Furthermore, the coefficient of the expansion curve shows an evident inflection point under low temperature as pointed by the blue dotted line in Fig. 8. This is a result of glass transition in PDMS material.

WebNov 1, 2016 · The CTE for all the composites monotonically decreases with increasing the amount of MWCNT. Compared with the MWCNT/PDMS, more significant reduction of CTE has been observed in 3D-MWCNT/PDMS composites. This indicates that the 3D architecture constructed from MWCNT sponge within the PDMS matrix can enhance the … The chemical formula of PDMS is CH3[Si(CH3)2O]nSi(CH3)3, where n is the number of repeating monomer [Si(CH3)2O] units. Industrial synthesis can begin from dimethyldichlorosilane and water by the following net reaction: n Si(CH3)2Cl2 + (n + 1) H2O → HO[−Si(CH3)2O−]nH + 2n HCl The polymerization … See more Polydimethylsiloxane (PDMS), also known as dimethylpolysiloxane or dimethicone, belongs to a group of polymeric organosilicon compounds that are commonly referred to as silicones and siloxane. … See more PDMS is hydrophobic.
