Effect of MCM-41 and SBA-15 Mesoporous Molecular Sieves on Properties of PMMA-Based Composite
Effects of different pore size nano-mesoporous molecular sieves fillers, i. e. MCM-41, SBA-15, together with organic-montmorillonite (OMMT), mixture of OMMT/MCM-41 or OMMT/SBA-15 (m (OMMT): m (MCM-41)/m (SBA-15) =1:1) and their amounts on mechanical properties of the polymethylmethacrylate (PMMA) composites were investigated. When the amount of OMMT/SBA-15 mixture was 0.5 %, tensile strength of the nano-composite reached maximum values of 46.3 MPa. When OMMT/SBA-15 mixture addition amount w (filler) was 1.2 %, impact strength of the nano-composite reached maximum values of 14 KJ/m2. In comparison with PMMA without any filler, the tensile strength and impact strength of nano-composite were increased by 8.4 % and 48 %, respectively.
