Surface and Interface Properties of PVDF/Acrylic Copolymer Blends

November 1, 2002
Author(s)
Xiaohong Gu, Tinh Nguyen, Mark R. VanLandingham, D Nguyen
Poly(vinylidene fluoride) (PVDF) is commonly blended with amorphous polymers to improve its optical property. The surface and interface properties of PVDF blended with different amounts of poly(methyl methacrylate) and poly(ethyl acrylate) copolymer (PMMA

Effects of Crosslink Density on Surface and Interface Properties of Amine-Cured Epoxy

February 1, 2002
Author(s)
Xiaohong Gu, Tinh Nguyen, Mark R. VanLandingham, D T. Raghavan
The effect of network changes on the surface and interface properties of amine-cured epoxy has been investigated. Samples of different crosslinked epoxies are prepared by mixing stoichiometrically pure diglycidyl ether of bisphenol A (n=0.03) with

Nanomechanical Measurements of Polymeric Systems

March 13, 2001
Author(s)
Mark R. VanLandingham, Christopher C. White, Xiaohong Gu, Tinh Nguyen
Durability, in terms of service life, is often related to the failure due to service conditions of an unacceptable percentage of a product population. In many cases, this percentage is much less than 1 %, and thus the factors affecting early times-to

Characterization of Coating System Interphases with Phase Imaging AFM

February 1, 2001
Author(s)
Tinh Nguyen, Xiaohong Gu, Mark R. VanLandingham, M Giraud, R Dutruc-Rosset, R Ryntz, D Nguyen
The interphase between a polymer film and a substrate controls the adhesion and durability of a variety of polymeric systems including adhesives, coatings on plastics and metals, and electronic packaging. A polymeric coating system consists of a coating

Characterization of Coating System Interphases With Phase Imaging AFM.

Tinh Nguyen, Xiaohong Gu, M Giraud, M R. VanLandingham, R Dutruc-Rosset, R Ryntz, D Nguyen
The interphase between a polymer film and a substrate controls the adhesion and durability of a variety of polymeric systems including adhesives and coatings on plastics and metals. Interphase formation is affected by processing conditions that control
