The effect of surface roughness and viscoelasticity on rubber adhesion

Abstract: Adhesion between silica glass or acrylic balls and silicone elastomers and various industrial rubbers is investigated. The work of adhesion during pull-off is found to strongly vary depending on the system, which we attribute to the two opposite effects: (1) viscoelastic energy dissipation close to an opening crack tip and (2) surface roughness. Introducing surface roughness on the glass ball is found to increase the work of adhesion for soft elastomers, while for the stiffer elastomers it results in a strong … Show more

“…Most of our adhesion studies were performed on rubber surfaces prepared using the smooth steel mold. This is the same steel mold as was used in [26] (see Section 5.1 in [26]). Experimental results: Figure 10 shows the interaction force between a glass ball and Rubber Compound A as a function of time.…”

“…Мы изучили адгезионное взаимодействие между стеклянным (soda-lime silica glass) шаром и образцом ПДМС с помощью той же установки, что использовалась нами ранее [9]. В ходе экспериментов мы приводим шар диаметром 2R = 2.5 см в контакт с подложкой эластомера, как показано на Рис.…”

“…но выше, чем w ≈ 0.25 Дж / м 2 для ПДМС 10 :1, связанные при повышенной температуре [9]. Мы объясняем это тем, что материал ПДМС образцов 4 и 5 не полностью связан, что имеет два последствия, а именно: (а) увеличивается внутреннее трение в материале, что приводит к существенному вязкоупругому вкладу в работу адгезии, и (б) образцы ПДМС необратимо деформируются в области контакта [13].…”
