Abstract:
We demonstrate that a chlorinated poly(vinyl chloride) (CPVC) film containing a high-viscosity plasticizer enables stable three-dimensional (3D) manipulation of two-dimensional materials, including atomic-layer origami. In clear contrast to conventional PVC films, the CPVC film prevents flake detachment and allows precise control of folding, realizing diverse 3D morphologies such as multiply and corrugated structures. To clarify why CPVC outperforms PVC, we quantitatively investigated adhesion behavior using adhesive force measurements during tensile detachment. The CPVC film exhibits both strong initial adhesion and a long adhesion-sustaining distance, characteristics that correlate directly with reliable folding operations. This study establishes a framework linking measurable adhesion properties to manipulation performance, providing rational guidelines for stamp material design and advancing high-precision techniques for transfer, stacking, and folding.

Crystalline domains are the regions where polymer chains are aligned in an orderly manner and held together in proximity by intermolecular forces. For example, chains in the crystalline domains of polyethylene and nylon are bound together by van der Waals...
Types of Step-Growth Polymers: Polyesters
Polyesters are commonly prepared from terephthalic acid and ethylene glycol; the crude product is known as poly(ethylene terephthalate) or PET. However, polyesters are synthesized industrially by transesterification of dimethyl terephthalate with ethylene glycol at 150 °C. The two reactants and the polymer...
