An Investigation on Novel Poly(thiourea-amide)-based Nanocomposites Reinforced with Silica Nanotubes

A straightforward condensation technique was used to prepare new poly(thiourea-amide) (PTA), in this attempt. Halloysite silica nanotubes (SiNTs) were prepared and utilized as fillers to produce novel organic-inorganic hybrid materials. Fine compatibility in PTA/SiNTs was confirmed by FESEM; where halloysite filler render unique uniformly and spherically pact morphology. SiNTs loading in polyamide produced mechanically and heat stable nanocomposites. Consequently, tensile strength of hybrids increased with SiNTs content 52.17-55.24 MPa. A 10% gravimetric loss (516-559 degrees C) and glass transition temperature of PTA/SiNTs (161-168 degrees C) also were shown to be noteworthy. Using silica nanotubes, nanohybrids with fine potential for several applications can be obtained.
