Summary: This study focuses on the humidity-sensing performance of 1,6-hexanediamine modified graphene oxide and functionalized multiwall carbon nanotube composites. The relative resistance response of the sensors can be tuned by varying the content of fMWCNTs, with a 1:4 mass ratio showing high response, repeatability, and stability. The decrease in mass proportion of fMWCNTs is found to lower response time and hinder the recovery process, with the resistance change over a wide range of humidity levels fitting well with the Henry-clustering model.

Summary: This study investigates the humidity response mechanism and regulation methods of carbon nanocoils (CNCs). Experimental results show that NH3H2O treatment greatly suppresses humidity response, while annealing suppresses both humidity and temperature response. Due to the defects and functional groups in CNCs, NH3H2O treatment prevents further humidity response.

Summary: In this study, a natural rubber (NR) filled with a hybrid filler of carbon nanotube (CNT) and cellulose nanofiller (CNF) was prepared by the masterbatch latex mixing method. The mechanical, electrical, and strain-sensitive properties of the hybrid NR nanocomposites were investigated. The results showed that there was interaction between CNT and CNF, leading to optimal dispersion and electrical conductivity in the CNT-CNF1:0.05 hybrid. However, at high CNF proportions, agglomeration of CNT and CNF particles occurred, but a stable and flexible conducting network was formed in the hybrid NR nanocomposites, enhancing their strain-sensitive property for sensor applications.

Summary: This study reports on the rapid melt crystallization of Bisphenol-A polycarbonate induced by pressure and shear flow, achieving a crystallinity of up to 25% in 60 minutes, which is 500 times faster than quiescent melt crystallization under ordinary pressure. The synergistic effect of pressure and flow in promoting crystallization kinetics of PC is highlighted, reducing the critical shear rate for nucleation effectively. A critical specific work of flow is identified, above which PC can crystallize, potentially revolutionizing our understanding of crystallization in similar polymers with rigid chains.

Summary: The interfacial crystallization of polyoxymethylene/poly(butylene succinate) blends induced by polyamide 6 (PA6) fiber was investigated. The PA6 fiber exhibited strong heterogeneous nucleating ability, generating dense nuclei on its surface and compelling the growth of twisted lamellae perpendicular to the fiber. This resulted in the formation of unique interfacial banded transcrystallization. The nucleation density and architecture of the banded transcrystallization were influenced by the crystallization temperature, with higher temperatures leading to decreased nucleation density and transformed stripe patterns.

Summary: The structural evolution of propylene-ethylene copolymer (coPP) and propylene-ethylene copolymer/polypropylene (coPP/iPP) films during a tensile process was studied. Both types of films showed melt-recrystallization during deformation. At low strain rate, molecular chains were easier to pull from the lattice, resulting in decreased crystallinity in the films. Interestingly, there was a difference in the growth process for lamellae between coPP and coPP/iPP samples.
