A microplastic capture system includes a base and a plurality of hair-like protrusions mounted to and extending from the base. An oil is applied to the plurality of hair-like protrusions. The oil and hair-like protrusions are positioned to capture microplastic particles due to interfacial forces that oppose a force generated by momentum of the microplastic particles.

This invention relates to the field of release film technology and discloses a low-adhesion self-adhesive release film and its preparation method, comprising: a substrate layer, a first buffer layer, a heat-stabilizing layer, a second buffer layer, an elastic reinforcing layer, and an improved release layer; the substrate layer uses polyester film as a supporting structure to provide mechanical strength and dimensional stability; the first buffer layer is disposed on the substrate layer and is tightly connected to the substrate layer by hot-pressing to initially absorb thermal stress. This low-adhesion self-adhesive release film and its preparation method utilize a six-layer composite structure design to prevent surface energy fluctuations from amplifying interfacial force changes, thereby reducing peeling difficulties and deformation at high temperatures and avoiding insufficient contact and lifting at low temperatures. The synergistic effect of the six layers further solves the overall instability caused by temperature sensitivity, reduces bonding misalignment and automatic peeling during production, and improves the reliability and environmental resistance of the bonding system.
