Gamma-Ray Modified Polymer/Clay Composites: Synthesis, Characterization, and Formulation Optimization Using Multivariate Calculus and Graph Theory

To enhance the oxidation strength and crosslinking yield of ultrahigh molecular weight polyethylene (UHMWPE), its composites were prepared by mixing 1%, 2%, 3% (by wt.) magnesium silicate hydrous (sepiolite) during this study. These irradiated with 25 kGy 50 irradiation doses in open air. Subsequent to irradiation, characterized for updates structure, strength, degree while estimating values index (OI), crosslink density (Gx), percent crystallinity (Xc), respectively. The reaction modified sepiolite (SP) on irradiating UHMWPE/SP was evident from origination peaks at Si-O, O-Si-O, Si-O-Si, Mg-OH stretching vibration 974 cm−1, 1014 1080 In addition, moderate negative correlation OI (−0.46) strong positive Gx (0.87) absorbed dose, made obvious analysis, confirmed effectiveness SP enhancing UHMWPE. Furthermore, cluster analysis (CA) grouped as low, moderate, best based dissimilarities, i.e., density, which further principal component (PCA). PCA also revealed that OI, Gx, dose active variables group. After confirming (as an filler UHMWPE) recognizing variables, next step determine necessary minimum amount concentration radiation required composite outperforms all others. For this, a parametric graph theory matrix approach employed rank group, revealing 1% Si12O30Mg8(OH)4(H2O)4·8H2O most suitable choice existing alternatives tested Although is first attempt, our knowledge, where smart using multivariate calculus decision-making tools utilized figuring UHMWPE formulation along appropriate treatment results methodology could be extended any polymer industrial scale, such those used medical implants, defense armor, bulletproof jackets, etc.
