The role of nano-sized resin fillers on the fracture and viscoelastic behavior of silicones was examined in the context of thermal aging. Systems with different resin volume fractions and resin glass transition temperatures were compared. X-ray scattering patterns were collected over a wide range of q-values in order to provide insight into the physical structure of the silicone elastomers. Additionally, tensile, dynamic mechanical, and fracture tests were performed. Temperature shift factors obtained from the dynamic mechanical data were used to obtain master plots of the fracture toughness as a function of reduced crack velocity. The elastic modulus for each of the materials increased as a function of thermal aging time, and the high-temperature fracture behavior for each of the systems was reduced to values characteristic of unfilled systems after 14 days of aging at 200 8C. In order to obtain an accurate representation of the viscoelastic response of the materials in the megahertz frequency regime, quartz crystal resonators were used to measure mass changes and rheological properties after thermal aging. The results are consistent with a simple picture of dynamic heterogeneity, where high toughness requires that regions with different dynamic properties exist within the sample.

Silicone pressure-sensitive adhesives compositions contain a polydimethylsiloxane and a silicone resin, which can enhance the instant bonding ability and bonding strength of the adhesive. In this study, silicone resin was designed to have a low molecular weight and a highly nonpolar chemical structure. The silicone resin was applied to silicone pressure-sensitive adhesives. The molecular structure of silicone resin was characterized by FT-IR, GPC, 1 H-NMR, and 29 Si-NMR spectroscopic techniques. Properties such as thermal stability, solubility, hydrophobic, and transparent properties were researched and compared. When the chlorotrimethylsilane increased, it appeared that the amount of silanol groups, molecular weight and thermal stability decreased, while the hydrophobic and transparent properties increased. The silicone resin was completely soluble in toluene and xylene. It was also applied to silicone pressure-sensitive adhesives, resulting in good peel adhesion.

Silicone‐Based Adhesives with Highly Tunable Adhesion Force for Skin‐Contact Applications

A fundamental approach to fabricating silicone-based adhesives with highly tunable adhesion force for the skin-contact applications is presented. Liquid blends consisting of vinyl-multifunctional polydimethylsiloxane (V-PDMS), hydride-terminated PDMS (H-PDMS), and a tackifier composed of a silanol-terminated PDMS/MQ resin mixture and the MQ resin are used as the adhesive materials. The peel adhesion force of addition-cured adhesives on the skin is increased by increasing the H-PDMS molecular weights and the tackifier content, and decreasing the H-PDMS/V-PDMS ratio. There is an inverse relationship between the adhesion force and the Young's modulus. The low-modulus adhesives with a low H-PDMS/V-PDMS ratio exhibit enhanced adhesion properties. The low-modulus adhesives with the high MQ resin content show significantly enhanced adhesion properties. These adhesives exhibit a wide range of modulus (2-499 kPa), and their adhesion force (0.04-5.38 N) is superior to commercially available soft silicone adhesives (0.82-2.79 N). The strong adhesives (>≈2 N) provide sufficient adhesion for fixing the flexible electrocardiogram (ECG) device to the skin in most daily activity. The human ECG signals are successfully recorded in real time. These results suggest that the silicone-based adhesives should be useful as an atraumatic adhesive for the skin-contact applications.
