Methods and Products to Protect Against Root Intrusion and Plant and Root Growth

摘要

Method for forming a control device for control of one or more of root intrusion or plant growth commences by heating a root-controlling agent to its melting point temperature and heating a nanoclay intercalated with an ammonium ion to a temperature of at least the root-controlling agent melting point temperature. The heated root-controlling agent is loaded with the heated intercalated ammonium ion intercalated nanoclay to form a composite material that is partially exfoliated. The particle size of said composite material is adjusted for blending and further exfoliation. The particle size of the composite material is adjusted with a polymer matrix. The nanoclay in the polymer matrix is exfoliated to an extent that a slow controlled release of the root-controlling agent from the polymer matrix is obtained. Finally, the polymer matrix is formed into a fiber to form the control device.
