•Calcium silicate containing mesoporous SiO2 (CaSiO3@SiO2)was grafted onto PP non-woven.•PP-g-CaSiO3@SiO2 was characterized by SEM, FTIR, DSC, BET and XRD.•PP-g-CaSiO3@SiO2 possessed high surface area with a uniform pore of 7.5 nm.•PP-g-CaSiO3@SiO2 adsorbed more bisphenol A than PP and PP-g-CaSiO3 fiber.•PP-g-CaSiO3@SiO2was prepared simply without using any organic solvent.
Calcium silicate particles containing mesoporous SiO2 (CaSiO3@SiO2) on the surface was grafted onto polypropylene non-woven fabric. First, polyacrylic acid grafted PP non-woven (PP-g-AA) was prepared by UV irradiation graft and sodium polyacrylate PP non-woven (PP-g-COONa) was synthesized after neutralization by NaOH. Then calcium silicate grafted PP non-woven (PP-g-CaSiO3) was synthesized by dipping PP-g-COONa in Na2SiO3 solution and crosslinking by CaCl2. After modification by hydrochloric acid solution, PP non-woven grafted calcium silicate containing mesoporous SiO2 (PP-g-CaSiO3@SiO2) was obtained and characterized by SEM, FTIR, DSC, BET and XRD. The PP-g-CaSiO3@SiO2 was prepared simply without using any organic solvent, and can be used in the fields of organic adsorption, separation, drug release, tissue engineering and catalysis.
