Abstract: In order to replace “carbon” with “silicon” for the synthetic leather coating materials,
polydimethylsiloxane (PDMS) polymer coatings were prepared by in situ polymerization reaction under

(PMHS), divinyl-terminated polymethylvinylsiloxane ( PMVS ) and fume silica as main raw materials.
Organosilicon synthetic leather was prepared by fitting PDMS polymer coating with base cloth. The
structure and mechanical properties of PDMS polymer coatings were characterized by FTIR and electronic

active hydrogen, PMVS and fume silica on the tensile strength, elongation at break and hardness of
PDMS polymer coating were investigated. The thermal properties, low-temperature flexing, abrasive
resistance, hydrophobic and antifouling properties of organosilicon synthetic leather coating were tested.

The results showed that when the mass fraction of PMVS and fume silica was 7% and 40% respectively,
the mechanical properties of PDMS polymer coating film were improved most significantly. The tensile
strength of the PDMS polymer coating prepared under the optimized conditions was 5.96 MPa and the
elongation at break was 481%. The synthetic leather coating exhibited excellent low-temperature flexing,
abrasive resistance, hydrophobic and anti-fouling properties.
