    Research output: Contribution to conferenceOtherpeer-review


    Use of structured latex particles and the mechanism of film formation from latexes to produce pressure-sensitive adhesive (PSA) films with controlled sub-micron and nanoscale morphol. has been practiced widely. However, consideration of these materials as soft-soft nanocomposites is new and has led to design of PSAs with enhanced adhesive performance. As part of an EC-funded project entitled "Designed Nanoscale Heterogeneities for Controlling Water-Borne Pressure-Sensitive Adhesive Performance (NsHAPe)", structured particle PSA latexes have been synthesized with the specific aim of producing soft-soft nanocomposite PSA films comprising two interconnected elastomeric phases with controlled differences in crosslink d. Through careful design of the particles, it is possible to produce soft-soft nanocomposite PSA films that show highly viscoelastic behavior at small strains but elastic response at high strains. The particle design parameters that are key to adhesive performance will be discussed and define general principles for enhancing the performance of water-borne PSAs. [on SciFinder(R)]
