The scratch behavior of model epoxy resins with varying degrees crosslink density was investigated according to the ASTM D7027/ISO 19252 test methodology. Three systems low, medium, and high crosslinking densities were prepared systematically investigate how might be influenced. effect on onset groove, crack plowing formation during scratching investigated. Coefficient friction measurements, uniaxial tensile compressive stress-strain curves, dynamic mechanical analyses conducted correlate...
The fracture behavior of polyrotaxane (PR)-modified poly(methyl methacrylate) (PMMA) was investigated. PR is a supramolecule with rings threaded onto linear backbone chain, which capped by bulky end groups to prevent the from de-threading. ring structure α-cyclodextrin (CD), and it can be functionalized enhance its affinity hosting polymer matrix. Adding only 1 wt % containing methacrylate functional (mPR) at terminal some polycaprolactone-grafted chains on CD promotes massive crazing,...
Abstract The mechanical and scratch behaviors of polyrotaxane (PR) modified poly(methyl methacrylate) (PMMA) were investigated. PR is a necklace‐like supramolecule with rings threaded onto linear backbone chain that capped by bulky end groups. Cyclodextrin (CD) serves as the ring structure can be functionalized to induce specific interactions hosting polymer matrix. To systematically investigate effect CD functionalization on properties PMMA, polycaprolactone (PCL) grafted chains CD,...
