Remarkable Toughening of Plastic with Monodispersed Nano-CaCO3: From Theoretical Predictions to Experimental Validation

“…Polymer crystallization induced by the fillers, which have a chemical nature similar to that of the matrix and act as nucleation centers, is a promising way to achieve strong filler–matrix interfacial bonding action and then balance the toughness and stiffness for the goal of high-performance general plastics. − XRD patterns of pure PVC and PVC/CaCO 3 were used to qualitatively compare their crystallization degree, which showed typical amorphous peaks at 2θ = 24.1° and 2θ = 39.6° for pure PVC and an apparent crystallization peak at 2θ = 19.1° for PVC/CaCO 3 (Figure S12). Quantitative comparison of the crystallization degree can be realized by the crystallinity index ( X t ), which denotes the ratio of the melting heat of the crystalline part of the polymer, which is the integral area of the concave region of the DSC cooling curve, , to the theoretical enthalpy of 100% crystalline polymer, which is 43.932 J g –1 for PVC Figure h.…”

“…Quantitative comparison of the crystallization degree can be realized by the crystallinity index (X t ), which denotes the ratio of the melting heat of the crystalline part of the polymer, which is the integral area of the concave region of the DSC cooling curve, 2,73 to the theoretical enthalpy of 100% crystalline polymer, which is 43.932 J g −1 for PVC. 74 X t results of the nanocomposites are summarized and fitted, and the fitting curve is shown in Figure 4h. Insets show the DSC cooling traces of pure PVC and PVC/CaCO 3 -12% to display the differences in the melting heat.…”

Programming Chain Distribution of Branched Polymers via Bond Exchange Reactions

“…In molecular simulations, triaxial extension is employed to characterize the toughness of materials. , The method allows systems to expand in volume during stretching, leading to the formation of cracks, voids, and eventual fractures. The dissipation work, derived from the stress–strain (− P ZZ – ε T ) curve obtained from triaxial stretching, enables a qualitative comparison of the toughness among different systems.…”

“…This method has been proven to be a feasible approach. 52,53 In the simulations, the simulation box is deformed solely in the Z-axis direction, while the lengths in the X-axis and Y-axis directions are kept constant. The deformation is carried out at a constant engineering strain rate T…”

A thin, intrinsically stretchable MXene-MWCNTs/polymer current collector for deformable aqueous Li-ion batteries

“…46,47,73 Ti 3 C 2 T x and MWCNTs have been proven to possess metallic conductivity, 74,75 and their integration also leads to high electronic conductivity. 76,77 Here, by depositing the conductive Ti 3 C 2 T x –MWCNT ink on the SEBS film (Scheme 1), we proposed the use of a highly surface conductive Ti 3 C 2 T x –MWCNTs/SEBS (TMS) current collector to fabricate a thin, intrinsically stretchable aqueous LIB with a separator-free and coplanar design. In this work, the TMS current collector and the stretchable battery have a strain ability of 100% and 50%, respectively.…”
