Summary of "Phase separation-induced superhydrophobic polylactic acid films."

Superhydrophobic films that are simple, inexpensive, corrosion-resistant and multifunctional are in high demand for industrial applications. We propose a simple and economical phase separation method for fabricating superhydrophobic films using polylactic acid (PLA), nano-SiO2 and a mixture of good and poor solvents to construct a rough surface with a nano/microstructured morphology. The phase separation-induced superhydrophobic PLA/SiO2 composite film with a porous network structure has a water contact angle greater than 164°. This method can be applied to a variety of surfaces or used in large-scale industrial production. The fabricated superhydrophobic films may be applied in biological fields because PLA is a good biodegradable material.

Medical and Biotech [MESH] Definitions

Works consisting of nonfiction films and video designed to teach, instruct, or train. (From Moving Image Materials: Genre Terms, 1988)

The interval between two successive CELL DIVISIONS during which the CHROMOSOMES are not individually distinguishable. It is composed of the G phases (G1 PHASE; G0 PHASE; G2 PHASE) and S PHASE (when DNA replication occurs).

Traumatic or experimentally induced separation of the head from the body in an animal or human.

The phase of cell nucleus division following PROMETAPHASE, in which the CHROMOSOMES line up across the equatorial plane of the MITOTIC SPINDLE APPARATUS prior to separation.

Functionalization of exogenous substances to prepare them for conjugation in PHASE II DETOXIFICATION. Phase I enzymes include CYTOCHROME P450 enzymes and some OXIDOREDUCTASES. Excess induction of phase I over phase II detoxification leads to higher levels of FREE RADICALS that can induce CANCER and other cell damage. Induction or antagonism of phase I detoxication is the basis of a number of DRUG INTERACTIONS.
