive. The shear strength of the obtained adhesive increased (from 397 kPa to 501 kPa) with increasing acrylic acid concentration from 0.56 w% to 2.21 w% which studied.

“Improvement of the shear strength with addition of the acrylic acid could be due to presence of COOH polar group affected on the adhesion of the PSAs.”

The research was done by Hossein Safdari Torkaman, Gholam Hossein Zohuri , Mehran Gholami and Pedram Hosseinpour Tousi from Department of Chemistry, Faculty of Science, Ferdowsi University of Mashhad.
