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

Sijia Zheng,
Haiyan Xue,
Jun Yao
et al.

Abstract: The development of high-performance thermally conductive interface materials is the key to unlocking the serious bottleneck of modern microelectronic technology through enhanced heat dispersion. Existing methods that utilize silicone composites rely either on loading large doses of randomly distributed thermal conductive fillers or on filling prealigned thermal conductive scaffolds with liquid silicone precursors. Both approaches suffer from several limitations in terms of physical traits and processability. W… Show more

“…[141][142][143] Furthermore, recent advances regarding the polymerization of thiolanes (especially with lipoic acid as a comonomer) have made an in situ grafting-through strategy a viable route to synthesize bottlebrush polymers and networks (Scheme 3b). [144][145][146][147][148][149] Such materials boast interesting thiolane end groups, which participate in the formation of transient disulfide bonds -adding an additional mechanism for toughening within synthesized materials. [144][145][146][147] The additional benefits afforded by 3D printability also position UV-Thiol generated bottlebrush matrices as ideal candidates for future applications of encapsulation in phase change materials, though thus far bottlebrush phase change materials have been limited to those with alkyl chains supporting thiol groups.…”

“…The excellent thermal stability (Figure S10, Supporting Information) and soft merits of the bottle brush LPA were manifested as excellent matrices for constructing TIM in our previous work. [29] The thermal curing process leads to the immobilization and permanent binding of the LM-PBs. The morphology of the LM-PBs/GLAP was investigated by an optical microscope.…”

“…The products exhibit an excellent thermo-conductive response, a stress-dependent reversibility, and the ability to be reprocessed. 37 We wished to develop methods that would permit the preparation of silicone LPA elastomers under much milder conditions. In this paper, we report that the formation of silicone lipoamides was accompanied by concomitant ringopening polymerization (ROP) of the LPA at room temperature to give thermoplastic silicone/LPA elastomers that ranged in properties from viscous oils to rigid elastomers.…”
