Transparent and Thermoplastic Silicone Materials Based on Room-Temperature Diels-Alder Reactions

Paria Azadi Namin et al.

Summary: A translucent silicone material with Diels-Alder cross-links was synthesized using a chemoenzymatic method. The material showed a curing time of 5 h at room temperature and could be repaired within <5 min using a low-temperature regimen. All synthesized materials were thermoplastic and could be remolded while retaining the bulk properties of the parent material. The healed scars of the materials were robust and catastrophic failure occurred outside of these locations during elongation of repaired materials. This is the first reported case of a room-temperature curing cross-linked silicone material based on the Diels-Alder reaction.

Antioxidant Silicone Elastomers without Covalent Cross-Links

Khaled Tamim et al.

Summary: Improved sustainability can be achieved by using elastomers that biodegrade easily in the environment and can be reprocessed/reused well before reaching the end of their lifespan. In this study, we developed silicone elastomers with both thermoplasticity and antioxidant activity. By combining ionic and hydrogen bonding, natural phenolic antioxidants such as catechol, pyrogallol, and tannic acid were linked to telechelic aminoalkylsilicones. The mechanical properties of the elastomers, including their processability, were found to be optimal when the [ArOH]/[H2NR] ratio exceeded 1:1.

Exploring Lipoic Acid-Mediated Dynamic Bottlebrush Elastomers as a New Platform for the Design of High-Performance Thermally Conductive Materials

Sijia Zheng et al.

Summary: The development of high-performance thermally conductive interface materials is crucial for addressing the heat dispersion problem in modern microelectronics. However, existing methods have limitations in terms of physical traits and processability. In this study, we propose a novel approach using malleable silicone matrices based on α-lipoic acid cross-linker to create highly efficient thermal conductive composites. These composites have a 3D interconnecting, thermally conductive network and show great potential in advanced electronics, as demonstrated by applications in LEDs and CPUs.

Thymine-Modified Silicones: A Bioinspired Approach to Cross-Linked, Recyclable Silicone Polymers

Laura J. J. Voigt et al.

Summary: In this work, the natural hydrogen bonding capacity of thymine was used to produce silicone polymer systems that can be cross-linked by hydrogen bonds. These thymine-modified polymers displayed thermal absorptions and releases, indicative of bond breaking and reformation, and showed the ability to be recycled and remolded through heating and cooling.

Reversible Redox Crosslinking of Thiopropylsilicones

Sijia Zheng et al.

Summary: Most silicone elastomers are thermosets, but this study reports on the development of silicone elastomers that can be reversibly cured and uncrosslinked using redox conditions. The mechanical properties of these elastomers can be adjusted by varying crosslink density. The oxidation and reduction cycle results in comparable thermal stabilities and significantly improved water wettability on the elastomer surface.

Silylating Disulfides and Thiols with Hydrosilicones Catalyzed by B(C6F5)3

Mengchen Liao et al.

Summary: Studies have shown that hydrosilanes and silicones catalyzed with B(C6F5)(3) can be used to silylate thiols or cleave disulfides, resulting in silyl thio ethers, with alcohols reacting faster than thiols or disulfides. The overall order of reactivity is found to be HO>HS>SS>SiOEt. The resulting silane and silicone-protected thio ethers from sulfur-based functional groups can be cleaved to thiols using alcohols or mild acid, depending on the steric bulk of the siloxane.

Light-Mediated Synthesis and Reprocessing of Dynamic Bottlebrush Elastomers under Ambient Conditions

Chungryong Choi et al.

Summary: A novel grafting-through polymerization strategy was introduced to synthesize dynamic bottlebrush polymers and elastomers using light to construct a disulfide-containing backbone. The key starting material, alpha-lipoic acid (LA), is commercially available, inexpensive, and biocompatible. The resulting bottlebrush elastomers exhibit high gel fractions and tunable shear moduli, with the added benefit of dynamic disulfide bonds allowing for self-healing and on-demand chemical degradation.

Thermoplastic silicone elastomers from divanillin crosslinkers in a catalyst-free process

Robert Bui et al.

Summary: Silicone elastomers are typically difficult to recycle, but thermoplastic silicone elastomers using divanillin as a crosslinker offer better flexibility compared to traditional petroleum-based ones. Pendent-derived elastomers exhibit solvent swelling and dynamic adhesion at interfaces, while telechelic polymer-derived elastomers are more susceptible to heat or solvents.
