Potassium hexatitanate whiskers are prepared and characterized in this study. The reinforcement of polyethylene with potassium is also investigated. through the calcination TiO2 K2CO3 at 1000 °C. It determined that a polyvinylpyrrolidone additive crucial for formation slender rod-like structures smooth flat surfaces high length-to-diameter ratio. For surface modification whiskers, γ-aminopropyl triethoxysilane has been identified as most effective coupling agent enhancing mechanical properties. have little change shape after modification, majority still retain considerable results tests indicate tensile strength modulus elasticity, well shear enhanced to some extent. elasticity increase by 18.6% 3.6%, respectively. modified composites show softness elasticity. elongation break PE/PHT-2-1 increases significantly 38.1%, exceeding unfilled (6.84%). Nevertheless, suitable method established reinforcing thermoplastic polymers using inexpensive whiskers.
