NOVELTY - Silicone-based compound (I), is new. USE - (I) is useful in composition for three-dimensional printing and artificial ear (all claimed). ADVANTAGE - (I) can be used as material for 3D printing of stereolithography method; increases sensitivity to detect vibration by adding graphene; can be lowered minimum audible decibel (dB), when the artificial ear is used; exhibits high yield and good regioselectivity; and is economical. DETAILED DESCRIPTION - Silicone-based compound of formula (I), is new. R1, R5, R6, and R10 = 1-20C linear or branched alkyl, 6-20C aryl (both are optionally substituted by G1), O, Si, S, H, F, Cl, Br, or I; R2, R3, R4, R7, R8 and R9 = 1-20C linear or branched alkyl; G1 = 1-6C alkyl, 6-20C aryl, O, Si, S, H, F, Cl, Br, or I; and m, n, x and z = 1-1000. INDEPENDENT CLAIMS are also included for composition for: (1) preparation of (I); (2) composition for three-dimensional (3D) printing, comprising silicone-based compound (I), graphene, and photoinitiator; and (3) artificial ear comprising silicone-based compound (I), graphene, and photoinitiator. DESCRIPTION OF DRAWING(S) - The drawing shows a flowchart illustrating the method for preparation of silicone-based compound (I) (Drawing includes non-English language text).
