Biodegradable polymer film with controlled degree of biodegradability comprising mixture of polyvinyl alcohol and cellulose polymer and preparation method thereof
The invention relates to a biodegradable polymer film with controlled biodegradability comprising a mixture of polyvinyl alcohol and cellulose polymer and a preparation method thereof. By preparing a mixed polymer film comprising PVA and cellulose polymer, tensile strength, biodegradability are increased, degradability is controlled, and since a mixed polymer film comprising PVA and cellulose polymer is degraded after some period, it can be used as mulching film for agriculture and does not have to be collected after use. Since OVA-MC biodegradable polymer film does not remain in a soil for long, it prevents soil contamination and can be used for domestic use, or for vinyl industry or household waste processing industry.
