Poly(dibutyl itaconate-co-isoprene-co-methacrylic acid) (PDIM)/halloysite nanotubes (HNTs) nanocomposites with strong interfacial interaction were prepared by co-coagulation of PDIM latex and HNTs aqueous suspension, followed by mechanical kneading with rubber additives. The interfacial interaction, thermal properties, morphology, and mechanical properties of the nanocomposites were investigated. The hydrogen bonds were confirmed in the nanocomposites. Morphology investigation showed uniform and individual dispersion of HNTs in the PDIM matrix. With the incorporation of HNTs into the PDIM matrix, the tensile strength and the fracture energy were significantly improved without sacrificing the extensibility. The improved mechanical properties were correlated to the co-coagulation and the strong hydrogen bonds. Especially, the morphology investigation of tensile fracture surfaces revealed a mechanism for the improved mechanical performance, in which the stress was efficiently transferred from PDIM to HNTs via hydrogen bonds and then the dissociation of the hydrogen bonds dissipated energy to increase the fracture energy of the nanocomposites.

聚（二丁基itaconate-共-isoprene-共通过将PDIM胶乳和HNTs的水悬浮液共混凝，然后与橡胶添加剂进行机械捏合，可制得具有强界面相互作用的β-甲基丙烯酸）（PDIM）/硅藻土纳米管（HNTs）纳米复合材料。研究了纳米复合材料的界面相互作用，热性能，形态和力学性能。在纳米复合物中证实了氢键。形态学研究表明，HNTs在PDIM基质中均匀分散。通过将HNT掺入PDIM基质中，可在不牺牲可延展性的情况下显着提高抗张强度和断裂能。改善的机械性能与共凝聚和强氢键相关。尤其，
